Burlingame does not require existing homes to give up gas, but heat pumps suit its mild climate, and the city and its power provider both make the switch easier.
WestLight Energy (formerly Peninsula Clean Energy) offers rebates for heat pump HVAC that replaces gas heating. Systems that keep a gas furnace as backup are excluded. Funds are first come, first served, so confirm terms first.
Burlingame's Building Division has waived its permit fees when a licensed contractor replaces an existing furnace or water heater with a heat pump. State fees still apply. Confirm the current policy.
