Mini Split Installation in Raton

Sizing a mini-split here starts with one question: how much heating capacity does this house need, because the compressor will never be called on to cool it. Homes in Colfax County, NM have essentially no cooling season — no month of the year is warm enough to call for it. That means the refrigerant circuit, the coil, and the outdoor unit spend the warmer months standing off rather than cycling, and an idle system can develop faults that only surface when heating demand returns in the fall. A contractor doing a load calculation in Colfax County is solving a heating-only problem, and the equipment they specify has to cover it without the breathing room that a shoulder cooling season would otherwise provide.

Electrical panels in houses this old were sized for demands that look nothing like a modern mini-split. Half the homes in Colfax County, New Mexico were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here checks the service panel early, because undersized service is common enough in stock of this vintage that finding it is ordinary rather than exceptional. What that check turns up decides whether the job is a straightforward mount-and-connect or whether the electrical work becomes its own line item.
