Heat Pump Installation in San Luis

Sizing a heat pump for Costilla County means settling a question that does not arise in milder climates: how much the unit's heating capacity falls on the coldest nights, and what fills the gap. Homes in Costilla County, CO run heat about ten months a year, from September through June. Through that stretch, outdoor temperatures at elevation drop low enough that a heat pump's refrigerant cycle loses ground, and backup resistance heat picks up the slack. A contractor has to run a proper load calculation, check the service panel's capacity for that backup draw, and size the primary unit to the actual winter low, not the seasonal average. Get that sequence wrong and the backup element carries most of the heating load, which is what the system was installed to avoid.

Ductwork and electrical service are what decide whether a heat pump installation goes straightforwardly or turns into a longer project. Half the homes in Costilla County, Colorado were built in 1985 or earlier (2020-2024 ACS 5-year). Houses built then were wired around heating and cooling equipment with very different load requirements than a heat pump carries, and service panels from that era routinely fall short of what a new unit needs. A contractor will open the electrical panel early, because what they find there sets the scope of the job more than anything else on the site.
