A contractor called out to repair a heat pump in Orange County has to settle one question before pricing any part: what actually drove the failure. 69 severe weather events were recorded in Orange County, Indiana between 2015 and 2024. At roughly that rate, severe weather lands as an occasional event, not a standing condition, which means the compressor or reversing valve a homeowner is staring at almost certainly wore out on its own schedule. A contractor will check refrigerant charge, coil condition, and electrical connections, but the diagnosis in this county tends to trace back to the age of the system or the quality of the original install, not to what last summer threw at it.

Ductwork laid in for one kind of system and later adapted for a heat pump carries the history of both in how it runs, where it leaks, and what it has accumulated at the joints. Half the homes in Orange County, Indiana were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor pulling a heat pump apart here will often find that what needs attention sits outside the unit: seals that were never rated for the load, returns that were sized for something else, passages that have narrowed. The parts the heat pump takes may still be available, but whether those surrounding elements are sound is a separate question, and the repair quote that skips it will miss where the real work is.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit sits outside the house and holds the compressor and the outdoor coil. The compressor is the part contractors reach for first when a heat pump stops moving heat reliably. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet will each kill the system in a different way, and the symptoms often look alike until a contractor measures what is actually happening.
Inside the house, the air handler holds the indoor coil and the blower that pushes conditioned air through the home. The reversing valve, which lives in the outdoor unit, is what lets a heat pump heat and cool, and a stuck valve is a common reason a system runs but produces the wrong temperature. The expansion device and the refrigerant lines connecting the two units round out what a contractor traces when the outdoor unit and air handler both appear to be running but something is still wrong.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what condition they are in for your specific home.

Heat pumps work hardest when outdoor conditions swing hard, and that workload accumulates over time. Repair needs in Orange County are shaped by what the local climate puts the equipment through, which is why the weather record matters here.
