GENERAL QUESTIONS

How often should I change or clean my air conditioner filters?
Filters should generally be replaced every month when the system is running. Replace filters with the same kind and size as the original filter. If your filter is not disposable, follow the manufacturer instructions for cleaning.

Where is my air filter located?
Your air filter should be located in either the blower compartment of the furnace, in an attached filter case, or in a return air grille in a wall of your home. If you cannot find the air filter, contact us for assistance.

Where can I purchase filters for my air conditioner / furnace?
If you are unable to find the appropriate-size air filter at your local hardware outlet, you can contact us.

Why is a matched HVAC system so important?
A matched system is important for a variety of reasons. One is comfort. When all your components are properly sized to your home, you can control exactly how much heating or cooling you need so you can relax. Also, a properly sized matched system enables every component to perform as designed, meaning proper cycle times are maintained, humidity is controlled, and system sound is minimized.
Another reason matched systems are important is efficiency. Most systems people buy are too large for their homes, meaning they pay to heat and cool space that isn't even there. A matched system outlined when we've completed a load calculation for your home provides just the right amount of heating and cooling you need so you get the most value for your utility dollar.

What are the advantages of an HVAC unit with a variable speed fans?
Variable speed fans operate on a simple principle: they are able to spin at different speeds depending on the heating and cooling needs of your home. Usually, they operate at lower speeds, delivering a steady, reliable stream of warm or cool air to your home. This helps control humidity levels, utility costs and system noise. When conditions become more extreme, the fan speed increases so that the system can meet increased demand, guaranteeing that on even the hottest days or coldest nights, you're comfort needs will be met.

How does a whole-home air cleaner like Lennox PureAir™work as part of my system?
Lennox PureAir™ is designed to perfectly fit as a component of your total home comfort system. Unlike many air cleaners that are situated in a single room of the house, the PureAir™ is installed and operated through the same duct work that your furnace or air handler might use. So even though it's attractively designed, it operates out of sight of most living spaces to provide up to 99.98% cleaner air throughout your entire home.

What is a SEER rating and how does it impact my energy costs?
SEER means Seasonal Energy Efficiency Ratio. Like its "mpg" counterpart in the automotive industry, the SEER gives an indication of the performance efficiency of the system. The higher the SEER, the more efficient the unit. And, the more efficient the unit, the lower the operating costs. Experts say that by purchasing a system with a high SEER, you'll use less energy to cool your house, resulting in lower electric bills. In many cases, these savings are enough to partially or fully offset the cost of the new equipment within a few years.

What do all those rating numbers mean?
The federal government requires all air conditioning and heating equipment to be rated for efficiency. The higher the rating, the more efficient the model. Gas furnaces are rated for (Annual Fuel Utilization Efficiency). This defines the amount of heat used to warm your home from the burned fuel. A 90% furnace will use 90% of the available heat to heat your home. 10% of the heat is vented outdoors. Many older gas furnaces are only 60% efficient. The other 40% is vented outdoors. You can see that a new high-efficiency furnace will require much less fuel to heat your home. For air conditioning, the rating is (Seasonal Energy Efficiency Ratio). This rating is based on general design criteria such as the compressor and outdoor coil. SEER ratings are for comparison purposes only, so that homeowners will know how they can compare different brands of products with similar efficiency ratings. The rating for the outdoor unit will reference a general efficiency range, such as 14 SEER. The actual efficiency rating for a specific system will depend on the combination of the outdoor unit and the indoor coil. These ratings are available from us and the Air-Conditioning and Refrigeration Institute's Energy Guide. A variable-speed indoor blower unit will increase the efficiency rating of the system, as well. Heat pumps are rated by SEER for cooling efficiency and by (Heating Seasonal Performance Factor) for heating efficiency. As with other ratings, the higher the HSPF, the less energy it will take to warm your home.

I need a new outdoor condenser, but my air handler / furnace still works fine. What are the advantages of replacing my whole air conditioning and heating system at the same time?
We recommend that your replace the indoor coil or air handler when replacing the outdoor unit. Both of these components are integral to the closed refrigerant loop and together determine the capacity and efficiency of your system. If you do not replace the indoor unit, there will be no test data available for the new combination to establish the expected capacity or efficiency of your system. Also, the indoor system may be partially blocked by particles that will decrease efficiency, and you may be faced in the near future with replacing the indoor unit after it fails and having to pay to have the closed refrigerant system opened again. It would be expensive and be another opportunity for contamination. You end up paying more. If your whole system is replaced, you will be less likely to need service in the near future.

What noise factors do I need to consider when selecting an air conditioner or heat pump?
The industry sound rating numbers are complicated and often difficult to understand. Sound rating is just one of these areas. A difference of 6 decibels (such as between 72 dB and 78 dB) is technically a four-fold increase in compressor sound when rating air conditioners or heat pump units. However, it takes a difference of 10 decibels to double the loudness. It is also noted that it takes approximately 3 decibels for the average human ear to discern any difference in loudness at all. In many cases, the sound rating isn't as significant a determiner of sound difference to listeners as is the sound characteristics or quality. One type of sound with a lower sound power rating may be more offensive to a homeowner than another with a higher sound power rating. There are other important considerations, such as location, when considering the effects of sound. Our overall product line offers homeowners significant choices.

How much will my new air conditioning & heating system cost?
That depends. There are many factors that must be considered. These include:

The efficiency of the equipment
The size of your home
Is the ductwork installed and in good condition?
Do you need a thermostat or electronic air cleaner?

