We service both air-source and ductless heat pump systems.
Auxiliary heat strip issues are checked alongside the heat pump itself.
A heat pump that seems to be 'not heating' is often actually a reversing valve or defrost cycle problem, which a technician trained mainly on standard ac systems can easily misdiagnose, which is exactly why heat pump repair calls in Cornish, ME get treated with urgency, not a next-available-Tuesday slot.

No-heat calls in winter get the same priority as no-cool calls in summer.
You get a quoted price after the reversing valve and defrost cycle are actually tested, not billed for trial-and-error.
Refrigerant charge is verified against heat pump-specific specs, which differ from standard AC charging.
Every job starts with a real diagnosis, not a guess — here's the full scope of what our heat pump repair technicians handle across Cornish, ME.
