Takes about a minute. No obligation.
A contractor quoting heat pump repair in this area spends real time on installation quality and equipment age before drawing any conclusions about weather stress. 47 severe weather events were recorded in Kewaunee County, Wisconsin between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a constant one, which means a refrigerant leak or a failed capacitor has a more plausible explanation sitting right in front of the contractor: how old the unit is and how well it was put in. A rushed install or a system past its service window will break down in quiet weather just as readily, and the repair scope follows from that, not from the storm record.
Refrigerant lines and electrical connections in a house this old tend to carry a record of every technician who worked on the system before this one. Spliced wiring, rerouted line sets, and makeshift fixes accumulate quietly behind panels and in crawl spaces, and they only show up once a contractor opens the unit and traces back what feeds it. Half the homes in Kewaunee County, Wisconsin were built in 1970 or earlier (2020-2024 ACS 5-year). That history shapes what a repair here actually costs, because a contractor who finds a failed reversing valve also has to decide whether the wiring serving it is sound enough to trust.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and one set of coils. When a heat pump stops moving heat properly, the compressor and its associated components are where a contractor starts. A refrigerant leak, a failed capacitor, or a seized compressor each shows up here.
The air handler lives inside, usually in a utility closet, basement, or attic, and it holds the indoor coil and the blower. The reversing valve, which is what lets a heat pump switch between heating and cooling, sits in the refrigerant loop and is a common point of failure when the system runs but delivers the wrong temperature. The thermostat ties the two units together and is checked early because a wiring or calibration fault there can mimic a much larger problem.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and situation.