In most cases, replacing your whole system, including both indoor and outdoor components, will result in a more efficient, longer-lasting system but will also cost a little more.

Will anything help control the humidity in my house?
Humidity is a problem in many areas. The best way to control excessive humidity is to have a system that runs longer at lower speeds. Variable-speed air-handling equipment runs at very low speeds, which keeps the air circulating against the cooling coil and removes much more moisture than conventional systems. At these low speeds, the variable-speed motor also uses much less electricity than conventional motors. A two-stage outdoor air conditioning unit will operate at a low speed, removing more moisture and allowing greater comfort than a single-stage air conditioning unit. Some variable-speed indoor blower units have Enhanced Mode that runs a very cold coil and enables the blower to slowly ramp up and down. This will wring-out extra moisture from the indoor air.

What is a "ton" of air conditioning?
The air conditioning term "ton" equates to 12,000 BTUH (British Thermal Units per Hour). A 3 ton air conditioner is capable of removing a combined sensible and latent (humidity) load of 36,000 BTUH per hour (3 x 12,000).

Will a 18 SEER unit cool better than a 10 SEER unit?
The capacity of an air conditioner should not be confused with the efficiency rating. New units of like capacity (tonnage) cool equally as well regardless of efficiency rating. However, the unit with the higher efficiency rating uses less electricity.

My old A/C unit has not performed well the last couple of years. Do I need a bigger A/C unit?
Air conditioning units are like automobiles. They don't get the same gas mileage after 15 or 20 years of use. The majority of people who replace their air conditioning units with the same capacity unit experience a noticeable difference in comfort levels due to the fact the system is new and providing the full capacity for which it was designed. Unless changes have occurred in your home such as a room addition, the addition of skylights, etc., upsizing is rarely necessary. Occasionally air conditioners can be downsized if additional insulation or storm windows have been added. It's always best to have a professional make an on-site visit to determine the exact requirements of your home.

How do I know how much air conditioning and heating I need?
Be careful using any rule of thumb method to determine the capacity requirement for your home. Under-sized equipment obviously will not keep your home comfortable during peak cooling demand times, and over-sized equipment could be more expensive to operate and cause problems of high humidity. All manufacturers and HVAC experts agree the only way to determine the size air conditioner you need is by using a formula called a "load calculation". Magic Touch will be happy to come to your home or office and using the latest computer software on the market, perform a load calculation.

What is Carbon Monoxide?
Carbon Monoxide (CO) is a toxic gas that is odorless, colorless, and tasteless. You can feel the effects of CO and not even be aware of what the cause is until it is too late. Carbon Monoxide in its mild form is often mistaken to the flu with symptoms.These symptoms can include dizziness,headaches, nausea, fatigue and disorientation. The effects of CO exposure can vary from person to person. Overall health, age, and the concentration and length of exposure.

Where does Carbon Monoxide come from?
Carbon Monoxide comes from many different sources. Back drafting from furnaces, gas water heaters, wood stoves, and fireplaces; gas stoves, unvented kerosene and gas space heaters; leaking chimneys and furnaces; automobile exhaust from attached garages; and tobacco smoke. Magic Touch Mechanical believes any home with an attached garage and/or gas appliances should have a Carbon Monoxide Detector in the house.

How often should I have my HVAC equipment serviced?
Heating and Air Conditioning equipment should be serviced at least once a year. The best scenario is to have the heating system checked in the Fall and the air conditioning checked in the Spring. Gas-fired equipment should definitely be cleaned and serviced annually.

Why should I have my HVAC equipment serviced?
Annual servicing includes cleaning the system, checking for any problems or potential problems and adjusting for Peak Efficiency. The benefits include:

Increased dependability
Find potential problems and fix them quickly
Provide maximum efficiency which lowers energy costs
Prolongs the life-span of the equipment
Maintains safe and healthy operation
Can help to protect the environment

Drastically reduces the chance of a break-down which usually happens at night or on weekends when repair rates are higher.

What services need to be performed for preventative maintenance on my heating and air conditioning equipment? How often should this maintenance be performed?
We recommend you have us perform preventative maintenance before the winter heating season and before the summer cooling season. We offer comfort savingplans(CSP) that include reduced rates on labor and parts and provide priority response. CSP’s include washing outdoor coils if accessible, tightening electrical connections, checking supply voltage and operating current, checking refrigerant charge, measuring temperature differential at supply and return registers, cleaning blower wheel and motor, inspecting and adjusting burner, checking heat exchangers, cleaning drain lines and pan, checking ductwork for leaks and insulation, and checking thermostat.

Should I cover my outdoor condensing unit in the winter?
Covering the unit is not necessary. Air conditioners are manufactured to withstand all possible climate changes. In fact, rain helps keep your unit clean. Of course, because heat pumps run all year long, they should never be covered.

How close to the outdoor condenser should I plant shrubs or flowers?
Manufacturers generally agree that plants should not be closer than 18 inches. Air conditioners need intake and exhaust air to operate efficiently. If air cannot circulate, the unit could build up heat and require service.

What are the average life expectancies for heating and air conditioning equipment?
The average expected life of an air conditioner is approximately 15 years. The average expected life of a heat pump is approximately 10 to 12 years, since it operates year round. The average expected life of a gas furnace or air handler may be longer. Units in corrosive environments, such as, but not limited to coastal installations, will tend to have shorter lives.

