Takes about a minute. No obligation.
A heat pump in Green County that stops heating or cooling correctly is pointing at something internal. 96 severe weather events were recorded in Green County, Wisconsin between 2015 and 2024. That rate puts Green County squarely in the middle of the national distribution, and at that level of exposure, severe weather is an occasional pressure on equipment rather than a punishing constant. Compressor wear, refrigerant charge loss, and failing capacitors in this area trace back to how old the system is and how well it was installed, not to what the sky has been doing. A contractor diagnosing the unit will check those first.
Stock built to run something other than a heat pump still has heat pumps in it today, because equipment changes faster than houses do. Half the homes in Green County, Wisconsin were built in 1972 or earlier (2020-2024 ACS 5-year). When a repair call comes in, what the opened unit contains decides the job: the refrigerant circuit, the reversing valve, the control board. If the parts that particular system takes have aged out of production, the repair either sources from a shrinking secondary market or stops being a repair. That is the variable worth pricing before anything else.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil. The compressor is where most repair calls start. When it fails, the system stops moving heat entirely. The condenser coil wraps around it and can collect debris or develop refrigerant leaks, both of which show up as a loss of heating or cooling output.
Inside the house, the air handler contains the evaporator coil and the blower fan. The evaporator coil can ice over or leak refrigerant, and the blower can fail mechanically or lose power to its motor. The reversing valve, which sits inside the outdoor unit, tells the system which direction to run and is a frequent target when the heat pump heats in one season but not the other.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply and what work is needed in your specific home.
