Why Is My Air Conditioner Running But Not Cooling Properly?

Your AC can run but not cool due to a clogged air filter, dirty coils, low refrigerant, thermostat problems, or duct leaks. We diagnose the issue, review findings and pricing upfront, and can often start repairs immediately from our well‑stocked trucks. We service central air and ductless mini‑splits, offer same‑day and 24/7 emergency help, and recommend spring tune‑ups to prevent problems in Glendale Heights and nearby.

Quick checks:

• Set thermostat to Cool and lower the setpoint.
• Replace the air filter.
• Clear debris around the outdoor unit; keep fins straight.
