First, check your thermostat settings and make sure the system is set to “cool” with the temperature below the current room temperature. Then check your circuit breaker to see if it has tripped—this is more common than you might think, especially during peak summer usage.
Look at your air filter and replace it if it’s dirty or clogged, as restricted airflow can cause systems to shut down as a safety measure. Also check that your outdoor unit has power and isn’t blocked by debris, plants, or other obstructions.
If these basic steps don’t solve the problem, call us for professional diagnosis. Many issues require specialized tools and expertise to fix safely, and attempting complex repairs yourself can cause more expensive damage.
