Common San Jose HVAC emergencies
Call Now — (844) 582-179524/7 dispatch · San Jose-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 Jose'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 Jose, 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
Mineta San Jose International Airport (KSJC) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00023293), San Jose records an annual mean temperature of 60.7°F, approximately 2,183.6 annual heating degree days against 623.9 cooling degree days, and only 13.48 inches of annual precipitation. The 3.5:1 HDD-to-CDD ratio defines San Jose as a heating-dominated Zone 3C marine climate — but its interior Bay Area location means noticeably warmer summers than San Francisco (71.2°F annual max vs. 66.9°F), giving San Jose a real summer cooling demand that San Francisco lacks.
U.S. Census ACS 2022 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for San Jose city, California) report 326,767 occupied housing units with a median year built of 1975. Heating-fuel distribution: 58.9% utility natural gas (192,382 units), 36.1% electricity (117,943 units), and a notable 3,398 units heated by solar energy — among the highest solar-heated shares of any city in the project, reflecting Silicon Valley’s early solar adoption and the region’s climate-favorable solar economics.
Contractors State Board (CSLB)
Every HVAC contractor in San Jose must hold a California C-20 license from the California Contractors State License Board. Per the CSLB classification detail: a C-20 contractor “fabricates, installs, maintains, services and repairs warm-air heating systems and water heating heat pumps, complete with warm-air appliances; ventilating systems complete with blowers and plenum chambers; air-conditioning systems complete with air-conditioning unit; and the ducts, registers, flues, humidity and thermostatic controls and air filters in connection with any of these systems.” The classification “also encompasses warm-air heating, ventilating and air-conditioning systems utilizing solar energy.” Verifying the contractor’s active C-20 license via CSLB’s public lookup before authorizing work is the baseline due-diligence step.
BayREN
San Jose is served by PG&E for delivery of both electricity and natural gas, while Silicon Valley Clean Energy (SVCE) — a Community Choice Aggregator — is the electric generation provider for most of the city. For current rebate dollar amounts, check pge.com, svcleanenergy.org, and the BayREN EASE Home program directly — SVCE runs its own heat pump incentive programs separate from PG&E. Permit fees for residential mechanical work are set by the San Jose Planning, Building and Code Enforcement Building Division; contact the division 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.
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).
