The answer to 'my central air keeps shutting off' is that there are several common causes, including a dirty air filter, a problem with the thermostat, issues with the compressor, or a refrigerant leak. When the air conditioning system keeps shutting off, it's usually a sign of an underlying issue that needs to be addressed.
Some common symptoms include the air conditioner cycling on and off frequently, the home not cooling properly, or the system shutting off after running for a short period. Possible solutions can include replacing the air filter, adjusting the thermostat settings, or having a professional HVAC technician inspect and repair any issues with the compressor or refrigerant system.
