Takes about a minute. No obligation.
A contractor pricing a heat pump repair in Fairfax city has to decide what actually wore the system down. 23 severe weather events were recorded in Fairfax city, Virginia between 2015 and 2024. At that rate, severe weather is an event, not a constant pressure on equipment. A compressor that has given out, a reversing valve that has failed, a refrigerant circuit that is losing charge: those failures point toward installation quality and service history first. The weather here has not been working the system hard enough to carry the blame.
Ductwork in a house this old has absorbed whatever was repaired, retrofitted, and swapped out before the current system arrived. Half the homes in Fairfax city, Virginia were built in 1967 or earlier (2020-2024 ACS 5-year). When a heat pump in stock this old fails, the contractor opens the unit and finds out which generation of components it actually runs on, then checks whether those parts are still manufactured at all. A refrigerant fitting or a reversing valve for a system at the older end of what is running here can be a sourcing problem before it is a labor problem.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually where a repair starts. It houses the compressor, which is the heart of the system, along with the condenser coil and a fan. When the system fails to heat or cool, or makes noise it did not make before, the compressor and coil are among the first things a contractor opens the cabinet to inspect.
Inside the house, the air handler holds the evaporator coil and the blower fan that moves conditioned air through the home. The refrigerant lines connecting the two units and the reversing valve, which is what allows a heat pump to switch between heating and cooling, are also points a contractor checks when the system runs but performs poorly or gets stuck in one mode.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to your specific system and situation.
