A heat pump repair quote in Green County starts with what the system has actually been through, and the weather here is a real but not dominant factor in that picture. 96 severe weather events were recorded in Green County, Wisconsin between 2015 and 2024. At roughly the midpoint of counties nationally, that load is present and worth accounting for, but a compressor that has given out or a reversing valve that has failed is more likely traced to the age of the unit or how it was installed than to storm wear. A contractor will look at refrigerant charge, electrical connections, and component condition before pointing at the weather record.
Older ductwork and aging electrical service do not announce themselves from the outside, but a contractor opening a heat pump in Green County finds them almost immediately. Half the homes in Green County, Wisconsin were built in 1972 or earlier (2020-2024 ACS 5-year). That depth of age means the system a contractor is repairing has likely outlasted the original installation it was set into, and the seals, connections, and line sets around it belong to a different era of the work. A refrigerant leak or a failed capacitor is the call that brings someone out, but what gets opened alongside the unit often extends the job beyond the part that failed.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is the piece most homeowners recognize, a cabinet sitting on a pad beside the house that holds the compressor and the outdoor coil. The compressor is where most repair calls start. When it fails, the system moves no heat at all. The outdoor coil sits around it and is where heat is exchanged with the outside air.
Inside the house, the air handler holds the indoor coil and the blower fan that pushes conditioned air through the home. The refrigerant lines run between the two units, and the reversing valve inside the system is what lets a heat pump both heat and cool. A fault in the reversing valve usually shows up as the system working in only one mode.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what repair each one needs.

Severe Weather Events in Green County
Weather puts hours on HVAC equipment. Every heating and cooling cycle a heat pump runs in response to outside conditions adds wear, and in Green County that workload is shaped by how often the weather turns hard.
