A heat pump that stops heating or cooling in Montgomery County is far more likely to have worn out than to have been overwhelmed by outside conditions. 63 severe weather events were recorded in Montgomery County, Indiana between 2015 and 2024. At that rate, severe weather here is an event rather than a constant, and a contractor working a repair does not open the system expecting storm-driven fatigue to be the culprit. What they check first is the compressor's condition, refrigerant charge, and whether the unit was sized and installed correctly from the start. Maintenance history usually tells the story before anything else does.
Parts availability is what decides how a heat pump repair goes in stock this old. Half the homes in Montgomery County, Indiana were built in 1967 or earlier (2020-2024 ACS 5-year). A system installed into a house that spent generations on different equipment has already been through at least one replacement cycle, and the heat pump a contractor opens today may be old enough that the components it needs are out of current production. When a compressor or reversing valve fails and the part is discontinued, the contractor has to find aftermarket supply or price a full replacement, and that search is what determines the scope of the job.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is the piece most homeowners recognize first. It holds the compressor, which is the heart of the system, along with the outdoor coil and a fan that moves air across it. When a heat pump stops heating or cooling, the compressor and that coil are among the first places a contractor looks.
Inside the house, the air handler contains the indoor coil and a blower fan that pushes conditioned air through your home. A reversing valve, which sits in the refrigerant line between the two units, is what allows the system to run in both directions. Problems with either the air handler components or the reversing valve tend to show up as the system running but not doing its job.
The drawing shows a typical heat pump layout, and a licensed contractor will determine which components apply to your specific system and situation.

Heat pumps work against whatever the local climate delivers, and that workload compounds over time with every weather event that forces the system to run harder or recover from a power disruption. How often that happens in Montgomery County shapes how much wear a unit accumulates and how often a contractor gets called out to address it.
