Located in a Mixed-Dry climate zone, homes in San Marcos have highly specific thermal demands. Understanding these local environmental factors is critical before investing in new equipment or scheduling repairs.
Experiencing a mix of seasonal extremes means your home requires a perfectly balanced HVAC system capable of both efficient cooling in the summer and reliable heating in the winter. A traditional split system featuring a standard air conditioner paired with a gas furnace is a common and effective setup in San Marcos. However, an increasingly popular option is the dual-fuel system, which uses an electric heat pump during moderate weather and automatically switches to a gas furnace only during the most extreme cold snaps, optimizing both comfort and utility costs.
Consult with a local San Marcos technician to perform a proper Manual J load calculation to ensure your new system is sized perfectly for these exact conditions.
