A heat pump asked to carry Cache County winters earns its wear on the refrigerant circuit and the defrost board, not on the compressor alone. Homes in Cache County, UT run heat about ten months a year, from September through June. Through those cold months, the outdoor coil ices regularly, and the defrost cycle fires to clear it, stressing the reversing valve and the defrost controls every time it does. A contractor diagnosing a failed heat pump here checks those components before anything else, because they carry the load of heating a cold climate without the breaks a milder winter would give them.
Ductwork in a house built for an earlier generation of heating equipment was sized and routed around a different system than what a technician is opening today. Half the homes in Cache County, Utah were built in 1992 or earlier (2020-2024 ACS 5-year). That gap between what the house was built for and what runs in it now is where repair work gets complicated: a failed reversing valve or a worn contactor in a heat pump of that era may call for parts that fewer suppliers stock, and a contractor pulling the covers off has to confirm what generation of components is actually inside before a parts order makes sense.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad outside the house and holds the compressor and the condenser coil. These are where a contractor starts when a heat pump stops heating or cooling properly. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet are common findings.
The air handler lives inside, usually in a closet, attic, or utility room, and it contains the indoor coil and the blower that moves conditioned air through the house. The reversing valve, which is what lets the system heat in one season and cool in another, is part of the refrigerant circuit and gets checked when the system runs but delivers the wrong temperature.
The drawing shows a typical layout, and a licensed contractor determines which components apply and need attention in your specific home.

Licensing and Legal Requirements in Cache County, Utah
Utah’s contractor licence does not reach alteration, repair, remodelling or improvement of a building worth less than $7,000 in labour and materials together, counting every change and addition to the agreed work — though the plumbing and electrical trades are pulled back under licensure even below that figure.
Utah requires a state licence before engaging in a licensed construction trade or contracting activity, and HVAC contractor is one of the licence classifications the state issues.
Severe Weather Events in Cache County by Year
Extreme weather puts heat pumps under strain, and how hard the equipment works over time shapes what repairs it eventually needs. Cache County's weather record is part of that picture.
