Takes about a minute. No obligation.
Homes in Genesee County, NY run heat about eight months a year, from October through May. Cold air thins a heat pump's capacity, so the refrigerant circuit and the defrost board work harder the deeper the season goes. By the time a homeowner calls for a repair, those components have already logged a long stretch of hard cycling. A contractor working a heat pump here opens the service panel looking at the defrost controls, the reversing valve, and the refrigerant charge before anything else, because that is where the load lands.
Ductwork that was designed around a different system and has been in service since carries its own set of faults, and those faults produce symptoms a heat pump will flag as equipment problems. Half the homes in Genesee County, New York were built in 1956 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump here often finds that the refrigerant circuit and the electrical components are intact, while the duct runs are the source of uneven temperatures or pressure errors. Sealing, separating, or rebalancing that ductwork is a repair task on its own, separate from whatever brought the technician out.
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 the part a contractor reaches for early: when a heat pump stops heating or cooling, a failed compressor is often where the diagnosis lands. The condenser coil sits around it, and a damaged or dirty coil drives the same symptoms.
Inside the house, the air handler pushes conditioned air through the home and contains the evaporator coil and the blower motor. The refrigerant lines run between the two units, and the reversing valve inside the system is what lets a heat pump switch between heating and cooling. A fault in the reversing valve is a recognizable failure with its own pattern.
The drawing shows a general layout of the system, and a licensed contractor determines which components apply and what condition they are in for your particular house.

Extreme weather puts heat pumps under pressure at exactly the moments they are needed most. How hard local conditions push the equipment shapes how often repair work comes up, and that makes the weather record a real factor in understanding HVAC demand in Genesee County.
