A heat pump in Henry County that stops heating or cooling efficiently probably failed for reasons a contractor can measure: refrigerant loss, a worn compressor, or a coil that was never sized right for the house. 50 severe weather events were recorded in Henry County, Indiana between 2015 and 2024. At that rate, severe weather is an occasional pressure on equipment, not the constant load that grinds components down before their time. A contractor working a repair here will check the maintenance history and the original install before treating the weather as an explanation, because in most cases it is not one.

Ductwork in a house this old was put in for equipment that no longer exists, and the heat pump now running in it arrived later, as a retrofit. Half the homes in Henry County, Indiana were built in 1961 or earlier (2020-2024 ACS 5-year). When a repair call comes in, what settles the scope is whether the parts a given system takes are still manufactured. A compressor or reversing valve in a unit installed well after the house was framed can sit in a parts dead zone, common enough that a contractor prices the repair only after confirming availability, not before.
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 drives the whole system, and the outdoor coil, which pulls heat from or releases heat into the air outside. When either one fails, the system stops moving heat into or out of the house.
Inside, the air handler holds the indoor coil and the blower fan, which together condition and circulate air through the home. The reversing valve, refrigerant lines, and expansion valve connect the two units and control how refrigerant flows between them. Any of these can be the source of a problem.
The drawing shows a typical heat pump layout, and a licensed contractor determines which components apply to your specific house.

Weather puts load on heating and cooling equipment, and that load accumulates differently depending on where a system runs. A heat pump working through the conditions Henry County sees is a local question, and the repair needs that follow from it are too.
