Bay Area vs the rest of the country
California's permit requirements, HERS testing, and Title 24 compliance add costs that most other states simply don't have. A permit alone costs more here than a full install inspection elsewhere.
Timeline
Why 2026 costs more than ever
Three things stacked on top of each other in the last 18 months — and Bay Area homeowners are absorbing all of them at once.
R-410A refrigerant phaseout begins
California mandated a switch to lower-GWP refrigerants R-32 and R-454B. New tools, certifications, and training — all costs passed through to the homeowner.
Federal tariffs hit HVAC equipment hard
New import tariffs — up to 145% on Chinese components — raised equipment prices 15–30%. Compressors, control boards, and motors all affected.
Federal 30% tax credit expired
The Section 25C Energy Efficient Home Improvement Credit — worth up to $2,000 — expired December 31, 2025. No replacement legislation is pending. Full cost now out of pocket.
All three forces active simultaneously
Higher equipment costs, stricter compliance requirements, and no federal offset. Bay Area homeowners are absorbing all three at once.
