Hi,I will try and help you,I am Ron.Pull the ac back out,and clean it with a water hose on the inside of the unit,look for blockage on the condenser.Some thing or things could be blocking air from coming threw the condenser coils.You might try using a flash light ,and see if you can see threw the coils pretty good.If you can`t that is your problem.Go to a auto parts and ask for purple power.Read warnings on the purple power label.Put the chemical in a spray bottle full strength.Starting at the top and all the way across,spray a lot of the chemical into and on the coils.Repeat this over and over again for about 10 to 15 minutes. Let it set for about 2 minutes and spray again.Then rinse with water hose(be careful not to bend the coil fins over flat).Use the water hose nozzle in fan like pattern so it won`t bend the fins. Is the evaporator getting cold?(where the filter goes,the radiator looking thing)If the evaporator is not getting cold at all(feel all around the coils,down and up and end to end)If it is geting cool or cold any where on the evaporator,the the freon is low.If it is not cold any where ,it is most likely the compressor gone out.Did you purchase a extended warranty with the ac?If you did you may have caught it in time,the warranty should be at least 5 years parts and labor.If I can help ....roniecon@gmail.com
