Takes about a minute. No obligation.
A heat pump in this county has been running against real weather pressure for its entire service life. 147 severe weather events were recorded in Garvin County, Oklahoma between 2015 and 2024. At that rate, the wear a contractor finds on a compressor or reversing valve is load wear, the kind that builds across seasons rather than arriving in a single event. A contractor quoting a repair here checks those components first, because in a place where severe weather is routine, that is where the damage accumulates.
Ductwork in a house this old was sized and routed for whatever came before the current unit, and that history is already baked in by the time a contractor opens the equipment. Half the homes in Garvin County, Oklahoma were built in 1973 or earlier (2020-2024 ACS 5-year). What that means for repair work is specific: a heat pump of the age common in this stock draws on a parts catalog that has thinned considerably, and what a contractor finds inside the cabinet decides whether a fix is straightforward or whether sourcing becomes the longer half of the job. Refrigerant fittings, capacitors, and reversing valves on older units do not always have direct replacements still in production.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize: a metal cabinet sitting on a pad beside the house, holding the compressor and one set of coils. The compressor is the heart of the system, and when a heat pump stops moving heat altogether, that is where a contractor looks first. The coils alongside it are another early stop, since damage or heavy fouling there shows up fast in performance.
Inside the house, the air handler hangs in a closet, attic, or utility room and holds the indoor coil along with the blower that moves air through your living space. The reversing valve lives inside the outdoor unit and is the part that lets the system run in both directions. The expansion valve and refrigerant lines connect the two cabinets and are checked when pressures or temperatures read wrong.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and what work is needed in your specific home.
