About Dunn Loring homes
Homes in Dunn Loring are mostly older ramblers and Cape Cods mixed with newer townhouses and condos around the Mosaic District and the Metro. Older Dunn Loring houses often have ductwork that was sized for a smaller system, while the newer townhouses near the Metro usually run heat pumps with attic air handlers. Those details shape how we approach heat pump repair & service in Dunn Loring: what equipment we expect to find, where it sits and how the ductwork is likely laid out.
Cost and timing
Capacitors, contactors and defrost sensors are common and reasonably priced. Reversing valves and compressors are bigger jobs, and on an older heat pump we'll show you how a repair compares with a high-efficiency replacement.
Questions we hear
Should my heat pump have ice on it?
Light frost that melts during defrost is normal. A thick block of ice that stays is not.
Why is emergency heat on all the time?
Usually because the outdoor unit isn't keeping up. Running on emergency heat costs a lot, so it's worth a quick look.
Do you work throughout Dunn Loring?
Yes, from Merrifield to Pine Ridge and the streets off Gallows Road, Lee Highway and Cedar Lane.
