First check to see if your outside unit is working and you can here the compressor running. If the fan runs and the compressor does not you have a problem with the capacitor or wires burnt off terminals. If your not sure you know how to work on this please call a service tech ask for free estimate. If the unit compressor and fan runs you may be out of gas that meanns you have a leak. Either way you need a service tech. You can only go so far without the correct tools to work with. Russ

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

My central air unit comes on but it's not cool and


to me it sounds like filter are dirty, need to be cleaned or replaced, home systems, packaged or otherwise are hermetically sealed and should not need freon recharge. Always start with airflow and/or unit being set too low. An AC unit of any type will build ice if a) the filter is plugged up and can't move enough air, b) it has been run without the filter, clogging the coil, again, not moving enough air, c) setting an AC unit below 68 degrees F will almost ALWAYS cause icing, and d) running a standard AC when it's warm inside and cold outside (unless equipped for "low-ambient operation"). When in doubt, a bit of maintenance(thorough cleaning) by someone with AC skills can cure a b, common sense will cure c d.

Central air conditioning system is blowing warm air.


many, many. Is the outside unit running? If it is, is the compressor running? Feel the refrigerant lines leaving the unit. Little one should be warm. Big one should be cold, probably sweating.

central air or window unit? central systems use a low/high pressure limit switches which self reset when pressures are nominal. suction about 50-60, high pressures around 300.

Central air system blows cool air not cold and


your indoor unit is only circulating the air in the house. for your condensing unit. check your breaker in the electric panel. your contactor or your capacitor.
