Heat Pump Repair & Service in Bethesda, MD
Heat pumps in Bethesda carry the house through humid summers and cold winters, so by year ten they've done a lot of work. When one starts to struggle, it usually shows up as uneven comfort and a bigger electric bill. 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 heat pump repair & service call before they arrive, including which parts and tools to bring.

What a visit includes
Heat pump problems can start outdoors or at the air handler, so we diagnose both and confirm heating and cooling before we leave.
Frequently asked
Why is my heat pump running all the time in winter?
Some long run time is normal on cold days. Constant running with backup heat on means something needs attention.
Is a frozen heat pump an emergency?
Not usually, but it means the system is losing efficiency fast. Call us so it doesn't get worse.
Do you come to Bethesda at night?
Yes. Bethesda is about 5.2 miles from our North Bethesda base, and we take calls around the clock for the 20814, 20816 and 20817 ZIP codes.
About cost
