What should I do if my AC is blowing warm air intermittently?

If your AC blows warm air off and on, check basics first, then schedule a diagnostic. Common causes are a dirty air filter, low refrigerant, a mis-set or faulty thermostat, dirty coils, or loose electrical connections. Our technicians can clean coils, check refrigerant and leaks, calibrate thermostats, tighten wiring, clear condensate drains, and replace worn parts. We offer same-day and 24/7 emergency service in areas like Bloomington and Normal, and trucks are stocked so most repairs finish in one visit.

Quick checks:

• Set thermostat to Cool and replace the filter.
• Confirm supply/return vents are open.
