A heat pump failing in Wabash County is almost certainly failing for reasons that have nothing to do with severe weather. 75 severe weather events were recorded in Wabash County, Illinois between 2015 and 2024. At that rate, most systems here have run through relatively few hard events across their service life, so compressor wear, refrigerant loss, and contactor failure trace back to installation quality and how consistently the equipment was serviced. A contractor quoting a repair here will look at the unit's maintenance record and its age first. Severe weather is not the story this county's numbers tell.
Ductwork laid down for a furnace-and-window-unit setup, wiring sized for a different load, refrigerant lines that have been spliced and re-run over the years: these are the fixed conditions a contractor opens a wall or an air handler to work around. Half the homes in Wabash County, Illinois were built in 1970 or earlier (2020-2024 ACS 5-year). A heat pump sitting in a house that old has a repair story written in what is still available to fix it. When a capacitor fails or a contactor burns, the contractor's first call is to a parts supplier, and if the system's configuration is old enough, that call does not always resolve the same day. The opened unit tells you what generation of components it runs on, and that is what sets the scope of the repair.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil, which are the pieces that do the heaviest work in any heat pump system. When a heat pump stops heating or cooling properly, these are the first places a contractor looks. A failed compressor or a fouled coil will show up fast.
Inside the house, the air handler moves conditioned air through the home and contains the indoor coil and the blower motor. The refrigerant lines running between the two units and the reversing valve, which is what lets a heat pump serve both heating and cooling, are also parts a contractor will examine when diagnosing a fault.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific system and home.

Licensing and Legal Requirements in Wabash 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 Wabash County by Year
Extreme weather puts heat pumps under load they were not built to sustain indefinitely. Repair demand in Wabash County reflects local conditions, and that makes the weather record a relevant starting point for understanding what the equipment here faces.
