On a heat pump repair call in Franklin County, the compressor and reversing valve are where a contractor starts. Homes in Franklin County, NY run heat about nine months a year, from September through May. Heating is the harder duty cycle for a heat pump: capacity drops as outdoor temperatures fall, so the system works harder precisely when conditions are worst. That sustained load wears the compressor and stresses the reversing valve in ways a short season would not produce at the same rate. A refrigerant charge check and a reversing valve test belong at the front of the diagnosis, not after a visual sweep of the easier components.
Ductwork that has been rerouted and electrical that has been patched carry a record of every system that ran in the house before the current one, and a heat pump repair in Franklin County is where that record becomes relevant. Half the homes in Franklin County, New York were built in 1967 or earlier (2020-2024 ACS 5-year). When a refrigerant fault or a failing compressor puts a technician inside the unit, what they find there determines whether parts are still in production for that model. A house whose infrastructure was adapted for successive systems may have also seen successive equipment choices, which means the unit's vintage and the house's vintage can sit far apart. The repair scope follows what the opened system actually contains.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is where most repair calls begin. When it fails, the system stops moving heat altogether. The condenser coil surrounds it, and a bent, dirty, or damaged coil forces the compressor to work harder than it should.
The air handler sits inside, usually in a closet, attic, or utility room, and it pushes conditioned air through the house. Inside it, the evaporator coil and the expansion valve work together to shift the heat. The reversing valve, which tells the system whether to heat or cool, is another piece a contractor checks when the system runs but delivers the wrong result.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply and what condition they are in for this particular house.

Extreme weather puts real stress on heat pump systems, running them harder and longer than ordinary conditions demand. How much of that load a unit has absorbed over its lifetime is a local question, and the answer shapes what a repair technician finds when they open the equipment.
