An AC that runs but doesn’t cool usually points to airflow loss, low refrigerant from a leak, dirty coils, or a control issue. The most common cause is a clogged filter or a blocked outdoor unit. Leaks cut heat removal and can freeze the indoor coil, while grime on coils acts like a blanket. Our team serves homes throughout the Bolingbrook area and can pinpoint the cause. For urgent failures, Summers offers 24/7 emergency AC repair.
Check or note these before you call:
- Replace the air filter and clear debris around the outdoor unit.
- Confirm the thermostat is on Cool, Fan Auto, and set below room temp.
- If air is weak or warm, you see ice, or the breaker trips or you smell burning, shut it off and call.
If cooling doesn’t return after those checks, schedule a diagnostic so a licensed technician can test refrigerant, coils, and controls.
