Takes about a minute. No obligation.
A heat pump in Mineral County cycles through heating every single month, which means the refrigerant circuit, the reversing valve, and the defrost board never get the long idle that lets minor faults stay hidden. Homes in Mineral County, CO run heat in every month of the year. The defrost controls in particular take repeated thermal stress each winter cycle, and a contractor will test that board and the associated sensors early in any diagnosis, because failures there account for a wide share of cold-weather calls. Refrigerant charge also drifts under sustained load, so a pressure check is standard before any other repair scope gets set.
Half the homes in Mineral County, Colorado were built in 1985 or earlier (2020-2024 ACS 5-year). A heat pump running in a house built around that period has had time to develop the kind of compressor wear and refrigerant line fatigue that looks like one problem until a contractor opens the unit and finds another behind it. Duct seals that were adequate when the system was first fitted are often the reason a unit has been working harder than it should, and that extra load shows up inside the equipment. The repair scope in stock like this is set by what the opened system actually contains, not by what the symptom suggested from the outside.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and the outdoor coil. The compressor is the first place a contractor looks when a heat pump stops moving heat properly. A failed capacitor, a refrigerant leak at the coil, or a compressor that has seized will all show up here.
Inside the house, the air handler mounts in a closet, attic, or utility room and pushes conditioned air through the vents. The expansion valve and the reversing valve both sit within the refrigerant circuit and are common sources of trouble when the system heats in one direction but not the other. The thermostat, though small, drives the whole sequence and is often the first thing a contractor tests.
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.

Mineral County's weather puts real strain on heat pump systems, which have to work harder and cycle more often when conditions turn extreme. How much stress a unit has absorbed over its life is a local question, and the record below gives that context.