Is there any advantage to setting my thermostat fan to "ON" so the fan runs constantly?
Yes, there are a couple of advantages. The first is that you get constant filtering of the air in your home. The second is that because the air is moving, you have a more even temperature throughout the home. However, continuous fan mode during COOLING operation may not be appropriate in humid climates. If the indoor air exceeds 60% humidity or simply feels uncomfortably humid, it is recommended that the fan be used in AUTO mode.

I've heard a lot about new refrigerants. Do I need to think about them when buying a system?
As of January 2010, the refrigerant “R-22” commonly called Freon was banned from being manufactured as the Environmental Protection Agency labeled it an “ozone-depleting chemical”. The replacement refrigerant now being manufactured is called R-410A also sometimes referred to as Puron. Our highly trained and experienced Installation Specialists are well versed in the considerations you should take into account when considering replacing your HVAC system and will be happy to help you determine what is the best choice for your home.

Why do my lights flicker when my air conditioner turns on?
Light flicker associated with the starting of appliances usually does not pose any safety problems and does not damage appliances. Proper wire connections and grounding are necessary to reduce flicker. Contractors and homeowners should check with their local utility regarding the appropriate wire size and transformer servicing the home. In cases where light dimming is related to the starting of a central air conditioner, and the previously discussed steps have not resolved the situation, HVAC manufacturers offer a device known as a start assist kit that can be purchased, which may help reduce flicker. Please contact us for assistance.

What is the difference between a Manufacturer's Limited Warranty and an Extended parts and labor Warranty?
A limited warranty covers specific parts (i.e. compressor, coil, electronics, etc.); therefore, the warranty language limits it. Extended warranties are generally purchased in addition to the limited warranty. Extended warranties cover all parts and may also include the labor for the service call. An extended warranty protects you from unexpected and unbudgeted service calls for the duration of the warranty.

CUSTOMIZE YOUR SYSTEM

What is a load calculation and why is it so important?
A load calculation determines what the proper size system is for your specific home. It factors in a number of criteria used to determine what size components you should include as part of your total comfort system, things like square footage, number of windows, and year-round weather concerns. A load calculation is important so that your system operates at maximum efficiency, with optimum performance. Most homes have systems that are oversized, so you end up paying more than you should to heat and cool your home. Also, systems that are improperly sized tend to cycle too quickly or too slowly, and that can lead to maintenance problems, uneven temperatures, and an inability to control humidity. A properly sized system based on a correct load calculation can help ensure you enjoy long-lasting, reliable comfort whatever the season.

What size system do I need for my home?
It is important that new or replacement equipment is not sized by "Rule of Thumb" or by duplicating the existing equipment capacity. The only accurate way to determine the correct capacity of heating and air conditioning equipment for your home is to have a load calculation performed on your home. There is a specific method to do this calculation. This will give the heat gain and heat loss design data for your home. These figures can then be used to select the appropriately sized air conditioning or heating system for your home, based on equipment-performance data. Many factors determine the size (capacity) system your home requires. Some of these are:

square feet to be cooled and heated, climate, humidity, number of windows, insulation factors, which direction your home faces, heat producing appliances, and the number of people who will be in the home.
Oversized air conditioning systems will not remove adequate moisture from the indoor air due to short cycling. Also, oversized systems quickly cool the indoor air temperature, but they do not run long enough to remove the humidity. That leaves you feeling stuffy and uncomfortable. Control of your home's climate is rarely achieved with oversized systems and electricity consumption is higher than with a properly sized system. An oversized furnace is similar to an oversized air conditioning system. The furnace run time is short, creating uncomfortable air stratification and less air filtration. Also, the frequent cycling of the unit on and off can cause undue wear and tear on internal working components. An undersized air conditioning system will not adequately cool your home on the hottest days and an undersized furnace will not adequately heat your house on the coldest days. Contact us for a load calculation on your home and a recommendation of the best system to meet your family's needs.

How do I verify the size of my air conditioner or heat pump?
The capacity in tons of a Trane outdoor unit can be determined by dividing the 7th and 8th digit of the model number by 12. So if the model number is 4TTX4036A1000A, take 36 and divide by 12, equaling 3 tons. This is only for Trane models. Other companies use a different method based on their model number nomenclature.

How do I find out about promotional programs or specials on equipment?

Do you provide financing options for equipment purchases?
Yes. We are able to assist you in finding consumer financing through several lenders and programs. We can also help you find seasonal promotions from the manufacturers, utility companies, and rebate programs. Please contact us for specific information about the current financing options available.

How much will my new system cost?
That depends. There are many factors that must be considered. These include:

The efficiency of the equipment
The size of your home
Is the ductwork installed and in good condition?
Do you need a thermostat or electronic air cleaner?

In most cases, replacing your whole system, including both indoor and outdoor components, will result in a more efficient, longer-lasting system but will also cost a little more.

The air coming from the registers feels cool when my new heat pump is set for heating. Is there a problem?
While a heat pump is perfectly capable of effectively heating your home, the temperature of the air coming out of the registers confuses some people. The air is heated to about 90 to 95 degrees, depending on the outdoor temperature. This temperature is approximately 20 to 25 degrees warmer than the indoor air temperature and will warm your house. It is, however, below body temperature (98.6 degrees) and can feel cool when someone puts their hand in the airflow.

