A heat pump failure in Pulaski County sends a contractor looking at refrigerant lines, coil condition, and how old the unit is before they look at weather. 69 severe weather events were recorded in Pulaski County, Illinois between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a standing load that grinds components down season after season. A contactor who finds a failed reversing valve or a compressor drawing too many amps is dealing with something the install or the years put there. The weather is background, not cause.
Ductwork sealed with materials that have since hardened and electrical service sized for older loads are what a contractor opens up to in much of Pulaski County. Half the homes in Pulaski County, Illinois were built in 1969 or earlier (2020-2024 ACS 5-year). A heat pump repair that looks straightforward from the outside can turn into a longer job once a contractor finds a contactor pitted from years of cycling in a house that was never wired with today's demands in mind. The refrigerant circuit may hold, but the supporting components around it carry a different history than the equipment nameplate suggests.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the outdoor coil. The compressor is where most repair calls lead: it pressurizes the refrigerant that the whole system depends on. The outdoor coil transfers heat between the refrigerant and the outside air, and a damaged or dirty coil shows up fast as a system that won't keep up.
Inside, the air handler holds the indoor coil and the blower fan, and it connects the refrigerant circuit to the air moving through your home. The reversing valve sits inside the outdoor unit and is what lets a heat pump both heat and cool. When it sticks or fails, the system runs in one mode only, and a contractor will check it alongside the expansion valve, which controls refrigerant flow between the two coils.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components need attention in your specific home.

Licensing Rules for HVAC Repair in Pulaski 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 Pulaski County
Extreme weather puts heat pumps under load they were not sized to carry indefinitely, and repeated stress shortens the life of components. How hard the weather pushes in Pulaski County shapes how hard the equipment works, which makes repair demand a local fact rather than a general one.
