A contractor diagnosing a heat pump repair in Kent County starts with the components that carry the heating load: the reversing valve, the compressor, and the defrost board. Homes in Kent County, MD run heat about seven months a year, from October through April. Defrost cycles run repeatedly through those months, and the reversing valve switches direction every time the system moves between heating and cooling. That cycling leaves wear the contractor can measure. A compressor that was marginal going into October often fails before April ends.
Heat pump systems in houses this old have frequently been swapped in and out more than once, and what a technician finds once the cabinet is open reflects that layered history. Half the homes in Kent County, Maryland were built in 1978 or earlier (2020-2024 ACS 5-year). A refrigerant circuit or control board from a system installed into a house of that vintage may run on components whose replacement stock is limited or sourced through specialty suppliers rather than standard distributors. That is the variable that decides whether a repair is a same-week fix or a longer job.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually where a contractor starts. It houses the compressor, which is the heart of the system, along with the outdoor coil and a fan that moves air across it. When the compressor is struggling or the coil is damaged, the system loses the ability to move heat in either direction.
Inside the house, the air handler holds the indoor coil and the blower that pushes conditioned air into the home. The reversing valve, which tells the system whether to heat or cool, sits in the outdoor unit and is a common focus when the system runs but delivers the wrong temperature. The refrigerant lines connecting both units carry the working fluid and can develop leaks at fittings or along the line set.
The drawing shows a typical layout, and a licensed contractor determines which components and conditions apply to your specific home.
