Takes about a minute. No obligation.
A heat pump in Franklin County has been running against a genuine weather load, and a contractor diagnosing a repair has to account for that before settling on what failed and why. 121 severe weather events were recorded in Franklin County, Illinois between 2015 and 2024. At that rate, stress on electrical components, refrigerant lines, and outdoor-unit housings accumulates in ways that look like age-related wear but trace back to specific events. A contractor who skips that check quotes the wrong repair.
Housing built for something other than a heat pump creates a specific set of conditions a repair contractor has to account for before the equipment itself can be addressed. Half the homes in Franklin County, Illinois were built in 1963 or earlier (2020-2024 ACS 5-year). That means the refrigerant lines, the ductwork, and the electrical service running to a unit in many of these homes were retrofitted at some point, and a repair job can surface problems in any of those systems rather than in the heat pump alone. When a compressor or reversing valve fails, what a contractor finds around it often shapes the scope as much as the failed part does.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize, sitting on a pad beside the house. Inside it, the compressor and the refrigerant coil do the core work of moving heat, and when the system stops heating or cooling properly, those two components are where a contractor looks first. A failed compressor or a damaged coil will shut down the whole system.
Inside the house, the air handler holds a second coil and a blower fan that pushes conditioned air through the home. The reversing valve, which sits in the outdoor unit, is what lets the system run in both heating and cooling modes, and a fault there can make the system behave as though it is stuck in one direction. The refrigerant lines connecting both units and the thermostat wiring feeding the controls round out what a contractor traces when the problem is not obvious.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and home.

Licensing Rules for HVAC Repair in Franklin 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.
