HVAC in Cupertino.

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, premium-brand selections (Daikin Aurora, Mitsubishi Hyper-Heat).

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. Daikin Aurora is our most-installed Cupertino brand because of the up-to-12-year equipment (parts) warranty when registered, with our labor coverage on top (2 years standard, 10 with our maintenance plan). Mitsubishi Hyper-Heat is a close second. Both maintain full rated capacity well below Cupertino’s mild 36°F design heating temperature, so balance-point math is essentially trivial.

ADU and home-office mini-split demand

California’s ADU streamlining laws have made backyard ADUs and converted garages one of the most 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.
