How do I know if my furnace or AC needs repair?
Call for repair when you notice unusual noises (grinding, banging, squealing), weak airflow, warm air in cooling mode or cool air in heating mode, frequent on-off cycling, unexplained utility bill spikes, moisture or ice on equipment, or burning and musty smells from vents.
Small Symptoms Become Big Failures
Most major breakdowns telegraph themselves weeks in advance as minor symptoms. A failing capacitor stresses the motor it serves; a refrigerant leak slowly cooks the compressor. Addressing symptoms early typically costs a fraction of the failure they lead to — and keeps you off the emergency schedule in peak season.
