A contractor called out to repair a heat pump in Stark County has to decide what actually wore the system down. 50 severe weather events were recorded in Stark County, Illinois between 2015 and 2024. At that rate, severe weather is an event in this county, not a condition, and it does not explain most of what goes wrong with a compressor or a reversing valve. A system that has failed here failed because of its age, the quality of its original installation, or gaps in its service history. That is where a contractor looks first, and that is what the repair scope reflects.

Ductwork in a house built for a different era of heating carries a record of everything it has moved since: dust loads, seasonal debris, and the residue of whatever system ran before the heat pump. Half the homes in Stark County, Illinois were built in 1956 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump for repair in stock like this checks the duct connections and coil surfaces alongside the refrigerant circuit, because fouled or leaking ductwork can produce the same symptoms as a failing component. Parts availability is a separate question once the unit is open, and it shapes what a repair actually costs.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit sits outside the house and holds the compressor and condenser coil. These are where most repair work begins. A failed compressor means the system cannot move heat at all. A damaged coil or a refrigerant leak shows up here first, and a contractor will go straight to this unit when the system is not keeping up.
Inside the house, the air handler contains the blower motor and the evaporator coil, which push conditioned air through the home. The reversing valve, usually inside the outdoor unit, is what lets a heat pump shift between heating and cooling. When a home gets heat in one mode but not the other, that valve is what a contractor looks at.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and home.
