McGary's Gas Heating Service | HVAC Services in Bellingham, WA 98229

Yes, that's a classic sign of an air handler fan failure, a common issue we see in Bellingham. The blower motor may have failed, a capacitor might be bad, or there could be an electrical issue. Our technicians will diagnose the exact cause and perform the necessary repair to get warm air flowing through your vents again quickly and safely.

This is often caused by leaks or disconnections in your ductwork, which allow heated air to escape into your attic or crawlspace before it reaches the room. We perform thorough duct inspections to locate these leaks, which are common in older homes, and seal them with professional-grade materials. This improves comfort, balances temperatures, and can lower your heating bills.

Our preventative maintenance includes cleaning critical components, checking for carbon monoxide leaks, testing safety controls, lubricating moving parts, and inspecting the heat exchanger and duct connections. This proactive service is crucial here because it catches small issues—like a weakening fan motor or a minor duct leak—before they turn into costly, no-heat emergencies during our coldest, wettest weather.
