A contractor diagnosing a heat pump repair in Shawano County has to decide how much of what they find is weather-load and how much is simply accumulated age. 97 severe weather events were recorded in Shawano County, Wisconsin between 2015 and 2024. At that rate, severe weather is a real presence but not the dominant story for most systems. A compressor that has run hard for years and skipped a filter change or two is likely failing for those reasons, and a contractor will work through refrigerant levels, electrical connections, and wear on the reversing valve before attributing anything to storm history.
Ductwork and wiring in a house this old were put in for something, updated for something else, and asked to run what is there now. Half the homes in Shawano County, Wisconsin were built in 1975 or earlier (2020-2024 ACS 5-year). For a contractor opening a heat pump in stock like this, the first real question is parts availability. A system that has been running long enough to need repair has often been running long enough that its components sit at the edge of what suppliers still stock, and a job priced as a straightforward repair can shift when a needed part has to be sourced on a longer lead or has no current equivalent at all.
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 outdoor coil. The compressor is where most repair calls begin. When it fails, the system runs but moves no heat; when the outdoor coil is damaged or fouled, the same result follows.
Inside the house, the air handler holds the indoor coil and the blower that pushes conditioned air through the home. The expansion valve and the refrigerant lines connecting both units are also points a contractor examines early, since a refrigerant leak or a failed valve affects the whole system regardless of which coil or component shows the symptom first.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home and equipment.

Severe Weather Events in Shawano County, Year by Year
Heat pumps work hardest when the weather outside demands the most from them, and that workload builds up over time. How much stress local weather puts on equipment shapes how often repairs are needed and how soon parts wear out.
