Bellevue is in King County, which Washington's residential energy code places in climate zone 4C, a marine climate. The state code's design temperature table lists Bellevue at 24°F for heating and 83°F for cooling, the outdoor conditions a load calculation starts from. Puget Sound Energy holds the City's electric franchise. Bellevue's Development Services requires a mechanical permit even when HVAC equipment is replaced like for like, such as a furnace or heat pump, and says all new equipment must meet current codes. Permit applications and plans are submitted online through MyBuildingPermit.com, and site plans are required to verify intake and exhaust distances from property lines. Outdoor equipment also has to respect the City's noise code: Bellevue City Code Title 9.18 limits noise at the property line in residential zones to 55 dBA during the day and 45 dBA at night, from 10 p.m. to 7 a.m.

Heat Pump Installation and Furnace Replacement in Bellevue

Replacing a furnace with a heat pump in Bellevue adds an outdoor unit, and the City's rules for mechanical equipment cover it. Bellevue City Code Title 9.18 limits noise at the property line in residential zones to 55 dBA during the day and 45 dBA at night, and the City enforces it on complaint. For a new single-family home, or an addition over 1,000 square feet, Land Use Code section 20.20.525 places mechanical equipment in the rear yard, at least five feet from any property line, and equipment in a side yard outside the minimum setback must include sound screening. Washington's residential energy code, in force since March 15, 2024, does not require a heat pump when a furnace is replaced, so a new gas furnace remains an option. As of October 2026, Energy Smart Eastside, a program of six cities including Bellevue and Kirkland, lists an incentive for homeowners within those city limits and a larger bonus for households below 150% of King County's area median income, and Washington's state home-electrification program, funded by the Climate Commitment Act, uses the same income line; each program's page has its current terms.

• Bellevue noise limits at a residential property line: 55 dBA by day, 45 dBA from 10 p.m. to 7 a.m.
• New homes and additions over 1,000 square feet: mechanical equipment in the rear yard, at least five feet from any property line