What is a hot surface igniter?
Unlike older-model gas furnaces that used a standing pilot light to ignite the burners on the furnace, many of today's models use an electronic ignition system. This includes a Hot Surface Igniter, sometimes referred to as a glow plug or glow stick. When there is a call for heat, the igniter receives electrical current in order to heat its surface and ignite the burners in the furnace. Some hot surface igniters are fairly fragile and can be damaged during transit or installation. Cracks in a hot surface igniter are not necessarily visible. After installation, the glow pattern should be checked by your local independent dealer for inconsistencies, and replaced if necessary. Cracks will not necessarily prevent the igniter from working, but will shorten its life. It is important that the correct original equipment manufacturers igniter be used when replacing an igniter. There are many igniters on the market. However, many do not have the correct voltage or warm-up time as the original design.

What are the differences in single-stage, 2-Stage, and variable-speed gas furnaces?
A single stage furnace will deliver the same amount of heat and airflow no matter what the temperature is outside. A 2-stage furnace with a 2-stage thermostat will begin in first stage (low burner, low airflow) and only go to second stage if the indoor temperature drops during first stage. This makes the furnace run longer, providing greater air circulation, temperature distribution, and air filtration. This also provides a more consistent indoor environment. The second stage will only come on when the need is there and then it will be able to run longer and maintain the comfort level. The more your system starts and stops, the less control you will have of your home's environment - and the less efficiently it works, partly due to duct heat loss.

How does two-stage cooling work?
Two-Stage Cooling Offers Efficiency, Extra Comfort. If you are looking for energy efficiency and extra comfort in air conditioning, try a system with two-stage cooling. Two-stage cooling allows the air-conditioners compressor to run at high or low levels. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and produces more even temperatures.

What is an air handler?
The major components enclosed in an air handler's cabinetry are the blower and motor, controls, heater compartment, and an evaporator coil. This is why it is also sometimes referred to as a fan coil. A standard air handler, like the single stage furnace, delivers the same amount of airflow no matter what the temperature inside. A variable-speed Motor allows the coil to cool down quickly and the blower to slowly ramp up and ramp down or to operate at 50 percent of the cooling air speed in the FAN ON position. This provides greater humidity control, quieter operation, maximum air circulation, temperature distribution, and air filtration for greater control of your home's indoor environment.

I am interested in a programmable thermostat for my home comfort system. What thermostat should I select?
We will be happy to help you find the right programmable thermostat for your application, budget and desired features. Please contact us for assistance with purchase and installation of energy-saving controls.

What is a heat pump?
The heat pump is an air conditioner that reverses the process of removing heat from the inside of the house in summer to absorbing the heat from outside air and moving it inside in winter. It is effective by itself down to temperatures around 25 to 30 degrees Fahrenheit. At that point, either a gas furnace or an air handler with supplemental electric heat will kick in and help heat your home. The Auxiliary Heat light on your thermostat will light. The heat pump will continue to operate along with the electric auxiliary heat. It will shut off when a gas furnace is energized. Emergency heat is a manual override option in the event your heat pump needs service.

What is the purpose of auxiliary heat?
Under normal operating conditions, the auxiliary heat is brought on automatically by the thermostat when the indoor temperature drops during heat pump operation. There are also times during cold, wet weather when the outdoor coil may ice up and your heat pump will go into a defrost cycle. This is nothing more than reversing the process back to cooling mode. Cooling mode makes the outdoor coil hot and melts any ice. The defrost cycle should only last a few minutes and then return to heating mode. During the defrost cycle, your comfort system is in cooling mode and the supply air is cool. To offset this cool air, the auxiliary heat will be energized during defrost. A mist or fog may be visible from the outdoor unit during defrost.

Is a heat pump the right choice for my home?
The heat pump is very effective in our Arizona climate. In all electric applications, the heat pump may consume less energy than an electric furnace or air handler using resistance heat. Why? Because it can deliver the same amount of BTUs as electric heaters using less electrical input than the electric heat. In moderate climates the savings that natural gas yields may not be as advantageous as in colder climates, since there is less frequent use of the furnace in milder climates. Of course, the heat pump can be matched with a gas furnace where preferred, this is referred to as a “dual-fuel system” or a “hybrid system” and gives you the best of both worlds.The heat pump can operate in milder temperatures when the gas furnace may tend to short-cycle (keep turning on and off quickly).

FOR LENNOX OWNERS

What is the best indoor air quality product?
The Dave Lennox Signature™ Collection PureAir™ air purification system cleans the air better than any other single system you can buy. It's the only indoor air quality product that removes all three sources of contaminants (particles, bio-aerosols and odors). It's also the only product that combines air filtration and purification capabilities into one integrated system.

How does the PureAir™ air purification system work?
The PureAir system reduces concentrations of pollutants through a process called photo-catalytic-oxidation (PCO). Similar to the process used by the Department of Defense to combat germ warfare, PCO combines nature's three most powerful air purifiers:

Ultraviolet light
Titanium dioxide, a nontoxic substance found in the earth's crust
Hydroxyl radicals, particles derived from hydrogen peroxide

The PureAir PCO process involves three steps:

The pleated media filter captures particles and bioaerosols like pollen and pet dander, removing them from the airstream.
As the odor- and chemical-filled airstream flows over the UVA light, the airstream is exposed to the catalytic surface (titanium dioxide-coated mesh filter).
The light energy activates the catalyst, which generates hydroxyl radicals. These particles, which are more than twice as powerful as chlorine, break down the odors and chemicals into carbon dioxide and water.

