A contractor called out to repair a heat pump in Crawford County is not walking into a storm-battered system by default. 82 severe weather events were recorded in Crawford County, Iowa between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a grinding background load on the equipment. A compressor that has given out, a reversing valve that has failed, a refrigerant circuit that has lost pressure: those failures trace back to installation quality, run hours and how consistently the system was serviced, not to what the sky has thrown at it.

Ductwork and wiring in a house this old have usually been touched more than once, each time to fit whatever system was going in at that moment, and the repair work reflects that layered history. Half the homes in Crawford County, Iowa were built in 1968 or earlier (2020-2024 ACS 5-year). A heat pump sitting in stock of that vintage is rarely original to the house, which means a contractor opening the unit is looking at equipment that was matched to an existing infrastructure, not built alongside it. What that opens up is a parts question: control boards, reversing valves, and refrigerant fittings from older heat pump generations are not always in current production, and what a contractor finds inside the cabinet decides whether the repair is a straightforward swap or a sourcing problem.

The Parts of a Heat Pump a Contractor Checks First

The outdoor unit is usually where a repair starts. It holds the compressor, which moves refrigerant through the system, and the condenser coil, which releases or absorbs heat depending on the season. When either of those components fails, the whole system stops doing its job.

Inside the house, the air handler contains the evaporator coil and the blower that pushes conditioned air through your home. The reversing valve, which switches the system between heating and cooling mode, sits in the refrigerant line and is a common point of failure when the system runs but delivers the wrong kind of air. The expansion valve and refrigerant lines connecting both units are also part of what a contractor examines.

The drawing shows the general layout of a heat pump system, and a licensed contractor determines what applies to your specific house and equipment.
