A contractor coming out to repair a heat pump in Kane County starts with what the system has already been asked to carry. 298 severe weather events were recorded in Kane County, Illinois between 2015 and 2024. At that rate, severe weather is a standing condition for equipment here, and the compressor, reversing valve, and refrigerant lines absorb that load over years. A failure that looks like a straightforward fix often turns out to involve wear distributed across several components rather than one clean fault. The diagnosis has to account for that cumulative load before a repair scope gets priced.
Half the homes in Kane County, Illinois were built in 1985 or earlier (2020-2024 ACS 5-year). A heat pump sitting in a house that old has been running through Illinois winters and summers long enough that what the refrigerant lines, contactors, and capacitors look like once the unit is opened reflects that accumulated stress directly. Parts fail in patterns specific to how long they have been working, and in this stock that run has been substantial. A contractor pulling the panels is often looking at components that have cycled through more heating seasons than the original installer planned for, which means the repair scope depends on what the opened system actually contains, not on what the model number suggests should still be holding.
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 the outdoor coil. These are the pieces a contractor reaches first when a heat pump stops heating or cooling correctly. A failed compressor, a damaged coil, or a refrigerant leak at that cabinet are the repairs that bring a technician out most often.
Inside the house, the air handler hangs in a utility closet, an attic, or a basement and moves conditioned air through the home. The refrigerant lines connect the two cabinets, and the reversing valve inside the outdoor unit is what lets the system shift between heating and cooling. The thermostat and the electrical controls at both ends round out what a contractor traces when tracking down a fault.
The drawing shows a typical layout, and a licensed contractor determines which components and conditions apply to your specific house.

Licensing and Legal Requirements in Kane 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.
