How often should I change or clean my filters?
Filters should generally be replaced every month when the system
is running. Replace filters with the same kind and size as
original filter. If your filter is not disposable, follow the
manufacturer instructions for cleaning.
Is there any advantage to setting my thermostat fan to "ON"
so the fan runs constantly?
Yes, there are a couple. One is that you get constant filtering
of the air in your home. The other is that because the air is
moving, you have a more even temperature throughout.
Should I cover my outdoor 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 unit should I plant shrubs or flowers?
Manufacturers generally agree that plants should not be closer
than 18 inches. Air conditioners need to take in and exhaust air
to operate efficiently. If air cannot circulate, the unit could
build up heat and require service.
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 uses much less
electricity than conventional motors.
I need a new outdoor unit, but my indoor unit works fine. What
are the advantages of replacing my whole system at the same
We recommend that you 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 size system do I need for my home?
There are many things which will determine the size (capacity)
system your home requires. Some of these are: square feet to be
cooled, climate, humidity, number of windows, insulation
factors, which direction your home faces, heat producing
appliances, and even the number of people who will be in the
home. We can do an energy analysis on your home and help you
decide what your particular needs are for your lifestyle.
How do I find a dealer who will do a good job?
Ask people you know who have had an air conditioning system
installed , and if they would recommend them. Check with the
Better Business Bureau. Have the dealer come out and give you an
estimate--see how they handle their customers. Ask for
references--and then check them.
How much will my new air conditioning system cost?
That depends. There are many factors that must be considered.
- 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, indoor and outdoor
components, will result in a more efficient, longer lasting
system but will also cost a little more.

What is the difference in 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, it is limited by the language in
the warranty. Extended warranties are generally purchased in
addition to the equipment. 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.
I've heard a lot about new refrigerants. Do I need to think
about them when buying a system?
We do not advise homeowners to choose home comfort systems based
on the refrigerant they use. The Clean Air Act does not allow
ANY refrigerants to be vented into the atmosphere. They must be
reclaimed, recycled and reused. Units using the current
refrigerant, R-22, will always be serviced with R-22. They will
not need to be changed to a different refrigerant. The scheduled
phase-out of R-22 allows for plenty of refrigerant to be
available to service all cooling units and heat pumps that use
R-22 for the life of the equipment. We do offer limited lines of
high efficiency comfort systems using R-410A refrigerant. Our
gradual introduction of these products will allow servicers in
the field the opportunity to purchase new recover equipment and
service tools, as well as adapt to stricter installation and
service techniques, to ensure homeowners continue to receive the
comfort and value they have chosen.
As the HVAC industry gradually and confidently transitions to a
new refrigerant, we encourage homeowners to maintain their focus
on purchasing energy efficient home comfort products that best
meet their comfort needs. Purchasing higher efficiency cooling
and heating systems and better sealing our homes will not only
improve comfort and reduce energy costs, but will also improve
What do all those rating numbers mean to me?
The federal government requires all air conditioning and heating
equipment to be rated as to efficiency. The higher the rating,
the more efficient the model.
For cooling, the
rating is SEER (Seasonal Energy Efficiency Ratio). This rating
is based on general design criteria and does not reflect a
specific efficiency level for a specific application. SEER
ratings are for comparison purposes only so that homeowners will
know that 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 12 SEER. The
actual efficiency rating for a specific system will depend on
the combination of the outdoor unit, the indoor coil, and the
size of the system. These ratings are available to your dealer
in 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.
