Sunnyvale's housing includes established post-war neighborhoods, iconic Eichler homes with radiant floors and post-and-beam construction, and newer developments near tech campuses. Many homeowners are upgrading to efficient heat pumps that deliver powerful cooling during Sunnyvale's warm summers while operating efficiently year-round. Eichler homes especially benefit from ductless heat pumps that preserve their architectural character while providing modern comfort.
We serve Sunnyvale's tech-focused commercial sector, including corporate campuses in Moffett Park, downtown retail and restaurants, office buildings, medical facilities, and data centers.

Sunnyvale's Silicon Valley location creates warm summer temperatures-routinely reaching 85-95°F from June through September, often hotter than coastal areas. This makes efficient air conditioning essential for comfortable living and productive home offices. We recommend modern variable-speed heat pumps that deliver powerful cooling during warm weather while operating efficiently year-round. These systems also handle Sunnyvale's mild winters perfectly, often eliminating the need for a separate gas furnace and reducing both energy costs and carbon emissions.
