The answer to 'my AC repair keeps shutting off' is that there are several common causes, including a clogged air filter, low refrigerant levels, a malfunctioning compressor, or an issue with the thermostat. If your AC unit keeps shutting off, it could be a sign of a larger problem that requires professional diagnosis and repair.
Some common symptoms of an AC unit shutting off include the unit not turning on at all, the unit cycling on and off frequently, or the unit blowing warm air instead of cool air. If you notice any of these issues, it's best to call an HVAC technician to inspect the system and identify the root cause.
