Heat pump compressors in Orleans County fail at the cold end of winter, not the middle of it, because that is where the refrigerant circuit is working hardest and the system is straining to extract heat from air that barely offers any. Homes in Orleans County, NY run heat about eight months a year, from October through May. A contractor diagnosing a failed or underperforming unit here checks the compressor and its associated valves before anything else, because those are the parts carrying the load when outdoor temperatures drop and the system cannot coast. Refrigerant charge, valve wear, and defrost cycle function all show stress sooner on a unit that is heating rather than coasting through mild air.
Ductwork fitted for older heating systems does not always move air the way a heat pump needs it to move, and in Orleans County that gap between what the house was built with and what runs in it now shows up inside repair jobs. Half the homes in Orleans County, New York were built in 1955 or earlier (2020-2024 ACS 5-year). A contractor who opens a heat pump here finds the unit itself, and also the duct connections feeding it, which may be restricting airflow enough to cause the fault in the first place. Getting the repair right means checking both.
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 what drives the whole system, and when it fails, the unit runs but moves no heat. The outdoor coil pulls heat from the air, and a bent, blocked, or frozen coil is one of the first things a contractor looks at.
Inside the house, the air handler holds the indoor coil and the blower fan, which pulls air across the coil and pushes it through the house. The reversing valve, which lives in the outdoor unit, is what lets the system switch between heating and cooling. A stuck reversing valve often shows up as a system that heats when it should cool, or does nothing at all. The expansion valve, also inside the refrigerant loop, controls flow between the two coils and is another point a contractor checks when pressures read wrong.

Heat pump systems in Orleans County work against the local climate year-round, and what the weather does here is a direct input to how hard the equipment runs and how often it fails. That load is a local fact, which is why the repair picture in this area belongs alongside the weather record.
