Last reviewed October 8, 2026 · How we research

Irvine sits in California building climate zone 8 and IECC climate zone 3B. California's design data for Irvine lists a 1% summer design temperature of 86°F and a winter heating design temperature of 40°F, a mild range where heat pumps handle both seasons well. Southern California Edison delivers electricity, Southern California Gas Company supplies natural gas, and Orange County Power Authority is the city's community choice electricity program. The City's Building & Safety division offers same-day online permits for like-for-like air conditioner replacement. The new condensing unit must stay in the same spot and at least 2 feet from any property line, and HOA approval may also be needed. Under California's 2025 Energy Code, connected ducts must be sealed and tested when equipment is replaced, and in zone 8 a new air conditioner or heat pump also needs airflow and refrigerant charge verification.
