Why is my air conditioner not cooling?
An air conditioner may stop cooling because of a dirty filter, a frozen evaporator coil, low refrigerant, a failed capacitor, a thermostat fault, a dirty condenser coil, or a compressor problem.
Call us if the system will not start or will not shut off, if it runs but the air is not cold, if you see water pooling or a refrigerant leak, or if the coils are iced over or filthy.
