A contractor called out to repair a heat pump in Des Moines County has to decide, before pricing anything, whether the system's condition reflects what the weather here asks of it or something else entirely. 146 severe weather events were recorded in Des Moines County, Iowa between 2015 and 2024. At roughly that rate, severe weather is a periodic presence in this county rather than a grinding constant, which means the refrigerant lines, the capacitor, and the reversing valve have not been working against the climate the way equipment in harder-hit areas has. When those components fail here, age and the quality of the original installation carry more of the explanation than the weather does, and a contractor who starts from the weather is starting in the wrong place.

Older ductwork seals and wears on its own schedule, and so does the equipment that was retrofitted into it. Half the homes in Des Moines County, Iowa were built in 1959 or earlier (2020-2024 ACS 5-year). A heat pump dropped into a house that age was almost certainly installed well after the original build, which means it has been running in conditions the house was not designed around. When a contractor opens a unit here, what slows the job is parts availability. Refrigerant fittings, control boards, and reversing valve components for systems installed into aging stock often sit at the edge of what distributors still carry. That is the repair variable this housing record produces.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit is the piece most homeowners recognize. It holds the compressor, which is the heart of the system, and the refrigerant coil that sits around it. When a heat pump stops moving heat, the compressor and that outdoor coil are where a contractor looks first.
Inside the house, the air handler contains a second coil and the blower that pushes conditioned air through the home. The refrigerant lines run between the two units, and the reversing valve inside the system is what lets a heat pump heat and cool. A fault in the air handler or a refrigerant line problem shows up differently than a compressor fault, so a contractor reads the symptoms before pulling anything apart.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply and what condition they are in for your specific home.
