Why Is My AC Running But Not Cooling Properly?

An AC that runs but isn’t cooling usually points to airflow or refrigerant issues. Likely causes include a clogged filter, dirty evaporator or condenser coils, low refrigerant, a mis-set or faulty thermostat, blocked outdoor airflow, duct leaks, or a clogged condensate drain. We handle refrigerant checks, coil cleaning/repair, drain clearing, duct repair, and thermostat fixes, then test for safe, efficient operation. 24/7 emergency service is available in Noblesville and Carmel.

Quick checks:

• Set thermostat to cool and 3–5°F below room.
• Replace/clean the air filter.
• Clear debris around the outdoor unit.
• Check vents are open and unobstructed.
