Leaking in of warm air

If the room feels warm, check the window seals surrounding the AC unit to ensure that there is no outflow of cool air or inflow of warm air. If that is the case, use bits of weather stripping to reseal the seals around the AC system.

Flawed wiring

It is risky to have uncertified or haphazard A/C wiring, which can even lead to potential fire hazards. Faulty wiring can cause the circuit breaker to trip or even prevent your AC from drawing power.

Outside fan not working

The outside fan of your AC unit transfers heat from your room to the outside. In case, the fan on your outside unit is not performing well, heat transfer cannot occur properly. The compressor of your AC system can get overheated and the safety overload may even trip. The compressor might also suffer internal damages.

Therefore, it is a good idea to call an AC technician for routine service at least once every year before summer to explore possible issues in your air conditioning unit that might need repair.
