A contractor called out for a heat pump repair in Roanoke has to account for what the equipment has already been running against before they can say what failed. 57 severe weather events were recorded in Roanoke city, Virginia between 2015 and 2024. At that rate, severe weather is a standing part of this system's operating life, and components that absorb the hardest cycling, particularly the compressor and the reversing valve, are the ones a contractor checks first. Age and installation quality still determine whether a part gives out, but the load here is real enough that wear on those components is a credible finding rather than a surprise.
Ductwork that has been patched, re-routed, or relined across successive systems is what a contractor opens to when a heat pump repair calls for more than a straightforward component swap. Half the homes in Roanoke city, Virginia were built in 1958 or earlier (2020-2024 ACS 5-year). That history shows up in the condition of flex joints, in wiring that met the code of a different era, and in refrigerant lines that may have been spliced rather than replaced. None of that stops a repair, but it decides what the contractor prices once the system is open and what else they flag while they are in there.
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 two parts that do the heaviest work in the system. When a heat pump is not heating or cooling properly, the compressor and that coil are where a contractor starts. A failed compressor or a fouled coil will stop the system cold.
Inside the house, the air handler holds the evaporator coil and the blower fan, moving conditioned air through the home. The refrigerant line set runs between the two units, and the reversing valve inside the system is what lets a heat pump switch between heating and cooling modes. A stuck reversing valve is a common reason a heat pump blows the wrong temperature air.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to your specific house and situation.
