About Great Falls homes
Homes in Great Falls are mostly large single-family homes on wooded lots, many built from the 1970s through the 2000s. A lot of Great Falls homes have well water, long driveways and big footprints, and many still heat with propane or oil furnaces or heat pumps with backup strips because natural gas doesn't reach every street. Those details shape how we approach heat pump repair & service in Great Falls: 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 Great Falls?
Yes, from Great Falls Village to Seneca and the streets off Georgetown Pike, Walker Road and Route 7.
