|Frequently Asked Questions|
On really hot days, my house never really seems to cool properly with the system I have now. Can I increase the size of my AC to help this problem?
More is not always better.
Incorrectly sized equipment can lead to operation and cost
problems. Oversized air conditioning systems can
“short-cycle” leading to rapid cooling without reducing
indoor humidity levels. This can lead to a variety of
problems associated with high relative humidity. Since the
humidity is not being pulled from the air in your house, you
are still going to feel uncomfortable. A variety of
variables determine the size you need. You should have
a technician determine the correct size you need for your
Yes! If you properly maintain your system you should be able to extend the life of your system as well as increase the efficiency of your system. Regular maintenance of your system will reduce the amount of breakdowns your equipment will have. Remember the #1 cause of major breakdowns are caused by a lack of maintenance.
Do programmable setback thermostats really save you money?
Yes! Using a programmable setback thermostat can reduce your operating expenses by up to 30%.
Do we need to change filters each month?
Absolutely! In addition to using more electricity and reducing the performance of your system, a dirty filter can also cause your air conditioner to 'ice up' due to restricted airflow across the indoor coil. Continuing to run your air conditioner once it has iced up can lead to a number of other problems, including compressor failure.
What is a good temperature to set my thermostat on?
Most of the time, the best setting is just where you are comfortable! However, when those extremely high summertime temperatures set in, your best temperature setting is going to be 15 to 16 degrees below the outside temperature. Remember, your air conditioner can only produce so much cooling, no matter how low you set that thermostat. And no matter what temperature you choose, once you have found a 'comfort zone' leave that thermostat set in one place - turning it up and down constantly only costs you more energy!
My indoor unit is leaking water.
Most of the time, this is caused by a
plugged drain line. Water then backs up into the drain pan
located inside the unit until it overflows. Leaks may also
be caused by a crack or hole in the drain pan.
My outdoor unit makes strange noises.
Those annoying noises can be caused by
something as simple as a loose bolt or screw, or they can
indicate something as serious as bad bearings in the motor.
If you are a do-it-yourself homeowner, remember to always
turn the power off to the outdoor unit before you start
checking bolts or oiling motors, etc. Also, some motors are
not made to be oiled - once the bearings start making noise,
the only thing to do is replace the motor. Don't wait too
long; if those bearings seize up, the compressor can be
My pilot light keeps going out.
Although this could indicate a problem with your gas valve, most of the time it indicates a weak or defective pilot thermocouple. The thermocouple generates an extremely low electrical current (measured in millivolts!) that allows the gas valve to feed the pilot flame. When the thermocouple becomes weak it means the gas valve will not allow gas to go to the pilot assembly. If you have to relight a pilot more than once, a service technician should check the unit.
Are there any advantages to using the fan’s “On” setting versus the “Auto” setting on my thermostat?
Switching your fan into the “on” position
provides several benefits that may not be immediately
obvious to many homeowners. The first benefit is continuous
filtration. As the air circulates through your system, it is
constantly being passed through your filters. As a result,
the quality of the air in your home improves.
I have a new air conditioning system but it's still too hot upstairs. Is this normal? Is there anything I can do about it?
This is a common problem with two story
homes that were built without zone controls (separate
thermostats for upstairs and downstairs). The best way to
solve the problem is to adapt a new zone control system to
the home. Short of doing that one thing that you can do to
help but not solve the problem is to run the blower
continuously. This helps to mix the upstairs air and
downstairs air and brings the temperature closer to being
Is there any real difference between brand names of air conditioners?
Yes. There are major differences. We use only Trane air conditioners because they use all aluminum condenser coils (other brands use copper tubing with aluminum fins and the SEER rating of these type of units degrade rapidly after installation), they build their own compressors which have an extremely low failure rate, at last count less that one half of one percent came back to the factory with a problem and half of those were misdiagnosed, and this manufacturer provides a steel louvered cabinet around the entire unit to protect the condenser coils where other manufacturers leave the coils exposed to damage.
