An AC that runs but isn’t cooling usually means restricted airflow or low refrigerant, not a failed compressor. The most common cause is a dirty filter or a clogged outdoor coil that starves the system of air.
Other frequent reasons include a thermostat set to “On” (fan only), blocked or closed supply/return vents, leaky or crushed ducts, a frozen evaporator from low refrigerant, or a full condensate drain shutting cooling down. Our technicians serve the Wanatah area and inspect the entire system, explain findings, and provide upfront pricing with parts and labor typically covered for one year.
Try these quick checks before calling:
- Replace a dirty air filter and clear 2 feet of debris around the outdoor unit
- Set the thermostat to “Cool” and “Auto,” then lower the setpoint 3–5 degrees
- Open supply/return vents and confirm the breaker isn’t tripped
- If you see ice, shut the AC off and run the fan to thaw
If you suspect a refrigerant leak or hear hissing, schedule professional service promptly.
