Don't Panic — Try These Steps First

Before you pick up the phone, there are several things you can check yourself when your AC stops working. Start with the thermostat: make sure it's set to "cool," the temperature is set below room temperature, and the batteries aren't dead. Next, check your circuit breaker panel — a tripped breaker is one of the most common reasons an AC suddenly stops. Flip it fully off, then back on. Also check that the indoor and outdoor disconnect switches haven't been accidentally turned off.

The Filter and Airflow Check

A severely clogged air filter can cause your AC to shut down as a safety measure. Pull out your filter and hold it up to a light — if you can't see through it, replace it immediately. While you're at it, make sure all supply and return vents throughout your home are open and unblocked by furniture or curtains. Restricted airflow is a surprisingly common cause of AC shutdowns in Asheville homes.

When to Call a Professional in WNC

If you've checked the thermostat, breaker, filter, and vents and your AC still won't work, it's time to call in a pro. Common professional-level causes include a failed capacitor, a burned-out compressor, a refrigerant leak, or a faulty control board. Quality Comfort provides same-day AC repair across Western North Carolina. Our technicians arrive with common parts on the truck so most fixes are done in one visit.

Avoid Making It Worse

Resist the urge to repeatedly flip the breaker or toggle the thermostat on and off rapidly — this can damage your compressor. If your outdoor unit is running but no cool air is coming inside, don't run the system continuously; turn it off and call for service. Running a system with a refrigerant leak or frozen coil can cause permanent compressor damage that turns a $300 repair into a $3,000 one.
