Installing a mini-split AC in California, especially in the San Francisco area, involves careful consideration of local building codes and permitting processes, which can vary significantly by city. Our installation begins with a thorough assessment of your home's layout, insulation, and window efficiency to determine the optimal placement for indoor and outdoor units. We identify the best locations for air distribution from the indoor unit and efficient operation for the outdoor condenser. A small conduit is drilled through an exterior wall to house the refrigerant lines, power cables, and condensate drain. The indoor unit's wall bracket is securely fastened, followed by mounting the unit itself. The outdoor condenser unit is then positioned on a stable, level surface. Refrigerant lines are carefully run through the conduit, and electrical wiring is managed according to safety standards. The system is then charged with refrigerant, subjected to leak testing, and powered on for a complete performance verification. Installation costs are influenced by the number of zones, the complexity of the installation, and the specific mini-split model.
