Heat Pump Repair in Farmington

A heat pump in San Juan County works its reversing valve and refrigerant circuit in two directions across most of the calendar year. Homes in San Juan County, NM run heat about eight months a year, from October through May. Outdoor temperatures fall low enough in winter that the system strains to pull heat from cold air, which loads the compressor differently than summer cooling does. A contractor diagnosing a repair here checks the reversing valve early, because a unit that cycles between heating and cooling modes accumulates stress on that valve faster than one that only cools. Refrigerant charge also shifts under sustained heating load, and a slow leak that goes unnoticed in mild weather shows up plainly once the system has run hard for weeks.

Half the homes in San Juan County, New Mexico were built in 1986 or earlier (2020-2024 ACS 5-year). A heat pump running in a house of that vintage was almost certainly installed long after the house was finished, which means the refrigerant lines, coil condition, and compressor wear tell the story a contractor reads once the unit is open. Parts availability is a real constraint here. If a failed component belongs to a line that manufacturers stopped supporting, the repair either escalates or the equipment gets replaced, and that determination comes from what the opened system actually contains, not from what the house looks like from the street.
