A contractor quoting a heat pump repair in Iowa County has to decide what actually drove the failure. 90 severe weather events were recorded in Iowa County, Wisconsin between 2015 and 2024. At that rate, severe weather is a real but irregular presence, and most systems here spend the bulk of their lives running against ordinary seasonal load, not storm conditions. A compressor that gives out is more likely worn from years of normal cycling than beaten down by weather events. So a contractor checks refrigerant levels, capacitor condition, and the service record before pointing at anything outside.
Ductwork and wiring in a house get inherited and adapted, not replaced from scratch each time a heat pump does. Half the homes in Iowa County, Wisconsin were built in 1975 or earlier (2020-2024 ACS 5-year). When a contractor opens a system in stock like this, what they find in the unit itself is only part of the picture. Refrigerant circuits corrode, contactors wear, and control boards from older production runs carry part numbers that suppliers no longer stock. The age of the building sets the conditions the equipment has been working against, and a repair quote that prices only the component without accounting for what surrounds it will miss what the job actually requires.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the condenser coil. These are the pieces a contractor goes to first when a heat pump stops moving heat properly. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet are common sources of the problem.
Inside the house, the air handler holds the evaporator coil and the blower that pushes conditioned air through the home. The expansion valve and the reversing valve, which switches the system between heating and cooling, are also points a contractor examines when performance drops or the system behaves differently in one mode than the other.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and what work is needed in your specific house.

Severe Weather Events in Iowa County by Year
Storms, hard freezes, and temperature swings put real stress on heat pump components over time. How much a system has worked against the local climate shapes what repair work it needs and how soon.
