A contractor quoting a heat pump repair in Lee County starts with the unit's age and service history, not the weather. 126 severe weather events were recorded in Lee County, Illinois between 2015 and 2024. At that rate, severe weather is an occasional event here rather than a persistent operating condition, which means a failing compressor or refrigerant problem is almost always a maintenance or age story. Components wear on their own schedule, and a contractor who attributes a failure to storm load in this county is reaching past what the record supports.
Much of the housing here carried other heating systems long before heat pumps were part of the picture, and the ductwork and electrical work in those houses reflects that history. Half the homes in Lee County, Illinois were built in 1960 or earlier (2020-2024 ACS 5-year). When a heat pump in stock like this needs repair, the opened system can surface conditions specific to those earlier adaptations: duct joints sealed by previous contractors, wiring run for different loads, connections that have been revisited more than once. Parts availability for the equipment itself is what a contractor prices against; what surrounds the equipment is what can change the scope of the work.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize: a metal cabinet sitting on a pad beside the house that holds the compressor and the outdoor coil. The compressor is where a contractor looks early, because when it fails the system stops moving heat entirely. The outdoor coil sits around it, and a damaged or dirty coil shows up as poor performance in any season.
Inside the house, the air handler holds the indoor coil and the blower fan, usually in a closet, utility room, or attic. The blower pushes conditioned air into the living space, and the reversing valve, tucked inside the system, is what lets a heat pump heat in winter and cool in summer. A fault in the reversing valve is a common reason a system blows the wrong temperature air.
The drawing shows a typical layout, and a licensed contractor determines which components are involved in the specific problem at your house.

Licensing Rules for HVAC Repair in Lee 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.
