Reliable Heating & Air Conditioning for Sunnyvale Neighborhoods
Sunnyvale is the second largest city in Santa Clara County, combining established post-war suburban tracts with contemporary high-density townhomes and global technology headquarters. PerformanceMech Heating & Air delivers full-service heating, air conditioning, and heat pump solutions engineered specifically for Sunnyvale homes and climate patterns.
Located roughly 20 minutes from our Campbell facility via Highway 85 or Lawrence Expressway, our certified technicians provide dependable repair, maintenance, and system replacement services throughout Cherry Chase, Ortega Park, Heritage District, Fairbrae, Raynor Park, and Lowery. We understand how microclimates—from southern valley heat pockets to northern bay breezes near Moffett Field—impact heating and cooling efficiency across the city.
Modernizing 1960s Cherry Chase & Ortega Park Tract HVAC Systems
A substantial portion of single-family housing in Sunnyvale's Cherry Chase, Ortega Park, and Braly neighborhoods was built between 1954 and 1968. These single-story tract ranch homes were originally constructed with narrow hallway closet furnaces and uninsulated sheet-metal or early flexible ductwork routed through shallow, unconditioned attics.
During South Bay summer heat waves, attic temperatures easily climb above 130°F, causing uninsulated or deteriorating ducts to leak 25% to 35% of their cooling capacity before air ever reaches the living spaces. With the Bay Area Air Quality Management District (BAAQMD) Rule 9-4 phasing out conventional natural gas furnace sales starting in 2029, Sunnyvale homeowners are proactively modernizing. Our installations replace leaky legacy ducts with Title 24 compliant R-8 insulated ducting and install high-SEER2 variable-speed inverter heat pumps that deliver quiet, all-electric comfort while capitalizing on generous Silicon Valley Clean Energy (SVCE) rebates.

Frequently Asked Questions for Sunnyvale Homeowners
If your Sunnyvale home still has original uninsulated sheet-metal ducts or gray flexible ductwork installed over 20 to 25 years ago, they typically leak 25% or more of your conditioned air into the attic. Replacing them with R-8 insulated ducting improves room-to-room temperature balance, reduces electricity bills, and eliminates attic dust and fiberglass particulate infiltration.
