central air not turning on

HVAC

The answer to 'central air not turning on' is that there can be several common causes, including a tripped circuit breaker, a faulty thermostat, issues with the condenser unit, or problems with the electrical connections. Symptoms may include the air conditioner not powering on at all or the fan not running, and the compressor not kicking in.

Some potential solutions you can try include checking the circuit breaker, replacing the air filter, and ensuring the thermostat is set properly. However, if the issue persists or you're not comfortable troubleshooting the system, it's best to call a professional HVAC technician who can properly diagnose and repair the problem.

    Check the Circuit Breaker

    Locate the circuit breaker for your central air conditioning system and make sure it has not been tripped. If it has, reset the breaker and see if the system turns on.

    Ensure the thermostat is set to 'cool' and that the temperature is set lower than the current room temperature. Check the thermostat's batteries as well.
