A contractor diagnosing a heat pump repair in Iowa County has to separate what the climate asked of the equipment from what wore it out. 90 severe weather events were recorded in Iowa County, Wisconsin between 2015 and 2024. At that rate, severe weather is a background condition rather than an exceptional one, meaning the compressor, reversing valve, or refrigerant circuit that has given out almost certainly did so because of age or how the system was installed and maintained. Attributing a failed component to storm load in a county with this kind of record is a reach. The contractor checks wear patterns, refrigerant charge, and electrical connections, and those findings point toward the actual cause.
Heat pump repair in housing this old comes down to two things a contractor finds once the unit is open: the condition of components that have been running through Wisconsin winters for years, and whether replacement parts for that generation of equipment are still manufactured. Half the homes in Iowa County, Wisconsin were built in 1975 or earlier (2020-2024 ACS 5-year). A system installed into a house built well before heat pumps were common may carry control boards or refrigerant components that manufacturers have since discontinued, which changes what a contractor can order and what a repair actually costs. If a part is no longer in production, the scope of the job shifts on the spot.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil. The compressor is where most repair calls start. When it struggles, the system loses the ability to move heat in either direction, and the house stays warm in summer or cold in winter. The condenser coil and the fan that pulls air across it are checked alongside it.
Inside the house, the air handler holds the evaporator coil and the blower fan that pushes conditioned air through your home. The reversing valve sits within the refrigerant circuit and is what lets a heat pump both heat and cool. Refrigerant lines run between the two units, and a contractor checks them for leaks whenever the system is underperforming.
The drawing shows a typical heat pump layout, and a licensed contractor determines which components apply and what work is needed in your specific home.
