Homes in San Ramon
San Ramon's older neighborhoods west of I-680 date mostly from the 1970s and 1980s. Dougherty Valley to the east was built mostly in the 2000s and later, with newer two-story homes, townhomes, and HOA-governed communities. Equipment ages vary widely by neighborhood, from original 1980s systems to builder-installed equipment that is now reaching mid-life.

Utilities
PG&E delivers electricity and supplies natural gas. Electricity generation is provided by default through MCE, the community choice program, unless a household has opted out. Your bill will show which applies. This matters when comparing the operating cost of a heat pump against a gas furnace.
Permits
HVAC permits are issued by the City of San Ramon. Many communities, particularly in Dougherty Valley, have HOA rules for exterior equipment.
