Takes about a minute. No obligation.
A heat pump in this county has been running against serious weather for years, and that history shows up inside the equipment. 267 severe weather events were recorded in Montgomery County, Ohio between 2015 and 2024. At that rate, wear on compressors, reversing valves, and electrical components is not incidental. A contractor here checks what the system has actually been carrying before settling on a cause, because a part that failed under sustained load needs a different repair scope than one that failed from a manufacturing defect or a skipped service.
Half the homes in Montgomery County, Ohio were built in 1966 or earlier (2020-2024 ACS 5-year). A heat pump sitting in a house that old has almost certainly been replaced at least once since the house was built, but the repair job still turns on what the opened system actually contains: whether the compressor, reversing valve, or control board takes a part that is still manufactured, or one that a contractor has to hunt down or substitute. That supply question is what separates a repair that closes in a day from one that stretches while a part gets sourced.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil, which are the pieces under the most mechanical stress. When a heat pump stops moving heat in either direction, a contractor starts here. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in this cabinet are among the first things they rule out.
Inside the house, the air handler hangs in a utility space or closet and pushes conditioned air across the coil and into the ducts. The refrigerant lines that connect the two units, the reversing valve that switches the system between heating and cooling, and the thermostat that tells the whole system what to do are all points a contractor examines when the outdoor unit checks out but the problem persists.
The drawing shows a general layout of a heat pump system, and a licensed contractor determines which components apply and what each needs in your specific home.
