A heat pump running through a Garfield County winter is working at the harder end of its range, pulling heat from cold outdoor air while capacity drops with the temperature. Homes in Garfield County, CO run heat about ten months a year, from September through June. The reversing valve cycles every time the system shifts between heating and defrost mode, and on a unit that has been doing that through long, cold months, a contractor checks that valve and the defrost board before assuming the compressor is the problem. Outdoor coil condition tells a similar story. A repair quote here follows from what those components actually show, not from what the age of the unit suggests.

Half the homes in Garfield County, Colorado were built in 1993 or earlier (2020-2024 ACS 5-year). That puts a lot of ductwork in this county in a condition shaped by equipment that has since been replaced, meaning a technician pulling a heat pump apart to find a failed component is also inheriting whatever the distribution system has accumulated around it: seal deterioration, restricted returns, or branch runs that were balanced for something with a different delivery profile. The repair scope on the unit itself may be straightforward. What the ductwork has become in the years since the house was built is a separate question, and it is one that bears directly on whether the repaired system performs once it is back together.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit is where most repairs begin. It houses the compressor, which is the heart of the system, along with the condenser coil and a fan. When a heat pump stops heating or cooling, a contractor starts here, checking the compressor and coil for faults before moving inward.
Inside the house, the air handler holds the evaporator coil and the blower motor, which pulls air across that coil and pushes it through the home. The refrigerant line set runs between the two units, and the reversing valve inside the outdoor unit is what lets the system switch between heating and cooling. Either component can be the source of a problem.
