Home Air Conditioning Problem can anybody help?

Take out the filter and see if the evaporator coil is frozen up. If it is set the system to fan only. Pulling warm air over the block of ice will help thaw it quicker.

After it is thawed out take out the filter and run the system for a couple hours and see if it ices up again. If it does not replace the filter with a standard fiberglass filter. Many of the high efficiency pleated filters block too much air flow and can cause icing. Also make sure all your vents/dampers are open.

If the evaporator still ices up after taking the filter out you need to hire an HVAC tech to trouble shoot. Something is starving the evaporator whether you are low on refrigerant or have a bad metering device only a competent tech can diagnose.

So many morons out there . Francis G is forgetting that not all systems have one run cap. Many have a seperate one for the compressor. Robert M- basic and to the RIGHT answer. No need to say anything else. Good luck!!!

With the AC running go out to the condenser and look at the copper lines. The big one should be cold if it is not you may need freon. If it is not cold, then it could be a bad cap or compressor any number of things.

Ok Since 3 people did not like my answer then my new answer is It is broken.

I am a retired AC Tech So I guess I would not know what is wrong with it.

You have a problem with your compressor. It could be the Freon or whatever agent is being used, or it could be that the compressor is broken. There are two fans used with a cooling system (usually). One fan, or blower, blows the cool air through the ducts. The fan on the outside unit blows outside air to cool the fins where heat is dumped. The compressor is inside the unit. So, even if you see the fans moving outside it does not mean the unit is working. You will need to call someone to look at the system.

i dont know who is giving all negatives here but they re a bunch of no nothing children.

i am an hvac tech and most answers were correct. its probably your compressor. just might be a wire burnt off of the compressor or it may need a shot of refrigerant. service tech will know when he hooks up his gauges.

i can tell you its not your run copassitor since your fan is running because when your cap does foul, your fan doesnt start either.

Probably needs the freon changed. That's what makes the ac cold.

It's either low on refridgerant, which means you have a leak. Or your filter is blocked, and you need to change it.

clean the filter every 30 days?

It is time to have the unit serviced. The freon level is probably low.