Does the PureAir produce ozone?
No, the PureAir does not produce ozone.(Ozone, is a product of pollution, is a known lung irritant. Existing respiratory conditions can be aggravated by high levels of ozone).
Many of today’s electronic air cleaners DO produce ozone and are even banned in certain states. Be sure to find out if the product you are looking at produces ozone.

What is Solar energy?
Solar power is an area of interest for many people who are concerned about the environment we live in. Solar-energy is an infinitely renewable resource that uses the sun’s rays to generate electricity for use in your home. By going solar, you can reduce your energy costs and also lower your dependence on fossil fuels, thereby making your own contribution to a cleaner environment.

How Does Solar Energy Work?
Solar power system technology has advanced a great deal since its beginnings due largely to demand.A residential solar-energy system uses solar modules, made up of photovoltaic (PV) cells, to harvest the sun’s energy and convert it into electricity that can be used to power your lights, appliances and other electrical devices in the home. To generate a useful amount of electricity, many of these cells are combined to create a solar panel.

What do terms like "on-grid" and "grid-tied" mean?
On-grid solar systems, also called "grid-tied" systems, are connected to the utility electrical network in your area. SunSource is an on-grid system designed to help you lower your utility operating costs and take advantage of incentives from utility companies. "Off-grid" refers to typically more expensive systems that are not connected to the utility electrical grid.

INDOOR AIR QUALITY (IAQ)

Why should I be worried about my air indoors?
We spend 90% of our time every day indoors. Plus, today's efficient, airtight homes are excellent at conserving energy, but that also makes them better at trapping potentially irritating particles inside the home. The EPA (Environmental Protection Agency) estimates that the exposure to pollutants in the air can normally be up to 5 times greater and on occasion 100 times greater indoors than outdoors. With the rising number of people who suffer from allergies and asthma, indoor air quality has become more and more important to our general health and well-being.

What kinds of things are in my home air that might be affecting my family's health and comfort?
Indoor contaminants derive from 3 different sources;

Particulates (Dust, Dust Mites, Lint, and Animal hair/dander)
Volatile Organic Compounds (VOCs) (Pet Orders, Perfume, smoke, Chlorine, Cleaning Supplies, Paints/Solvents)
Bio-aerosols (Bacteria, Mold Spores, Viruses)

For Better Health...
Contaminants in your Heating Ventilation Air Conditioning (HVAC) system can aggravate asthma and allergies. Our Duct Cleaning process can help eliminate bacteria and fungus to improve the air quality in your home. Cleaning your air ducts can protect everyone in your home from breathing contaminated air.

For A Cleaner Environment...
Less dust and dirt means a cleaner environment. Cleaning your air duct system can help maintain a cleaner home, requiring less dusting.

For Better Efficiency...
Cleaning your air duct system helps your HVAC system run more efficiently, resulting in less run time and lower heating and cooling bills. Cleaning your air duct system can also extend equipment life.

You Should Also Consider Having Your Ducts Cleaned If?
There is substantial visible mold growth inside sheet metal ductwork or on other components of your heating and cooling system.
Ducts are infested with vermin... rodents or insects.
Ducts are clogged with excessive amounts of dust and debris.
Particles and/or debris are actually released into the home from your supply registers or vents.

What kinds of things are in my home air that might be affecting my family's health and comfort?
Indoor contaminants derive from 3 different sources;

Particulates (Dust, Dust Mites, Lint, and Animal hair/dander)
Volatile Organic Compounds (VOCs) (Pet Orders, Perfume, smoke, Chlorine, Cleaning Supplies, Paints/Solvents)
Bio-aerosols (Bacteria, Mold Spores, Viruses)

What can I do to help make my home's air cleaner?
The best thing you can do is to remove as many of the particles from your home's air as you can, with an air filtration system. It works as part of your total home comfort system to remove up to 99.98% of the airborne allergens from your home's filtered air

WHOLE HOME ENERGY AUDIT

Whole home energy audit
The Whole Home Energy Audit is the most comprehensive and in-depthlook the home or business to effectively identify all areas that may be causingexcessively high energy bills. Magic Touch Mechanical’s comprehensive energy audit consists of a Blower Door Test, Duct Blaster Test, Air-Flow Test, Digital Still and Digital Infrared (Thermal Image) Pictures of Deficiencies, Comprehensive A/C and Heating System Analysis, Comprehensive Duct Design and Condition Analysis, and a Manual J load calculation.Individually, each one of these analysis and tests can benefit a homeowner by isolating a specific area of concern. But combine the Whole house energy assessment gives the homeowner the Big Picture on where energy dollars are being spent.

What is a Blower Door?
A blower door is a variable speed fan, mounted in a doorframe, used to pressurize and depressurize a house to measure air leakage. The blower door is connected to high-tech digital gauges that measure the amount of air pulled out or into the house by the fan. The calibrated blower door's data allows the auditor to quantify the amount of air leakage and the effectiveness of any air-sealing job. This determines the overall tightness of a building.

What is a Duct Blaster?
A duct blower is a variable speed fan that is attached a digital gauge and connected to a duct system to measure duct air leakage. Duct air tightness measurements are used to diagnose and demonstrate leakage problems, estimate efficiency losses from duct leakage, and certify the quality of duct system installation.

What is a Manometer?
A manometer is an instrument that measures the pressure differential between two locations,in this case, between the return air side and the supply air side of the furnace or air handler. We compare this static pressure reading to manufacturer specifications to assure optimalair flow and efficiency.

