A contractor diagnosing a heat pump in Sac County has to decide whether the weather this equipment has run against explains the failure, or whether something else does. 78 severe weather events were recorded in Sac County, Iowa between 2015 and 2024. At that rate, severe weather is an occasional event in this area, not a standing condition, and a compressor or reversing valve that has given out has almost certainly done so from age or from deferred servicing rather than from accumulated storm load. That distinction changes what a contractor prices and what they recommend replacing.

Ductwork in a house built before mid-century was sized and routed for whatever came first, not for a heat pump. By the time a contractor opens the equipment on a repair call, the ducts have been carrying conditioned air through multiple ownership cycles, multiple system swaps, and whatever sealing or patching each one left behind. Half the homes in Sac County, Iowa were built in 1957 or earlier (2020-2024 ACS 5-year). That history shows up inside the duct runs as accumulated debris, deteriorated joints, and airflow paths that no longer match what the heat pump needs to move heat efficiently through the house. A repair that starts with the unit can end with the contractor tracing a fault back to a branch line that has been leaking for years.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit is usually where a contractor starts. It sits outside the house and holds the compressor, which pressurizes refrigerant, and the coil, which exchanges heat with the outdoor air. When that unit is the problem, symptoms show up as warm air inside, ice on the coil, or a system that runs but does nothing.
Inside, the air handler sits in a utility closet, basement, or attic and pushes conditioned air through the house. It holds an indoor coil and a blower motor, both of which a contractor examines when the outdoor unit checks out fine. The refrigerant lines connect the two units, and the reversing valve inside the outdoor cabinet is what lets the system heat and cool.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house and equipment.
