Why Is My AC Running But Not Blowing Cold Air?

Your AC can run but not cool due to low refrigerant from a leak, dirty or frozen coils, a failing compressor, restricted airflow from a clogged filter, or a thermostat issue. We repair refrigerant leaks, clean/thaw coils, replace worn parts, and calibrate thermostats. If a fix isn’t worth it, we’ll right‑size an efficient replacement. Same‑day emergency HVAC service is available in Bellingham and Franklin. Every repair or install includes a 2‑year warranty; four years for Priority Plan members.

Quick checks:

• Set thermostat to Cool and lower the set temperature.
• Replace a dirty air filter.
• Look for ice on coils.