What is a Flow Hood?
A Flow Hood is a device used to measure the amount of air flowing through a register.

What is aInfrared Camera?
An infrared camera makes an image that shows surface heat variations that can be used to help detect heat losses and air leakage in buildings. The infrared camera is one of the best and most versatile “tools” that the auditor may use. Magic Touch places high value on it’s capabilities and we believe any energy auditor that is not using one to its fullest potential is falling far short in their job performance.
An infrared camera can simultaneously:

Locate and document air leaks
Detectdefects in the thermal boundary, insulation voids, insulation settling, thermal bypasses, etc.
Indentify and document phantom electrical loads.
Obtain the framing factor and other framing details.
Find areas of high moisture and water leaks.
Documentsimmediately, each energy wasting deficiency found both with an IR and visual light image.

What is Home Sealing?
Home sealing is a process for improving the "envelope" of the home. This includes the outer walls, ceiling, windows and floors. Air leakage from cracks and gaps throughout the home can equal as much air flow as leaving a window open all year long. These leaks force the heating and cooling equipment to work harder to keep your family comfortable and your energy bills are the proof.

Why is sealing the ductwork important?
For an average home, leaky ductwork often accounts for 10 to 30 percent (in extreme cases much more) of total heating and cooling costs. This is one reason for hundreds of dollars that are wastedon your utility bill each year. While the increase in energy cost is significant,protecting health and safety is the most important reason to seal ducts. Ducts are usually located in the attic, crawl space or basement. If the return ducts leak, they draw air from these areas directly into the home. This air can be contaminated with dust, mold, mildew, excess humidity, and potential toxins such as pesticides for termite treatment, combustion gases, and radon. On the other side when the supply ducts leak, they can create a lower pressure inside the house which draws in contaminates, also.

How do I know if a system has duct leaks?
Energy codes require that all joints in the ductwork be sealed. However, many leaks are not readily visible. Having one of our BPI Certified Building Analysts pressure test the ducts with a special fan is required ("Duct Blaster test"). The test involves temporarily taping over the registers, then blowing air into the ducts with the fan to determine the amount of leakage as well as the location of the leaks. The test takes approximately two hours.

AIR CONDITIONING

How much does an air conditioner cost?
Many different factors are included in determining the cost of an air conditioner. When you buy a car for example, you just pick your amenities and it’s ready to drive away. But when it comes to air conditioning, aside from the actual unit cost, you also need to have it installed properly. To determine the true actual cost of your new air conditioner, Magic Touch will provide you with a FREE estimate, with no obligation and no high-pressure sales tactics.

Can I get a quote over the phone?
There are many variables and choices when it comes to choosing the right HVAC system for your home or business. Every application is different and no contractor can give you a true estimate without seeing the application, measuring the home, and determining the proper tonnage by performing a load calculation. If you insist on a phone-only quote, we will provide some broad numbers, but we cannot be held to a specific estimated number without conducting the proper site survey. Other companies may invite such bait-and-switch opportunities, but Magic Touch encourages you to take the time to get the estimate done properly, for everyone’s protection.

I’m looking to replace my air conditioning unit. How many bids should I get?
Typically we recommend bids from three certified, insured HVAC contractors. “Three” so you can determine high/low and averages. “Certified” so you know you are working with qualified experts. “Insured” so you know you won’t risk being left with unfinished or damaged work from a handyman or inferior company. Sometimes getting three bids for identical work with identical qualification requirements will be a good indicator of the kind of company you would be working with. It’s important to keep in mind that the installation is more important than the equipment chosen and if one company’s estimate is significantly lower than others, you may not be receiving the same caliber of installation. Another important thing many customers neglect to do until it’s too late is check with the BBB and make sure the contractor has a good rating. It’s also a good idea to check consumer review sites like Kudzu.com and AngiesList.com to see what previous customers have to say about their experience with a contractor. Magic Touch has an A+ record with the BBB and is the highest rated HVAC contractor in Arizona on Kudzu.com and AngiesList.com

What’s the difference between a regular installation and an ENERGY STAR® rated qualified installation by Magic Touch?
A regular installation (or a change-out) is normally what people get when they go with the “lowest bid”. It includes equipment replacement and takes less than one day – after the installation the unit is turned on, the Freon levels are checked (hopefully), and the job is done. We typically have equipment installed and running in one day, but we do testing that sometimes requires another day. That’s because Magic Touch follows recommended industry standards by the Air Conditioning Contractors of America and Building Performance Institute, starting with load calculations, and concluding with “test out” procedures. Most houses in Arizona deliver less than 60% of the cooling energy that’s being paid for in terms of BTUs. So rather than simply swap out equipment and wish you a good day, Magic Touch makes sure you have the right unit working at peak efficiency – because that will save you money every month for many years to come.

What does SEER stand for?
SEER stands for Seasonal Energy Efficiency Ratio. It indicates the efficiency of air conditioning systems. The higher the SEER number, the more cooling you get per unit of energy. As of January 2009, only units with a SEER of 13 or higher are allowed to be sold in the United States. Today's cooling units are up to 40% more efficient than those made as recently as 10 years ago. One way we define SEER is by comparing it to MPG (miles per gallon) of a car, same rules apply, the higher the number the more efficient it is. Magic Touch has won numerous awards from manufacturers like Trane and Lennox for installing more “high efficiency” equipment than any other contractor in Arizona. We have always believed in getting our clients the “best bang for their buck.”

