Furnace Repair in Bethesda, MD
A cold night in Bethesda is the worst time to discover the furnace won't fire, and it's also when most of them fail. We take heating calls around the clock all winter. 24-7 HVAC of Bethesda serves Bethesda, Edgemoor and Wildwood. Our phones are answered around the clock, every day of the year.
Bethesda housing and systems
Homes in Bethesda are mostly 1930s through 60s brick colonials and Tudors, newer custom homes built on older lots, and condos near downtown Bethesda. Older Bethesda colonials often have the furnace in the basement and a second system in the attic for the upstairs, so we check both whenever one floor is uncomfortable. Knowing the housing in Bethesda helps our technicians plan each furnace repair call before they arrive, including which parts and tools to bring.

What a visit includes
Older furnaces in Bethesda get extra attention on the heat exchanger and flue, since cracks and venting problems are more common as equipment ages.
Frequently asked
My furnace tries three times then stops. Why?
That's a lockout, usually from an ignition or flame sensing problem. It's a safety feature, and it's typically a quick diagnosis.
