The answer to 'my AC repair won't turn on' is that there can be several common causes, including a tripped circuit breaker, a faulty thermostat, or issues with the compressor or other components. Symptoms may include the unit not powering on at all, the fan not running, or the compressor not kicking in.
In many cases, simple troubleshooting steps like checking the circuit breaker, replacing the air filter, or adjusting the thermostat settings can resolve the issue. However, if the problem persists or you're not comfortable diagnosing the issue, it's best to call a professional HVAC technician to inspect the system and make any necessary repairs.
