A heat pump in Buncombe County has been working against real weather pressure across its life, and that shapes what a contractor looks at first when something fails. 88 severe weather events were recorded in Buncombe County, North Carolina between 2015 and 2024. At that rate, refrigerant lines, capacitors, and the reversing valve all absorb more cumulative stress than the same components in a quieter area, so a repair visit here starts with those before turning to the electrical board or the thermostat. A failure that looks like a simple component swap sometimes opens into a broader inspection once a contractor sees what the system has actually been running against.

Ductwork and wiring that have been in service through multiple equipment cycles carry wear that shows up the moment a contractor opens a heat pump for diagnosis. Half the homes in Buncombe County, North Carolina were built in 1991 or earlier (2020-2024 ACS 5-year). A refrigerant circuit in a house that age has been serviced, patched, and run hard through seasons that push both heating and cooling modes, and what a contractor finds inside the cabinet reflects that history: corroded contacts, stressed capacitors, or a coil that has been losing charge slowly enough that the homeowner did not notice. The parts a system of that vintage requires are not always in local supply, which is what determines whether a repair closes in one visit or stretches into a sourcing problem.
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 the condenser coil. These are the parts a contractor reaches first when a heat pump stops heating or cooling, because the compressor does the core work and the coil transfers heat at the outdoor side. A failed compressor or a damaged coil shows up fast in the diagnosis.
Inside, the air handler hangs in a closet, attic, or utility room and contains the indoor coil, the blower motor, and the expansion valve. The refrigerant lines run between the two units, and the thermostat on the wall tells the whole system when to run. Any of these can be the source of a fault.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house and equipment.
