A heat pump that has stopped heating or cooling correctly could have failed for several reasons, and figuring out which one is the actual job. 95 severe weather events were recorded in Waushara County, Wisconsin between 2015 and 2024. At that rate, severe weather is a real part of operating life here but not so relentless that it automatically accounts for a broken reversing valve or a compressor that will not start. A contractor working through a heat pump repair in this county checks refrigerant charge, electrical connections, and component wear tied to age and maintenance before the weather record enters the diagnosis.
Heat pump systems in older houses spend their service lives running through wiring routes and connection points that were never designed around them. Half the homes in Waushara County, Wisconsin were built in 1977 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit here, what takes time is tracing what surrounds it: whether the electrical connections feeding the system are still solid, whether the refrigerant lines show the wear that comes from years of thermal cycling in a house where they were retrofitted rather than planned. The parts inside the unit get checked, but the junction between the equipment and the house is where a repair quote can move.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit holds the compressor and the condenser coil, and it sits outside the house on a pad or mounted to an exterior wall. The compressor is where most mechanical failures originate, so a contractor will listen to it and measure its pressures before moving on. The coil wrapped around it transfers heat to or from the outside air, and bent fins or refrigerant loss show up here.
Inside the house, the air handler contains the evaporator coil, the blower motor, and the expansion valve. The blower pushes conditioned air through the home, the evaporator coil does the indoor heat exchange, and the expansion valve controls refrigerant flow between the two units. Refrigerant lines run between the indoor and outdoor sections, and the reversing valve, which lets the system heat as well as cool, sits in the outdoor unit and is a common point of failure when a heat pump blows the wrong temperature air.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply to the specific equipment and conditions in your house.
