My air conditioner is no longer cooling properly. What is the most likely problem?
It could be as simple as replacing a fuse, resetting a circuit breaker or checking to see if the thermostat is set properly. It could be from lack of maintenance such as a very dirty filter. If an electrical problem isn’t the cause, the refrigerant may be low if the system still runs but does not cool properly. This can be corrected by having us add the necessary refrigerant. Most likely, if the problem involves any major part, such as the compressor, you would hear strange noises similar to those of any mechanical equipment not running correctly, or the unit might not run at all.
