Takes about a minute. No obligation.
Before a contractor can tell you what failed on your heat pump, they have to settle what caused it. 153 severe weather events were recorded in Pottawatomie County, Oklahoma between 2015 and 2024. At that rate of severe weather, cumulative stress on refrigerant lines, electrical components, and the compressor itself is a legitimate factor in any diagnosis, not an afterthought. A part that looks like it simply aged out may have been running hard against conditions that shortened the timeline. The contractor's job is to tell those apart, because one points to a targeted repair and the other points to a pattern that will show up again.
Ductwork in a house is not the only thing that accumulates history. Half the homes in Pottawatomie County, Oklahoma were built in 1980 or earlier (2020-2024 ACS 5-year). A heat pump sitting in a house that old is rarely the original equipment, which means a contractor pulling a failed component is working on a system installed well after the structure was finished, and whether that system's parts are still in production is what decides if the repair closes in one visit or stretches into a parts search. The age on the deed tells a contractor almost nothing about what they will find once the unit is open.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize, a metal cabinet that sits on a pad beside the house and holds the compressor, the fan, and the outdoor coil. The compressor is where contractors look first when a heat pump stops moving heat properly. A failed compressor, a seized fan motor, or a coil blocked by debris each produces its own symptom.
Inside the house, the air handler hangs in a closet, an attic, or a mechanical room and holds the indoor coil and the blower that pushes conditioned air through the home. The refrigerant lines running between the two units and the reversing valve inside the system are also common points of failure when a heat pump is heating in one season and cooling poorly in another.
The drawing shows a typical layout, and a licensed contractor will determine which components apply and what condition they are in for your specific home.
