Many homes in Sunnyvale were built during the mid-century expansion of the area and are now reaching the point where HVAC systems need replacement. Most systems last 12–20 years, and many homeowners are upgrading to improve performance, reliability, and overall comfort.
At the same time, solar adoption continues to grow, but many homes still operate on older gas systems that don’t fully take advantage of that energy. Electric systems, such as heat pumps, can align with solar usage and allow homeowners to power both heating and cooling from the energy they generate.
During warmer months, cooling demand increases significantly, often making up a large portion of total HVAC energy use. Proper system selection and design help manage that demand while maintaining consistent comfort.
The right system and design help ensure that energy, comfort, and performance are fully aligned.
