The
system is running but the air is not very
cold, what's wrong?
If some cooling is taking place but not enough, then the chances are
that
the system is low on freon. The only reason a system would need freon is because the freon leaked
out.
If the leak is not sealed before recharging with freon, the freon will eventually leak out
again......
Leak repairs are expensive so if it's a small leak it may be more cost
effective
to recharge the system every two or three years. Freon recharging is not a
do-it-yourself
job. As per federal law (EPA), only people certified to handle refrigerant (freon) are allowed to
recharge
an air conditioning system.
Outside Unit Is Dirty Or Air Around Outside Unit Is Blocked:
Visually check the coil of the outside unit to make sure that
it is not
excessively dirty or blocked. If the coil is dirty you can flush it with a garden hose. Keep
water clear
of electricals.
Compressor burnt out or locked, or not running for some other
reason:
If the fan on the outside unit is running but you do not hear
the sound of
the compressor running, then the compressor is malfunctioning. This would be a very
serious
problem requiring an a/c contractor.
Air Return is sucking in hot air:
If you have an air return duct in a hot area such as an attic
or garage,
make sure that this duct is not broken, split, or disconnected and sucking in hot air. 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
your air
conditioner because the important parts, like the blower assembly, the cooling
coil, and other inner parts will stay cleaner, operate more
efficiently and
last longer.
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.
etc.
