A heat pump that stops working in Blackford County is more likely failing from years of ordinary wear than from anything the weather threw at it. 23 severe weather events were recorded in Blackford County, Indiana between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, and a contractor working a repair here checks refrigerant levels, capacitor health, and contactor wear before the storm record enters the conversation at all. If a compressor has given out, how old it is and how well it was serviced tells you more than the weather log does.
Half the homes in Blackford County, Indiana were built in 1960 or earlier (2020-2024 ACS 5-year). When a heat pump in housing that old is opened for repair, what a contractor finds in the refrigerant circuit and at the electrical connections carries the record of every year that passed between original construction and the equipment that runs in it now. Corrosion at the service valves, weakened wire insulation, and refrigerant lines that have been spliced or left untouched since an earlier system are common findings, and each one changes the scope of the job. Parts availability for the equipment itself is a separate question the contractor resolves once the unit is open and the model is confirmed.
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 repairs start. When it labors, runs short cycles, or goes quiet, the outdoor unit is what a contractor opens first. The indoor air handler hangs in a utility space or closet and moves conditioned air through the home.
The refrigerant lines run between the two units and carry the working fluid that makes the whole system possible. A leak or a blockage in those lines affects everything else. The expansion valve and the reversing valve sit within the system and control how refrigerant flows and in which direction. Either one can cause symptoms that look like a failing compressor until a contractor tests them directly.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and what work is needed in your specific home.
