Heat pump compressors in Ulster County take a hard run on the heating side, cycling through cold that regularly pulls outdoor temperatures down to where capacity starts to drop. Homes in Ulster County, NY run heat about eight months a year, from October through May. A contractor quoting a repair here checks compressor health and refrigerant charge before anything else, because those are the parts that degrade under sustained low-temperature load. Reversing valve wear and defrost board failures also show up with more regularity than they would in a milder climate.
Ductwork put in for a furnace or a boiler was sized, routed, and sealed for a different job. Half the homes in Ulster County, New York were built in 1966 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump for repair in a house like that finds the unit itself is only part of the picture: the passages it depends on may be restricting airflow in ways that shaped how hard the equipment ran and how often it failed. Fixing the component without checking what it was fighting produces a shorter repair.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is where most repair calls start: when it fails, the system stops moving heat entirely. The condenser coil sits around it and is the first place a contractor looks for damage, refrigerant leaks, or blockage that starves the whole unit.
Inside the house, the air handler pulls indoor air across the evaporator coil and pushes conditioned air back into the living space. The expansion valve sits between the two coils and controls refrigerant flow. The reversing valve, also inside the refrigerant circuit, is what lets the system heat in winter and cool in summer, and a stuck or failed reversing valve is a common reason a heat pump blows the wrong temperature.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what work is needed in your specific home.

Heat pumps work against outdoor conditions every time they run, and in Ulster County those conditions can shift hard enough to push equipment to its limits. Repair demand is a local fact shaped by local weather, which is why the storm record here matters to anyone keeping a heat pump running.