Is it OK to “mix and match” air conditioning components of different efficiencies? Just because my compressor is on its way out, does it mean I have to replace my indoor unit as well?
It is never a good idea to mix and match A/C components of different SEER. You might save money initially by replacing only your outdoor unit with one of the new mandated 13 or higher SEER compressors and hooking it up to your 10 or 12 SEER system. However, it just doesn’t make sense in the long run. It is like buying a brand-new sound system and hooking it up to antiquated speakers. You're just not going to get your money’s worth in terms of performance. You are better off investing a little more now to do things right, because you will save much more on energy costs over time. In fact in most cases because of the different refrigerants being used now, it’s no longer even possible to just replace half the system.

My home has a forced-air furnace but no air conditioning. Can I add central air?
You bet!

My home does NOT have forced-air heating, and so there is no ductwork. Can I still get central air conditioning?
Absolutely! Today’s ductless air conditioning options make it possible for us to install a quiet, efficient air-conditioning system in your home even if it doesn't have ductwork. Ductless air-conditioning systems consist of one or more indoor air- distribution units linked by refrigeration lines to an outdoor compressor. Magic Touch can install these flexible “hoses” inside your walls and ceilings with a minimum of inconvenience. These installations cost a little more than standard central air-conditioning installations, but much less than installing ductwork and a central air-conditioner.

I’ve heard that they are phasing out the old A/C refrigerant in favor of a new, more environmentally friendly version.
That’s right. As of January 2010, cooling system manufacturers can no longer make equipment that uses R-22, commonly known as Freon. R-22 has been found to damage the Earth’s ozone layer, which is a key factor involved in global warming. The coolant that has replaced R-22 is known as R-410A, which was developed by the Allied Signal company in 1991. Several companies have since trademarked their own version of R-410A, including Carrier (Puron®), Honeywell (Genetron® AZ20) and Dupont (Suva® 410A). Years of commercial use and testing have proven that, in addition to being more environmentally friendly, R- 410A also offers superior performance and energy efficiency versus Freon.

Why does it cost so much to run an air conditioning system?
Air conditioners run on electricity, and electricity is the most expensive energy source because converting fuels like coal or natural gas into electricity is inherently inefficient. What’s more, much of the original electricity generated by a power plant is lost during its transmission over power lines. (According to the U.S. Department of Energy, by the time it reaches your home, electricity is only 33% efficient, on average.)

The good news is that today’s air conditioning systems are much more energy efficient than they once were, and things are improving all the time. To further increase your air conditioner’s efficiency, you should also consider room design – if your A/C system is not meeting the cooling needs of your home, it will run less efficiently and work harder than it should. That’s why Magic Touch takes great care in determining a room’s or home’s load requirements when recommending any air conditioning equipment you may need.

Do I really need a tune-up for my air conditioner?
An air conditioning tune-up and inspection will help catch service problems before they get you hot under the collar with major expenses. Many breakdowns occur on the hottest day of the year, because that’s when your A/C is under the most stress. And because a tune-up ensures that your system will run at peak efficiency, you will enjoy lower electric bills. In fact, a properly running air conditioning system can save you up to 30% on your cooling costs. So give us a call to schedule your annual tune up today!

WATER HEATERS

What can I do to maintain my water heater?
You will get longer life from your water heater and prevent breakdowns if you follow these simple guidelines:

Drain a gallon of water from the tank every three months – do it every month if you have hard water. This reduces the amount of sediment collecting in the bottom of the tank, which can make the burner or heating coils work harder.
Have your water heater inspected by a Magic Touch service technician every year to keep it in peak operating condition.

SERVICE

How long do Magic Touch customers have to wait for emergency service?
Members of our Comfort Savings Club receive priority scheduling, guaranteed service within 24 hours even on the hottest days of summer and usually MUCH quicker than that!

Do you use your own installation specialists or do you hire subcontractors?
We use only our own certified, factory-trained technicians. We never hire subcontractors. Our technicians are the most highly trained in the industry. To use subcontractors would be like taking a step down. Your comfort and our reputation are too important to put in anyone else's hands.

How long does it take to get an estimate?
In most cases we can arrive the same day but usually no more than a matter of a couple of days. We can come out to your home at your convenience during the day or in the evening. To recommend the right size system for you, we do a lot of calculations. We pay particular attention to your room’s or home’s load requirements, to ensure that the system we estimate for you will run at peak efficiency – which maximizes system life and reduces your monthly energy bills.

Approximately how long does it take you to complete an installation of an air conditioning or heating system?
Every job is different and some take longer than others. Depending on the application, many jobs can be completed in one day, others can take two days. Our Comfort Consultant will know with pretty high accuracy how long your job will take to complete and let you know when giving you your proposal.

Do you offer maintenance plans?
Yes we do. For complete information, click here.

Is annual maintenance necessary?
Yes! In our area, air conditioning systems work very hard. When anything is operating virtually non-stop for months on end, it needs regular maintenance – just like your car. Without the regular maintenance of a tune-up, you lose efficiency and money every single month.

Annual tune-ups keep your system working at peak efficiency and give our technicians a chance to catch minor problems and signs of wear before they turn into major trouble down the road. Many warranties now require annual tune-ups to qualify for coverage. An annual tune-up helps protect your family against carbon monoxide poisoning. And regular maintenance can help extend the life of your equipment.

