The Bay Area Air Quality Management District (BAAQMD) has mandated a phase-out of NOx-emitting gas furnaces starting in 2027. In 2026, many San Francisco homeowners are proactively switching to all-electric heat pumps, which cost between $14,000 and $22,000, to avoid future compliance issues and take advantage of current electrification rebates.
A standard mechanical permit from the SF Department of Building Inspection (DBI) typically costs between $350 and $800. Additionally, California Title 24 regulations require HERS (Home Energy Rating System) duct leakage testing, which adds $150 to $300 to the project total.
Yes, homeowners can stack incentives. The TECH Clean California program offers rebates between $1,000 and $3,000 for heat pump conversions. While the federal 25C tax credit expired at the end of 2025, local PG&E and BayREN programs still provide $500 to $2,000 for high-efficiency upgrades.
The 2026 price jump is largely driven by the EPA-mandated transition from R-410A to new refrigerants like R-454B. These new systems require updated sensors and manufacturing, resulting in a 15% to 25% 'new tech' price bump compared to 2024-2025 models.
