Why Is My Air Conditioner Running But Not Cooling Properly?

Your AC can run but not cool due to restricted airflow, low refrigerant, dirty coils, thermostat or electrical issues, or leaky ducts. Common causes in Bloomington and Normal homes include a clogged filter, blocked outdoor unit, or a refrigerant leak. Our technicians perform full diagnostics, check refrigerant, clean coils, calibrate thermostats, and tighten electrical connections. We offer 24/7 emergency service, and stocked trucks mean most repairs finish in one visit.

Quick checks:

• Replace a dirty filter.
• Set thermostat to Cool and lower the setpoint.
• Clear debris 2–3 ft around the outdoor unit.
• Confirm breakers are on and vents are open.
