Why Is My AC Running But Not Cooling Properly?
Your AC usually runs without cooling because of restricted airflow or low refrigerant. Other common causes include a dirty filter, a frozen evaporator coil, a blocked outdoor condenser, thermostat issues, or duct leaks. Try these quick checks:
- Replace the air filter.
- Set the thermostat to Cool and lower the setpoint.
- Clear debris around the outdoor unit and open supply vents.
- If you see ice on the lines, turn the system off to defrost. We provide 24/7 diagnostics in Bloomington and Normal with upfront pricing and fully stocked trucks.
