Why Is My AC Not Cooling? 7 Common Causes

No-cooling calls in Waco often come down to airflow restrictions, low refrigerant, failing capacitors, and thermostat configuration issues. Simple checks can rule out filter and breaker problems before dispatch.

A clogged filter can make an otherwise healthy system look failed, especially during peak heat. Replacing filters regularly improves comfort and compressor lifespan.

Refrigerant loss is usually linked to leaks, not normal use. Systems with repeated low charge need leak diagnosis and repair, not repeated top-offs.

Electrical component failures like contactors and capacitors are common in high-heat cycles. These parts are serviceable, but safe testing is essential.

If indoor coils freeze, shut off cooling and run fan mode to thaw before a technician visit. Running the system while frozen can worsen damage.
