Common San Francisco HVAC emergencies
Call Now — (844) 582-179524/7 dispatch · San Francisco-area network
AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · ice on the refrigerant lines · short-cycling on/off. The most common cause is electrical (capacitor, contactor) or refrigerant — both require a technician.
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. If you smell gas, leave the building immediately and call 911 first.
Banging, screaming, or grinding outdoor unit
Loud bangs · metal-on-metal screaming · grinding or rattling from the outdoor unit. Failing fan motors, loose blower wheels, and worn compressor bearings are the usual causes. Turn the system off and call — running through these noises spreads the damage.

San Francisco's marine coastal climate & your HVAC
This Zone 3C (Warm-Marine) climate splits the year between heating and cooling load. Federal SEER2 14.3 (Southwest Region) minimum applies to new AC equipment. Heat pumps that handle both heating and cooling from one outdoor unit are an increasingly popular choice.

HVAC in San Francisco, 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
San Francisco International Airport (KSFO) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00023234), San Francisco records an annual mean temperature of 58.7°F, approximately 2,475.4 annual heating degree days against only 200.2 cooling degree days, and 19.64 inches of annual precipitation. The 12.4:1 HDD-to-CDD ratio is among the most cooling-minimal of any major U.S. city — San Francisco’s marine climate almost never demands refrigerant cooling, which is why tens of thousands of SF homes operate year-round without any central AC system.
U.S. Census ACS 2022 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for San Francisco city, California) report 362,650 occupied housing units with a median year built of 1945 — tied with Detroit for the oldest housing stock of any major U.S. city researched. Heating-fuel distribution: 56.0% utility natural gas (203,069 units), 34.7% electricity (125,802 units), and a striking 5.9% of units reporting no fuel used for heating (21,477 units — an unusually high share reflecting SF’s mild marine climate where passive envelope performance plus space heaters often suffice). San Francisco’s pre-war Victorian and Edwardian row houses often have no central ducting and no central AC — both additions have historically not been necessary.
BayREN
San Francisco is served by PG&E for both electricity and natural gas, and residents have access to regional incentives through the Bay Area Regional Energy Network (BayREN). Per the BayREN EASE Home program page: “EASE Home covers 80% of the cost for core upgrades, such as insulation and duct sealing. You pay just 20% of the total project cost, with your contribution capped at $1,000.” For current PG&E residential rebate amounts (heat pump, smart thermostat), see pge.com directly. Every HVAC contractor working in San Francisco must hold a California C-20 Warm-Air Heating, Ventilating and Air-Conditioning contractor license from the California Contractors State License Board. Permit fees for residential mechanical work are set by the San Francisco Department of Building Inspection (DBI); contact DBI directly for the current fee schedule. The federal Section 25C tax credit was terminated for installations after Dec 31, 2025 (OBBBA, P.L. 119-21) — the local incentives above remain active for 2026.
PG&E, DSIRE, SF Department of Building Inspection (DBI)
San Francisco homeowners served by PG&E may qualify for savings through PG&E TECH Clean California when installing qualifying high-efficiency equipment. State HEAR rebates and utility programs remain the active federal-funded path in 2026 — the federal Section 25C tax credit was terminated for installations placed in service after Dec 31, 2025 (P.L. 119-21). Primary source: DSIRE — California.
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). State HEAR rebates and utility programs remain in effect. See our HVAC financing options for what's still available.
