Make certain the compressor is running. If it's not running, have the refrigerant level tested.
Condensor is overloading. Had the same problem last year.
Most of the ones that I have seen have dirty condensor coils. That's the coil you see from the outside. They get dirty on the inside of the air conditioner where the fan blows air through it.
An air conditioner blows out heat
Check to see if your condenser fan is running when a/c compressor kick on.
I don't think it blows warm air... but if your talking about the part thats stays outside it blows warm air thats in your home and the part inside "replaces" the warm air with cool air..
If your air conditioner blows air but it's not cold air then you probably need freon in your air conditioner
a/c blows warm air when idles cold when running
The Air Conditioner is on
Well the main reason why your car blows out cold then hot is because the air conditioner may not be working properly. You should go to the car shop and get it fixed.
the system is probably out of coolant.
number of things. you could have a bad condenser fan motor. bad contactor or a bad run cap for the condenser fan motor.
