The answer to 'my AC keeps shutting off' is that there are several common causes, including a dirty air filter, low refrigerant levels, a faulty thermostat, or issues with the compressor or other components. The AC system may be shutting off due to overheating, a tripped circuit breaker, or the unit reaching its temperature setpoint.
If your AC is shutting off frequently, it's best to have a professional HVAC technician diagnose and repair the issue. They can inspect the system, identify the root cause, and make the necessary repairs to restore proper cooling function. While some basic troubleshooting like checking the air filter can be done DIY, more complex repairs should be handled by a qualified technician to ensure safety and prevent further damage to the system.
