Antioch, Contra Costa County

Heating and air conditioning in Antioch

Antioch grew quickly from the 1980s through the 2000s, so a large share of homes now have original HVAC equipment at or past the end of its expected life.

Homes in Antioch

Antioch has older homes near the Rivertown area and a large inventory of subdivision homes built from the 1980s through the mid-2000s. Many of those homes still have their original or first-replacement furnace and AC. Two-story layouts with a single system are common, as are attic ducts in hot attics.

Climate and what it means for your system

Antioch is one of the hotter cities in the East Bay. Summer highs regularly exceed those in central Contra Costa, and the Delta breeze arrives later in the day. Cooling is the dominant load for most homes here.

Most of Antioch falls in California Title 24 climate zone 12. The exact zone is set by ZIP code, and we confirm it for your address when we design a system.

Utilities

PG&E supplies natural gas and delivers electricity. Check your bill to see whether your electricity generation comes from PG&E or a community choice program. Rates differ, and that affects the operating cost of a heat pump compared with a gas furnace.

Permits

HVAC permits in Antioch are issued by the City of Antioch's building division. We pull the permit and coordinate the inspection and any required HERS verification.
