This is a guide to help you solve common problems you may have with your air conditioning system.
Please note because of environmental safety there are some things that can only be done by licensed air conditioning professionals, Charging and discharging Freon or Puron is not allowed except by a licensed air conditioning professional, please do not try to do this yourself, it is dangerous to yourself and the environment call a professional air conditioning contractor
5 The unit is iced up and air can not flow through it, the A coil gets a build up of ice be cause of other problems like, a clogged air filter, or low coolant,
3 Reasons that I know of for a unit icing up.
1 Dirty filers, Filters need to be replaced or cleaned every month.
2 the A coil is plugged up because the filter was removed or not installed properly.
The system is low on coolant, you can't do this your self call an air conditioning contractor
Most of the time your A/C will leak because of a clogged condensation drain, The condensation drain (most of the time) is just a 3/4" PVC line, it should have a trap (a "U" shaped fitting) as it comes out of the unit, Sometimes it is as easy as just blowing into the line to clear it, once clear, pour a little bleach down the pipe.
It may also be leaking because the unit is icing up then thawing, See "My Unit Is iced up"
