New Homes: Heat Pump Required
If you build a new home in California, a heat pump is now the default. The 2026 code makes gas furnaces very hard to use in new builds without a large trade-off elsewhere.

California Gas Furnace Phase-Out: What Sacramento Homeowners Need to Know
You may have read that California is banning gas furnaces. The real picture is more narrow. The Title 24 2025 code, active since January 1, 2026, requires heat pumps in new homes. Gas furnace swaps in homes that already exist are still legal in 2026. Rules may shift after 2030. Fresh Air gives you a straight read on what applies to your home right now.
Existing Homes: Gas Still Allowed
If your furnace fails and you need a swap, gas is still legal in 2026. You must use at least 92 percent AFUE in most Sacramento zones. Fresh Air installs models that meet this rule.
The 2030 Rule
California plans to ban new gas furnace sales after 2030. Swaps in existing homes will not be an option after that date. A heat pump installed now lasts 15 or more years and beats the deadline.

Gas Furnace vs. Heat Pump for a 2026 Sacramento Replacement
If your furnace fails today, you have two choices. Swap with gas at 92 percent AFUE, or step up to a heat pump. The gas swap costs less upfront and is simpler. A heat pump costs more but gets rebates and runs on power, which shields you from gas price swings. Fresh Air shows you both numbers at the estimate so you can choose with full info.
The 2030 rule matters for planning. A gas furnace put in today will likely reach end of life around 2040 to 2045, after the phase-out date. A heat pump put in today lasts the same span and gets today's rebates. Fresh Air does not push you one way, but we share the timeline so you can plan with clear eyes.

California Gas Furnace Phase Out 2026 Sacramento FAQ
Can I still swap my gas furnace in Sacramento in 2026?
Yes. Gas furnace swaps in existing homes are legal in 2026. You must meet the 92 percent AFUE minimum in most Sacramento zones. Call Fresh Air for a swap estimate.
Does the 2026 code force me to get a heat pump?
Not for swaps. The new code only requires heat pumps in new homes. Swaps in existing homes are not subject to that rule in 2026.
What is the 92 percent AFUE rule?
AFUE measures furnace efficiency. A 92 percent AFUE furnace turns 92 cents of each gas dollar into heat. This is now the minimum for most residential gas furnace swaps in California.
