Takes about a minute. No obligation.
A heat pump repair in Columbia County starts with what the system has been asked to do over its life, and the weather load here sits near the middle of the range nationally. 96 severe weather events were recorded in Columbia County, Pennsylvania between 2015 and 2024. At that rate, severe weather is a real but occasional presence, not something that grinds components down the way a relentlessly active climate does. A compressor or reversing valve that has given out here likely did so because of age, a poor original install, or deferred maintenance. A contractor quoting the repair will check refrigerant charge, electrical connections, and wear on moving parts before weather stress enters the picture at all.
Ductwork and refrigerant lines outlast the part catalogs built around them. Half the homes in Columbia County, Pennsylvania were built in 1970 or earlier (2020-2024 ACS 5-year). A heat pump that has been running in a house of that vintage may need a compressor, a reversing valve, or a control board that the original manufacturer stopped supplying years ago. When a contractor opens the unit, that is the question that decides the repair: whether the part exists and what sourcing it takes. A job that looks routine from the outside can stall entirely on availability.
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 condenser coil. The compressor is where contractors look first when a heat pump stops moving heat altogether. The condenser coil and the fan motor above it are checked when the unit runs but struggles.
Inside the house, the air handler holds the blower motor and the evaporator coil, and it is where refrigerant flow problems show up as ice or warm air at the vents. The reversing valve, which lives in the outdoor unit, is what a contractor checks when the system heats but will not cool, or the other way around. The expansion valve and the refrigerant lines connecting both units are also part of that inspection.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines what applies to the specific setup in your house.

Licensing Rules for Columbia County, Pennsylvania
Pennsylvania names the trade in its own definition: installing central heating or air conditioning is a home improvement under the Act, whether or not the equipment is affixed — so an HVAC installation is work the registration requirement reaches.
A Pennsylvania registration displaces the local one: no political subdivision may require a home improvement contractor to register, license or pay a fee on top of it, though building permits and local code enforcement still apply.
Pennsylvania requires home improvement contractor registration rather than a licence: nobody may hold themselves out as a contractor, or perform any home improvement, without first registering with the Bureau of Consumer Protection.
Severe Weather Events in Columbia County
Heat pumps in Columbia County work against whatever the climate throws at them, and that workload accumulates over time. How hard the equipment runs, and how often it runs at its limits, shapes what repair needs look like here.
