A heat pump that stops working in Schuyler County is almost certainly not a weather casualty. 49 severe weather events were recorded in Schuyler County, Illinois between 2015 and 2024. At that rate, severe weather is an occasional event for any given address, not a chronic load that grinds components down. A contractor quoting a repair here will look first at how old the system is, how it was originally installed, and what maintenance it has had, because those factors carry far more weight in this county than atmospheric stress does. The refrigerant circuit, the reversing valve, and the electrical connections all wear on their own schedule regardless of what the sky does.

Most of the houses here were fitted for heat pump systems long after the buildings were put up, which means the structure has already absorbed whatever adaptation it needed. Half the homes in Schuyler County, Illinois were built in 1971 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump for repair is working out what the refrigerant circuit, the electrical connections, and the reversing valve actually show, not reasoning backward from the permit date on the house. Worn contacts, refrigerant loss, and failed capacitors follow the service history of the equipment, and that history runs on its own clock.
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 problems start. A failed compressor means the system cannot move heat at all. A damaged or dirty coil makes the unit work harder until something else gives out.
Inside the house, the air handler pushes conditioned air through the home and contains the evaporator coil and the blower motor. The reversing valve, which lives in the outdoor unit, is what lets a heat pump heat in winter and cool in summer. When that valve sticks, the system gets locked into one mode. The expansion valve and refrigerant lines connect the two units, and a leak or restriction anywhere along them shows up as poor performance throughout the whole system.
The drawing shows a general layout of how these pieces relate to one another, and a licensed contractor determines what applies to your specific setup.

Licensing Rules for Schuyler County, Illinois
Illinois leaves HVAC licensing to the municipality: state law lets the corporate authorities of each city or village examine, license and regulate heating, air conditioning and refrigeration contractors, and caps the licence fee they may charge at $50 — so who licenses you depends on the town you work in.
Severe Weather Events in Schuyler County by Year
Extreme weather puts heat pumps under stress they were not sized to absorb every day, and that stress shows up later as repair calls. How often that pressure hits in Schuyler County shapes what local equipment goes through and what contractors here work on.
