A malfunctioning air conditioner can be caused by a number of factors. Air filters that are unclean or clogged are common causes. In other circumstances, your compressor or refrigerant may be malfunctioning. This might result in your air conditioner not blowing air, not turning on, or just not operating correctly.
Before contacting for an ac repair, consider the following
Check that the AC unit is plugged in. If your air conditioner isn't operating at all, it might be because it isn't receiving electricity. Check the main electrical panel to ensure that your AC unit has a functional power supply.
Examine the thermostat. It may seem obvious, but the thermostat is occasionally the blame for your AC not working. You might only need to replace the batteries! Check if your thermostat is turned on and set to cool.
Examine the outside condenser. If your air conditioner is on but not pumping out enough cold air, it's time to step outside and inspect your condenser. Pollen, weeds, grass, and other organic matter can become filthy and/or clog the condenser. In this scenario, remove anything that is in the path. For optimal ventilation, we recommend a minimum of 3 feet of space.
