A heat pump running repair work in Belknap County puts strain on parts that have seen little rest. Homes in Belknap County, NH run heat about nine months a year, from September through May. The compressor cycles through heating demand all winter, then turns around and handles cooling before the season fully closes. Reversing valves, refrigerant lines, and the coil all carry that combined load. A contractor diagnosing a fault here checks those components for wear that reflects continuous duty, not occasional use.
Refrigerant lines age, compressor valves wear, and control boards for older heat pump models go out of production. What a contractor finds once the unit is open determines whether the repair is a parts order or a conversation about replacement. Half the homes in Belknap County, New Hampshire were built in 1979 or earlier (2020-2024 ACS 5-year). A system installed into a house of that vintage may itself be a second or third generation of equipment, and the odds of discontinued components rise with each generation. That is the variable a contractor prices first: not the labor, but whether the part the system takes still exists.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize, a cabinet that sits on a pad beside the house, and it holds the compressor and the outdoor coil. The compressor is where contractors look when a system has stopped moving heat altogether. A failed coil, a refrigerant leak at a fitting, or a seized compressor each shows up here first.
Inside the house, the air handler contains the indoor coil and the blower fan that pushes conditioned air through the home. The reversing valve, which lives in the outdoor unit, is what lets the system run in either direction, and a fault there can leave a heat pump stuck in one mode. The refrigerant lines connecting both units and the expansion valve are also on a contractor's checklist when pressures or temperatures read wrong.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to the specific setup in your house.

Licensing Rules for HVAC Repair in Belknap County, New Hampshire
New Hampshire's mechanical licensing board issues nine credentials — hearth system, four fuel gas endorsements, domestic appliance technician, and master, journeyman and apprentice plumber — and a licensee may not work outside the specialty their licence names. None of the nine is an HVAC licence.
New Hampshire does not license HVAC as a trade, and says so where it matters: the plumbing licence expressly does not reach a person installing heating, cooling, air conditioning or domestic water heating systems, whether solar, oil, gas or electric. The gas piping on a gas-fired system is a separate matter and needs a fuel gas fitter licence.
