A heat pump breaking down in Forest County is unlikely to be a weather story. 58 severe weather events were recorded in Forest County, Wisconsin between 2015 and 2024. At that rate, most systems here have spent their working lives in conditions that do not explain worn compressors or refrigerant loss on their own. A contractor quoting a repair needs to look at the age of the unit, how it was installed, and how consistently it has been serviced, because those are the factors doing the damage in a county where severe weather stays infrequent enough to be an event rather than a routine.
Housing built for one generation of equipment gets handed down through the next, and a heat pump in stock this old has often been swapped in around a shell that predates it by decades. Half the homes in Forest County, Wisconsin were built in 1980 or earlier (2020-2024 ACS 5-year). That gap matters at the repair stage because what a contractor pulls out of an opened unit can be anything from a current-production component to a part that requires searching a specialty supplier. The refrigerant line, the control board, the capacitor: each one has its own history inside that cabinet. A contractor who has not opened the system cannot tell a homeowner what the repair costs or whether the parts are still being made.
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. The compressor is usually the first place a contractor looks when a heat pump stops moving heat altogether. The condenser coil and the fan above it are checked when airflow or heat transfer seems off.
Inside the house, the air handler contains the evaporator coil and the blower. The reversing valve, which switches the system between heating and cooling, lives in the outdoor unit and is a common suspect when the system runs but delivers the wrong temperature. The expansion valve sits between the coils and regulates refrigerant flow through the loop.
The drawing shows a typical layout, and a licensed contractor will determine which components apply to your specific system.
