Heating and air conditioning in Oakland

Homes in Oakland

A large share of Oakland homes were built before 1940: Craftsman bungalows, Victorians, and early-1900s homes in the flatlands, with later hillside homes above. Older homes frequently have floor furnaces, wall furnaces, or converted gravity furnaces, and many have no AC. Basements and crawlspaces are common, while usable attics are not always available. Duplexes and small multi-unit buildings often have a separate heater for each unit.

Climate and what it means for your system

Most of Oakland has a mild, marine-influenced climate: cool summers with fog in the hills, and mild but damp winters. Heating is the main load. Heat waves are less frequent than inland, but when they come, homes without AC get uncomfortable, which is why more Oakland homeowners are adding heat pumps.

Most of Oakland falls in California Title 24 climate zone 3. The exact zone is set by ZIP code, and we confirm it for your address when we design a system.

Utilities

PG&E delivers electricity and supplies natural gas. Electricity generation is provided by default through Ava Community Energy (formerly East Bay Community Energy), 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 in Oakland are issued by the City of Oakland's Planning and Building Department. Older homes can bring extra considerations, such as replacing outdated venting or working around older duct materials, which we flag at the estimate.
