Why Is My AC Running But Not Cooling Properly?
Your AC can run but not cool due to a clogged air filter, dirty outdoor coils, incorrect thermostat settings, or a refrigerant leak. Low refrigerant usually means a leak that should be repaired, not refilled. Blocked drains, failing blower parts, or loose electrical connections can also reduce cooling. Our technicians check filters, coils, refrigerant charge, safeties, blower assembly, and condensate drains during service. We offer 24/7 emergency HVAC service across Madison and nearby cities.
Quick checks:
- Replace the air filter every 1–3 months.
- Clear debris and gently rinse outdoor coils.
- Confirm thermostat is set to Cool and the temperature is lower than room temp.
