User Error

When your air conditioner is on, make sure that all of the windows and outside doors in your house are closed. It’s also your responsibility to make sure that your air conditioning unit is properly maintained. That means keeping the air conditioning filters and coils clean to avoid premature compressor or fan failure. Finally, thoroughly read through user manual for some basic operating rules that can increase the lifetime of your air conditioning unit and prevent future problems from occurring.

Refrigerant Leaks

If your unit is low on refrigerant, it is likely that you have a refrigerant leak. Refilling your unit’s refrigerant won’t solve this problem. You’ll need to call a professional technician to repair the leak and refill the repaired system with refrigerant. That’s because it’s important that the refrigerant charge precisely matches the manufacturer’s recommendations. If it is undercharged or overcharged, your air conditioning unit won’t work as it should.

Thermostat Sensor Issues

If your unit is behaving strangely by turning on and off at random periods, cycling constantly, or varying heating and cooling options, it’s likely that there is a problem with your thermostat sensor. The thermostat sensor is located behind the control panel and works to calculate the room’s air temperature. It can become dislodged, resulting in faulty temperature measurements. Check and make sure that the sensor is in place behind—but not touching—the evaporative coil. You can adjust the position of the sensor by moving the wire that holds it in place.
