My A/C is running outside but its blowing out warm air its not cooling. what is the problem

The relay switch is bad. Needs changed.

What is a relay switch

Are you sure the compressor is running outside? The fan can run but the compressor might not be running. That you need to check first.

I don't know if the compressor is running are not

If you do not know at least that much I can be of no help.

Only thing i know is my outside unit the fan is on and its blowing out cold air compare to everybody else unity thats A/C is WORKING!! there is blowing out hot air.. so i don't know what that mean

It means your A/C is broken and you need to call for professional service. If the fuses were bad it would not be running and for a person such as yourself there are no user serviceable parts inside the unit. Call for professional service to get it repaired.

well like a week ago.. the unit wasn't running at all. and the guy from sears was like go and check the breaker box and I did and it was off so i switch it back on and it started working again and then like when it cooled the house off and it turned it self off when it came back on again thats when it started blowing out the hot air

also thanks so much i really appreciate your help
