A contractor diagnosing a heat pump repair in Boone County has to decide what actually drove the failure before they can tell you what the fix costs. 99 severe weather events were recorded in Boone County, Indiana between 2015 and 2024. That puts the county in the middle of the national range, which means severe weather is a real but ordinary part of operating here. When a compressor or reversing valve goes out, the weather alone does not explain it. The contractor will look at how long the system has run, whether refrigerant levels have been maintained, and whether previous repairs were done clean.

A heat pump running in a house this age has likely been through at least one equipment generation already, and the repair question that shapes the job is whether the parts the current system takes are still in production. Half the homes in Boone County, Indiana were built in 1995 or earlier (2020-2024 ACS 5-year). That span is long enough that a contractor opening a unit here has a real chance of finding a system whose manufacturer has discontinued the components it needs, which changes the repair from a parts swap into a sourcing problem or a frank conversation about replacement. The age of the house is background; what the opened system turns out to require is what decides the scope.
The Parts of a Heat Pump a Contractor Checks During Repair

The outdoor unit is usually the first thing a homeowner notices, and it is often where a contractor starts. It holds the compressor, which drives the whole system, and the outdoor coil, which pulls heat from or releases heat into the outside air. When either of those components has a problem, the system stops doing its job.
Inside the house, the air handler moves conditioned air through the home and contains the indoor coil and the blower motor. Connecting the two units is a refrigerant line set that runs between them, along with the reversing valve inside the system that lets a heat pump switch between heating and cooling. The thermostat on the wall tells all of it what to do.
The drawing shows a typical layout, and a licensed contractor determines exactly which components apply to your specific system and home.

Weather puts real load on heat pump equipment. Hard conditions wear on components faster, and what counts as hard varies by where you live, which makes repair needs a local question.
