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
the system is low on freon. The only reason a system would need freon is because the freon leaked
If the leak is not sealed before recharging with freon, the freon will eventually leak out
Leak repairs are expensive so if it's a small leak it may be more cost
to recharge the system every two or three years. Freon recharging is not a
job. As per federal law (EPA), only people certified to handle refrigerant (freon) are allowed to
an air conditioning system.

If you have an air return duct in a hot area such as an attic
make sure that this duct is not broken, split, or disconnected and sucking in hot air.

is the biggest enemy of your air conditioner!

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.
