What Should I Do If My AC Is Running But Not Cooling?

Start with quick checks: set the thermostat to COOL and lower the setpoint, replace or clean the air filter, open all supply/return vents, and look for moisture/leaks, odd odors, or ice on the unit. If warm air or poor airflow persists, schedule diagnostics. Our licensed, background-checked techs perform a full-system review and can repair or replace necessary parts. Lucky’s Comfort Club offers priority service and a 15-point HVAC safety analysis. We serve homes in Rohnert Park, Petaluma, and across Marin/Sonoma.

Quick checks:

• Thermostat on COOL; set 3–5°F lower
• Replace/clean air filter
• Open blocked vents
• Note moisture/leaks, odd odors, or strange sounds
