A contractor quoting a heat pump repair in Franklin County starts by working out what the system has already been asked to carry. 268 severe weather events were recorded in Franklin County, Ohio between 2015 and 2024. At that rate, severe weather is a standing condition here, not a rare interruption, and components like the reversing valve, capacitors, and refrigerant lines accumulate wear against it. A unit showing compressor stress or refrigerant loss may have a straightforward age problem, but the contractor has to establish that before pricing the fix, because the load here gives stress-related failures a real alternative explanation.
Ducting in an older house was sized and routed for equipment that no longer runs in it. Half the homes in Franklin County, Ohio were built in 1979 or earlier (2020-2024 ACS 5-year). That gap matters when a heat pump fails, because a contractor opening the unit is not diagnosing the house, they are diagnosing the refrigerant circuit, the reversing valve, the coil condition, and whether the parts that machine takes are still in production. A house built well before today's heat pump generation does not tell you which of those things failed or what the repair bill looks like. The opened unit does.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil. These are where most faults show up. The compressor pressurizes the refrigerant; when it fails, the system stops moving heat in either direction. The condenser coil surrounds it, and a bent or fouled coil forces the compressor to work harder than it should.
Inside the house, the air handler contains the evaporator coil and the blower motor, which pulls air across the coil and pushes it through the house. The reversing valve, also inside the refrigerant loop, is what lets the system heat in winter and cool in summer. A contractor checks it when the unit runs but delivers the wrong temperature.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what work each one needs.
