Why does my air handler freeze up? The most common reasons for your air handler freezing up is due to dirty filters or dirty coil, low refrigerant charge-possibly due to a leak, or operating the system in cooling when outside temperature is below 70 degrees.  Back To The Top

Why does my indoor fan run continuously and never cycle off? Check your thermostat setting and make sure that the fan is set in the “Auto” position and not in the “On” position. This will cause your indoor fan to come on only when called by the thermostat for cooling or heating. . Sometimes the setting gets bumped accidentally into the “On” position. If this is not the case, then you should call for service.  Back To The Top

Why doesn’t the fan on my outside unit come on? You should first make sure that there is power to the outside unit. When your thermostat is set and the unit should be coming on, go outside and listen for a humming noise. If you hear no noise, then you probably have no power to the unit. Check the power disconnect outside at the unit (if breaker type, flip off then on again; if fuse type, pull out then push back in), then check the breaker inside at the breaker panel. If this does not bring on the unit then you should call for service.   Back To The Top

Why should I replace the entire system rather than one component? it’s actually more cost-effective in the long run to replace the entire system rather than just one part because the air conditioning components are designed to work together as matched systems. Otherwise, if you replace just one component you may not be receiving the rating of the piece of equipment you have just installed. It becomes just a guess on how efficient your system will perform. A complete system ensures that you are getting the SEER (efficiency) that you purchased.

When should I repair or replace? If your system is 10 years or older and the system needs frequent repairs, or your system has had a major component failure, high electric bills or the unit is not cooling like it used to then you should consider replacing the system with a new, reliable efficient system.  Back To The Top

What are the advantages of Two-speed Air Conditioners? Two-speed units can run on low speed (using 50% of the energy) up to 80% of the time, so they offer fewer on/off cycles, and smaller temperature swings. You also get better air circulation, for even, consistent cooling and/or heating throughout your home. Plus, if you purchase a variable speed air handler with you unit, you will enhance both the comfort and efficiency of your air conditioning or heat pump system even further. Back To The Top

Why should indoor air quality be of concern? Environmental Protection Agency studies have shown that the air inside our homes and workplaces is 10-100 times more polluted that outside air. Harmful airborne pollutants such as dust, pollen, mold viruses, bacteria, pet dander, carpet fibers, and second-hand smoke are constantly being re-circulate and inhaled while indoors. According to the EPA, a person breathes in 2 teaspoons of these pollutants each day, This can result in harmful health conditions such as allergies, asthma, and other respiratory problems.  Back To The Top

When should a Humidistat be installed? If you leave your home or condo for more than 4 weeks at a time then a Humidistat is a good investment since it will save money of your electric bill. Back To The Top

When should a heat recovery unit be installed? It is recommended if you have a system with R410 refrigerant or equivalent. The pressures that normally occur with this refrigerant produce enough heat to suit your family’s hot water needs without using additional energy.

What is happening with refrigerants in air conditioning systems? The current refrigerant used in air conditioning systems is called R-22. Due to suspected ozone depletion, EPA regulators call for the eventual phase out of this refrigerant. Equipment that uses R-22 must stop being produced by the year 2010. All production of R-22 will stop being produced by the year 2020. There will be sufficient supplies of R-22 to service the equipment for its life span. Sufficient quantities of R-22 will continue until 2020. After 2020, recycled refrigerants will be available, for many years, which will safely fulfill all service needs for products that use R-22. The apparent refrigerant of choice to replace R-22 is known as R410A. R410A & Puron are both the same refrigerant currently being manufactured by the same company- Allied Signal. Over the next several years you will see more prevalence of R410A. Back To The Top

At what temperature should my thermostat be set? During the cooling season, most homeowners keep their thermostat set between 76-78 degrees. During the heating season, most homeowners keep their thermostat set between 68-72 degrees. Any setting will work, but please keep in mind that varying from these settings will effect your utility bills.
