Why Is My AC Running But Not Cooling Properly?
Your AC is likely running but not cooling due to airflow or maintenance issues. Common causes include a dirty filter, dirty outdoor coils, thermostat problems, low refrigerant, a frozen coil, or duct leaks. We inspect filters, ductwork, thermostat calibration, electrical connections, condensate drains, and refrigerant pressure during service. Technicians provide fast diagnostics with 24/7 live answering in Buffalo and Cheektowaga.
Quick checks:
- Set thermostat to Cool, 3°F lower than room temp.
- Replace or clean the air filter.
- Clear 2–3 ft around the outdoor unit.
- Open vents; if you see ice, turn AC off and fan on.
