An AC running but not cooling usually means a problem with airflow, refrigerant charge, thermostat control, electrical parts, or a blocked drain that’s reducing performance. The most common issue we see is restricted airflow from a dirty filter or coil that prevents heat from leaving the home. A system can hum for hours while a dust-packed coil can’t absorb enough heat to cool. We routinely solve this in homes around Greenfield and nearby communities, and our technicians arrive in fully stocked trucks so most repairs can be completed on the same visit.
Before a technician arrives, check or note these:
- Weak airflow from vents
- Dirty coils or a clogged filter
- Thermostat settings or wiring problems
- Condensate drain line blockage
- Electrical component failure (capacitor, contactor)
- Low refrigerant indicated by poor cooling
If you see water around the air handler or outdoor unit, turn the system off and schedule service promptly.
