What we see in Cupertino homes
Climate. Climate zone 4 with mild marine influence, slightly cooler summers than San Jose (design cooling ~88°F). Heating design 36°F.
Housing stock. Most of Cupertino was built between 1955 and 1985, single-story ranches with full ductwork and gas furnace + AC split systems. Garden Gate, Monta Vista, and Stevens Creek have larger custom builds. Newer infill near Apple Park and Westport tends to be code-built 2010+ townhomes.
Typical systems. Heat pump replacement on end-of-life systems (2000s installs are now hitting 25 years), ductless mini-split for ADUs and home offices, Mitsubishi Electric ductless installations and Daikin Aurora service.
Premium equipment expectations
Cupertino customers research equipment carefully. Most homeowners we visit have already compared Daikin vs Mitsubishi vs Lennox spec sheets before we arrive. Our approach is honest: we walk through capacity, modulation range, warranty terms, and refrigerant type. For new ductless installations, we now use Mitsubishi Electric; we continue to repair and service Daikin Aurora. We compare the selected model’s heating output with the load at Cupertino’s winter design temperature. As a Diamond Contractor, we register eligible M-Series and P-Series systems under the 12-year parts and compressor warranty terms (the HM, WR, HX and WX wall-mounted series top out at 10 years).
ADU and home-office mini-split demand
California’s ADU streamlining laws have made backyard ADUs and converted garages one of the common Cupertino HVAC scenarios. The standard install is a single 12,000 or 18,000 BTU/h ductless mini-split, one outdoor unit, one indoor head, full independent climate control. Our free mini-split calculator sizes per-room and walks through ADU-specific considerations including Title 24 compliance and BAAQMD heat pump electrification trends.