How do I know what size system to install?
Don’t worry, the experts at Magic Touch will be happy to come to your home and calculate your home’s cooling and heating “loads.” Our Comfort Consultants carry laptops and have been well trained in completing a computer generated load calculations. We will then be able to recommend a system that is the correct size and model to meet your home’s requirements. Please call us for more details.

Does Magic Touch do electrical work?
Any and all electrical work pertaining to HVAC. We also have partner company’s that we can arrange to estimate other electrical work you need or would like to have done. Magic Touch President; Rich Morgan serves on the Board of Directors for the Arizona Electric League (SRP & APS), and is the current Vice President of the AZ Chapter of the Air Conditioning Contractors of America.

REPLACE OR REPAIR

How do I know if it is more cost-efficient to repair my old air conditioning system or replace it?
If you’re like many people, the frustration of an equipment breakdown can make it tempting to solve the problem with a quick fix that doesn’t cost you a lot of money. That way you can get on with your busy life in relative comfort. But while a quick fix may be the least expensive solution in the short run, it may not give you the most value in the long run.

It's a fact of life: Older systems are more likely to break down. That means a bigger chance of emergency service calls and repairs – and paying for them.

There is also an ongoing cost factor. Repairing an old system can only restore it to something less than its original level of efficiency. After you've recovered from the repair bill and the frustration of a system breakdown, you will still be battling high energy bills. What’s more, even a system that doesn’t break down loses efficiency as it ages. A 15-year-old system doesn’t operate anywhere near the efficiency it had when it was new!

When compared with modern, technologically advanced equipment, 15-year-old cooling systems are considered inefficient by today's standards. The average homeowner can save up to 40%, more in some cases, on cooling costs with new high-efficiency equipment.

Here are some rules of thumb to help you decide whether to replace or repair.

Replace your system if:

It is more than 10 years old and only in average condition
It does not keep you as comfortable as you would like
It breaks down frequently
You will be living in your home for at least five more years

Repair your system if:

It is less than 10 years old and in good condition
Your cooling costs have been acceptable
You are pleased with your level of comfort
Its performance is reliable
You will be moving within the next five years
It is still under warranty

HEATING

What should I do if my heating system doesn’t work?
Before you call or e-mail us, go through the troubleshooting steps below to make sure a service call is really needed. It will save you the cost and inconvenience of an unnecessary service visit, and will ensure our technicians are working where they are most needed.

Make sure the thermostat is set above room temperature or in the “heat” position. If it is a digital thermostat and the display screen is blank, you either need new batteries or the power supply has been interrupted.
Check for a tripped circuit breaker or a blown fuse.
Look to see if the power switch for your heating system is turned on.
Sometimes, these get turned off accidentally.
If you have natural gas heating, make sure the gas valve is in the on position.
If you have a heat pump system, wait 15-20 minutes to make sure the unit is not in the “defrost” mode.

If at this point you still don’t get heat, call Magic Touch immediately.

When our service technician arrives, let him know everything you did to the system before he begins working on it. You should also let him know if anything out of the ordinary happened, like an unusual noise, a strange smell or smoke. In many cases, this will help our technician find the problem – and get your heat back on again – faster.

How does a furnace work?
A furnace generates heat burning natural gas or propane. This happens in the combustion chamber, which gets very hot. Air absorbs this heat in the furnace’s heat exchanger. Next, the blower sends the heated air through a system of ducts, and warm air circulates through the home.

What is a cracked heat exchanger?
The heat exchanger is the main component of your furnace. If the heat exchanger has a crack or a rust hole, combustion fumes (including carbon monoxide) can contaminate the air in your home. This is a potentially deadly situation and should be addressed IMMEDIATELY. A cracked heat exchanger usually requires replacing the entire furnace. If you suspect that you might have a cracked heat exchanger, or a carbon monoxide problem caused by your furnace, turn the system off immediately. Then call Magic Touch right away for service.

On mild winter days my furnace runs in short blasts and my home alternates from being too hot to being too cold. How can I fix this?
Installing a new furnace with a variable speed motor is a good solution. These “smart” motors automatically adjust the volume and speed of air based on your home’s temperature requirements. There will be fewer on/off cycles, smaller temperature swings, consistently even heat, and lower fuel bills.

I hear a lot of talk about high-efficiency heating systems. How do you determine a heating system’s efficiency?
All heating equipment manufactured after 1980 has been required to have a label indicating its AFUE. The AFUE ratio is a measurement of a heating system’s seasonal efficiency, taking into account how well the system performs over an entire season of starts and stops. Modern heating systems can range in efficiency from 81% to 97%. If your system’s AFUE is lower than this range, ask us about your replacement options.

At what temperature should I set my thermostat?
Different people feel comfortable at different temperatures. Pay less attention to the number on the thermostat display (or the position of the temperature indicator on a non-digital display) and more to how comfortable the room feels to you. When you feel comfortable, check the setting. That's the right temperature for you. Having said that, you may want to test dropping the temperature a degree or two and see how that feels. The lower your temperature setting, the more you will save in energy expenses each month.

What does (lo-bat) on the thermostat mean?
This means the battery is almost dead should be replaced immediately.

Should I have Magic Touch install a programmable thermostat?
Absolutely! Programmable thermostats are especially useful for people who are away from home at regular intervals. They allow customized comfort settings around the clock, and they can cut heating and cooling costs by as much as 10%!

My thermostat is suddenly reading Celsius. What can I do?
Either find your owner’s manual to get it back to Fahrenheit, or call us to help you out. Some of the older models will read Celsius if you accidentally push two buttons by mistake.
