Community❓Common Questions
As of January 1, 2026, San Francisco sellers must disclose the presence of gas appliances and potential future costs for electrification. While a full ban on new gas furnace sales doesn't start until 2029, many homeowners are opting for heat pumps now to avoid future retrofitting costs, which can add $10,000 to $50,000 if a main electrical panel upgrade is required.
The premium is driven by three factors: San Francisco's high labor rates (averaging $91-$144/hr for skilled techs), strict Title 24 energy standards requiring 15+ SEER2 equipment, and mandatory HERS performance testing which adds $150-$400 to every project.
Homeowners can claim a federal tax credit of up to 30% (capped at $2,000 for heat pumps). Additionally, local 'decarbonization' programs and PG&E offer rebates ranging from $115 to $1,000 for high-efficiency Energy Star units, potentially reducing the net cost by over $3,000.
A ducted heat pump system typically ranges from $12,000 to $22,000. However, if your home has an older 60A or 100A electrical panel, you may face an additional $2,500 to $5,000 for a panel upgrade to support the increased electrical load.
