The answer to 'my air conditioner keeps shutting off' is that there are several common causes, including a dirty air filter, compressor issues, low refrigerant levels, or a problem with the thermostat or electrical system. The air conditioner may be shutting off due to overheating, a tripped circuit breaker, or the unit reaching its set temperature and cycling off.
If your air conditioner is shutting off frequently, it's best to have a professional HVAC technician diagnose and repair the issue. Attempting DIY repairs on an air conditioning system can be dangerous and may void the warranty. A qualified technician will be able to properly inspect the unit, identify the root cause, and make the necessary repairs to get your AC system running reliably again.
