Mini Split Installation in Farmington

Sizing a mini-split for San Juan County starts with what the compressor is actually asked to carry each summer. Homes in San Juan County, NM run cooling about three months a year, from June through August. A compressor that runs through a concentrated burst of heat load, then sits dormant the rest of the calendar, does not accumulate wear evenly. Faults that trace back to a poor installation, an undersized unit, or a refrigerant charge set wrong at startup often stay hidden until the first days of June, when the system fires up again and the deficiency shows immediately. A contractor quoting a new install here sets the capacity to cover that concentrated demand, not to average it across the full year.

Service panels in much of this county's housing stock were built for loads that predate the equipment running in them now. Half the homes in San Juan County, New Mexico were built in 1986 or earlier (2020-2024 ACS 5-year). A mini-split draw on a panel from that era often pushes past what the original service was designed to handle, and a contractor has to open the breaker box and read what is actually there before any unit can be matched to the house. The ductwork question does not apply to a ductless system, but the electrical does, and it decides whether the install is straightforward or whether the panel work comes first.
