We completed a comprehensive high-efficiency HVAC installation for this Novato residence, featuring a new Mitsubishi ductless mini-split system. Our team carefully mounted the indoor air handler and the outdoor condenser unit to provide targeted climate control for specific zones in the home. The project involved running new refrigerant line sets with protective covers, installing a dedicated electrical disconnect, and integrating the system with the existing electrical panel. We used digital manifold gauges and precision scales to ensure the refrigerant charge met manufacturer specifications for optimal performance. The final result provides the homeowner with a reliable, energy-efficient cooling and heating solution tailored to their space.
