Takes about a minute. No obligation.
A heat pump flagged for repair in this county has been working against severe weather that arrives often enough to count as ordinary operating conditions. 405 severe weather events were recorded in Polk County, Iowa between 2015 and 2024. At that rate, wear on components like the reversing valve, capacitors, and compressor reflects sustained stress rather than one unlucky season. A contractor quoting a repair here looks at cumulative load first, because the pattern of what has failed tends to follow it.
A house built when much of Polk County's stock was new has put its heat pump through a long run of Iowa winters and summers, and what a contractor finds inside the opened unit reflects that. Half the homes in Polk County, Iowa were built in 1982 or earlier (2020-2024 ACS 5-year). Contacts corrode, capacitors weaken, and reversing valves stick in ways that only show up once the covers come off. The repair scope is set by those findings, not by what the thermostat display reads or what the homeowner describes from outside.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is usually where a contractor starts. It houses the compressor, which does the heavy mechanical work of the system, and the outdoor coil, which transfers heat with the air around it. A failed compressor or a damaged coil will stop the system from doing its job entirely.
Inside the house, the air handler moves conditioned air through your home and holds the indoor coil and the blower motor. The refrigerant lines connecting the two units, and the reversing valve that lets a heat pump run in both directions, are also points a contractor examines when the system is not behaving as it should.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply to your specific home and situation.
