A heat pump working a repair call in La Plata County has already been through a long accumulation of heating cycles. Homes in La Plata County, CO run heat about ten months a year, from September through June. The reversing valve, which switches the system between heating and cooling modes, cycles far more here than in shorter seasons, and it is one of the first components a contractor checks when the system is not reaching setpoint. Refrigerant charge and the condition of the coils both shift with heavy heating use. A contractor who skips that inspection on the way to quoting a repair risks replacing the wrong part.
Stock built around a certain era carries the heat pump equipment it was outfitted for, and when a repair opens the system, what a contractor finds inside reflects that. Half the homes in La Plata County, Colorado were built in 1993 or earlier (2020-2024 ACS 5-year). A coil, a capacitor, a reversing valve from that generation of equipment is still repairable, but the replacement parts for it occupy a narrower and narrowing slice of what distributors stock. That is the practical constraint a repair job here runs into: the unit opens, the failed component is identified, and then the sourcing question decides whether the fix is a same-day swap or a longer hunt.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil. These are the parts a contractor goes to first, because the compressor does the hardest mechanical work in the system and the coil is exposed to the elements year-round. When either is the problem, the symptoms tend to be clear: the system runs but moves no heat, or it trips off shortly after starting.
Inside, the air handler houses the evaporator coil and the blower, usually in a utility room, basement, or closet. The refrigerant lines connect the two units, and the reversing valve inside the outdoor cabinet is what lets a heat pump move heat in both directions. A contractor checks the valve, the coil, and the blower when indoor performance drops but the compressor appears to be running.

Extreme weather puts heat pumps under real stress, and equipment that runs hard through harsh conditions wears differently than equipment that does not. How often that stress arrives in La Plata County shapes how much repair work local systems actually see.
