Sunnyvale's 1960s and 1970s homes often have undersized duct systems — we always check static pressure under the new system and address bottlenecks before they cause comfort complaints.
Sunnyvale's post-war housing stock — many homes built in the 1950s–1970s during Silicon Valley's early growth — presents a predictable HVAC profile: aging ductwork, original furnaces at or past end of life, and homes increasingly retrofitted with AC over the years. We've replaced hundreds of original HVAC systems in Sunnyvale's established neighborhoods.

HVAC FAQ for Sunnyvale Homeowners
Does the City of Sunnyvale require permits for HVAC replacement?
Yes. City of Sunnyvale Building Division requires permits for HVAC equipment replacement.
My Sunnyvale home from the 1960s still has the original furnace — what should I expect?
A 50+ year old furnace has far exceeded its design life. Plan for a full system replacement; we'll test the ducts to see if they need work too.
Are there incentives available for heat pump installation in Sunnyvale?
Incentive programs change in availability and amount. Ask us at the time of your estimate what's currently available — we'll give you an honest, up-to-date answer rather than listing programs that may no longer be accepting applications.
Should I add central AC or a mini split to my Sunnyvale home?
If your home already has ducts in good condition, central AC or a heat pump is typically more cost-effective. Without ducts, a mini split is the right answer.
