A contractor quoting heat pump repair in Clay County has to work out what the system has already been through before settling on a cause. 141 severe weather events were recorded in Clay County, Iowa between 2015 and 2024. At that rate, refrigerant lines, capacitors, and contactor points have been running against real stress season after season, and a part that looks undersized or degraded on the bench may have simply carried a heavy load for a long time. A failure that reads as straightforward can turn out to need more attention once the full picture of wear is on the table.
Ductwork in a house this old has a history a contractor reads component by component once the system is open. Half the homes in Clay County, Iowa were built in 1967 or earlier (2020-2024 ACS 5-year). A heat pump running in stock that age has almost certainly been replaced at least once since the original install, and the unit sitting there now may belong to a parts generation that manufacturers have quietly moved past. When a repair calls for a specific reversing valve or control board, that is where the job either closes fast or stalls while the contractor works the supply chain.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is the piece most homeowners recognize first, sitting on a concrete pad beside the house. It holds the compressor and the outdoor coil, and when either one fails the system stops moving heat altogether. The compressor is usually where a contractor looks first, since a fault there affects everything downstream.
Inside the house, the air handler contains the indoor coil and the blower that pushes conditioned air through the home. A reversing valve, which lives in the outdoor unit, is the part that lets the system heat and cool, and a failed valve is a common reason a heat pump blows neither warm nor cool air. The expansion valve and refrigerant lines connecting both units round out what a contractor will work through on a repair call.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system.

Severe Weather Events in Clay County, Year by Year
Weather puts hours on a heat pump. Every cycle the system runs to recover from an extreme outside temperature is a cycle that adds wear, and Clay County's climate dictates how many of those cycles a unit accumulates over its life.
