Overview of Regulations on Gas Furnaces in California
California has moved to ban the sale of new natural gas-fired space heaters and water-heating appliances, including gas furnaces, by 2030. This decision was made by the California Air Resources Board (CARB) in September 2022. Additionally, the Bay Area Air Quality Management District has approved rules to phase out gas furnaces and water heaters in the nine-county Bay Area, with a ban on the sale of new natural gas water heaters by 2027 and new gas furnaces by 2029.
Can You Still Install a Gas Furnace in California?
-
Current Installation Allowed: Currently, you can still install a gas furnace in your home in California, but this will not be possible after the respective ban dates.
-
Existing Gas Furnaces: Existing gas furnaces can still be used, serviced, and repaired, but new installations will be restricted to zero-emission alternatives like electric heaters and heat pumps.
What are the Key Details of the Gas Furnace Bans in California?
- Statewide Ban by 2030:
- The California Air Resources Board has directed state agencies to draft a rule for phasing out gas-fueled appliances, which will be up for a final vote in 2025.
-
By 2030, the sale of new natural gas furnaces and water heaters will be prohibited.
-
Bay Area Rules:
- In the Bay Area, new natural gas water heaters will be banned starting in 2027, and new gas furnaces will be banned starting in 2029.
-
Large commercial water heaters will be banned by 2031.
-
Technical Specifications and Compliance:
- The transition to electric heating solutions will require compliance with new energy efficiency standards, such as the requirement for new zero-NOx electric heaters.
-
Electrical panel upgrades may be necessary to support these new appliances.
-
Installation Costs:
- The cost of installing new electric heating systems can be significant, with a zero-NOx electric heater costing around $8,030, plus an additional $2,630 for an electrical panel upgrade if necessary.
- Rebates are available through the Inflation Reduction Act to help offset these costs.
What are the Permit and Inspection Requirements for Transitioning to Electric Heating?
While specific permit and inspection requirements are not detailed in the sources, it is likely that homeowners will need to comply with local building codes and regulations when transitioning to electric heating systems. This may involve inspections to ensure the electrical system can support the new appliances.
Conclusion
In summary, the sale of new gas furnaces will be banned in California by 2030, with the Bay Area implementing bans earlier (2029 for furnaces and 2027 for water heaters). You can still install a gas furnace in California until the ban takes effect, but the transition to electric heating solutions will require compliance with new energy efficiency standards and may involve significant costs, though rebates are available to help offset these expenses. Homeowners will also need to comply with local building codes and regulations when transitioning to electric heating systems.
