My new A/C keeps freezing up even though there is a clean filter, freon topped off, now what?

Answer by  Bob95 (18)

Is this for a car, or for a house, or for what? If it's a split system, you may have put too much freon in it. If you have put too much freon in it, you may not have enough refrigeration experience to mess with it any further and should call a professional.

Check to see if your AC unit has a drain pipe or hose. Find out where this drain is and if it working correctly. If the drain is clogged, bent, or blocked so that the water can not escape, this will cause the unit to not cool your home and form ice on the outside unit.

A freezing AC is far from uncommon. Even with a full freon level and a clean filter it will freeze for a number of reasons. The compressor runs with the aid of an evaporator fan. Most freezing problems are due to this fan not running when the compressor does. Allow the AC to thaw and check the fan.

Believe it or not, your air conditioning is probably working fine. If you happen to live in an area where there are extremely high levels of humidity during the summer, you will often find that your smaller a/c unit tends to freeze up, many times you can just shut it off and it will work fine again later.

The coils are in both units, Most likely you need the Evaporator coil which should be inside the house, Possibly in the attic or closet or garage.

I have been told that my system freezes up because too much is being required of it. We have a 2. 5 ton, and we need a 3 ton. Also, the seer level is too low. When it freezes, we turn it off for about an hour then turn it back on.
