system will not run at all, what do you
The most common reason that a system will not run is because of a loss
power. In most every situation an air conditioning system is protected electrically by a
or fuse which is located somewhere in the power supply lines upstream from both the air handler
This breaker is designed to provide over current protection and prevent
electrical damage to your equipment.
Find this breaker, turn it completely "off" even if it appears to be
then turn it back on again. If it trips again, leave it alone and call your contractor.
The second most common reason for a system not to respond when called
is problems in the low voltage (24v) control circuit. This circuit is comprised
controllers and relays that send signals to the components in your system to perform specific functions
heating, cooling and fan
The most common problems are found in the thermostat connections and
failure of the transformer. If you are mechanically inclined, you can change
thermostat yourself in most cases because the various wires coming to your thermostat are color
and you simply hook up the appropriate color wire to
the terminal for that color on the thermostat.
And, don't forget! Dirt
is the biggest enemy of your air conditioner!
Giving your air
conditioning system an efficient, high MERV rating air filter is
the best thing you can do for your air conditioner. A good air filter will
extend the life of
conditioner because the important parts, like the blower assembly, the cooling
coil, and other inner parts will stay cleaner, operate more
And, as a side benefit of having a good air filter,
your family and you
will enjoy breathing much healthier indoor air. Air
that will be free of dust mites, mold, mildew, dust, pet dander, etc.
