AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · system short-cycling on/off during Irvine heat waves. Possible causes range from electrical parts (capacitor, contactor) to a refrigerant problem — all of them need a technician to diagnose.
Banging, screaming, or grinding outdoor unit
Loud bangs · metal-on-metal screaming · grinding from the condenser during Irvine summers. Possible causes include a failing fan motor, worn compressor bearings, or a damaged fan blade. Turn the system off at the thermostat and call a technician.
Furnace not igniting or blowing cold
Furnace won't ignite · heat pump blowing cold air on a 47°F night · short-cycling. Irvine's heating season is short but cold snaps still happen. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.

HVAC in Irvine, CA: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the California licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
John Wayne Airport (KSNA) is the nearest official NOAA reference station serving the Irvine area. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00093184), the area records an annual mean temperature of 64.9°F, an average annual maximum of 72.6°F against an annual minimum of 57.3°F, approximately 1,092.1 annual heating degree days against 1,074.9 cooling degree days, and an annual precipitation normal of 11.18 inches. The roughly 1:1 balance of cooling and heating degree days reflects a mild Mediterranean climate — both heating and cooling loads are moderate by national standards, and neither dominates the annual HVAC budget the way they do in extreme-climate cities.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Irvine city, California) report 111,979 occupied housing units with a median year built of 2001. Heating-fuel distribution: 60.1% utility natural gas (67,267 units), 35.6% electricity (39,810 units), 859 homes using solar energy (0.8%), and 1,549 homes using no fuel at all (1.4%). The relatively high solar and no-fuel shares reflect both the mild climate and Irvine’s master-planned community development with modern construction standards.
California Licensing Authority
California requires HVAC contractors to hold a C-20 Warm-Air Heating, Ventilating and Air-Conditioning (HVAC) License issued by the California Contractors State License Board (CSLB). The CSLB administers examinations and issues licenses statewide. Verify a specific contractor’s current CSLB C-20 license status before contracting. Primary source: Contractors State License Board (CSLB) — C-20 License.
Utility & Permit Sources
Southern California Edison (SCE) administers the Home Performance Plus program and participates in the TECH Clean California initiative for residential HVAC electrification in its Irvine service territory. Contact SCE directly for the current heat pump, smart thermostat, and central AC rebate amounts. Primary source: DSIRE — California.
