A heat pump failure in Ohio County is more likely a story about age, installation quality, or skipped maintenance than about what the weather has put the equipment through. 47 severe weather events were recorded in Ohio County, Indiana between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, and a contractor running a diagnosis can set it aside early. What they look at instead is the refrigerant charge, the condition of the coil, and how long the system has been running without service. Those factors carry more weight in a repair quote here than any weather load the equipment has accumulated.

Stock built when most of these houses were put up has been running heat pump equipment through decades of Ohio winters and summers, and what gets opened on a repair call reflects that. Half the homes in Ohio County, Indiana were built in 1978 or earlier (2020-2024 ACS 5-year). A compressor or reversing valve pulled from a system that old may still be working, but finding a replacement if it is not is a real constraint a contractor prices before committing to a repair path. That search, and what it turns up, shapes whether the job is a straightforward fix or something that changes scope once the unit is open.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit is where most repairs begin. It holds the compressor, which is the heart of the system, along with the condenser coil and a fan that pulls air across it. When a heat pump stops moving heat in either direction, the compressor and that coil are where a contractor looks first.
Inside the house, the air handler contains the evaporator coil and a blower that pushes conditioned air through the home. The refrigerant lines running between the two units, and the reversing valve that switches the system between heating and cooling, are also common points of failure a contractor will inspect.

Weather puts a measurable load on heat pump systems, and that load varies by where you live. How hard the equipment works, and how often it gets stressed, is a local fact.
