HVAC, plumbing and electrical service in Duvall, WA
Home Comfort Alliance repairs, replaces and maintains heating, cooling, plumbing and electrical systems for Duvall homeowners, with service scheduled from our Redmond branch. One company handles the furnace, the heat pump, the water heater and the electrical panel, so projects that touch more than one trade are planned together.
Duvall sits on SR 203 in the Snoqualmie Valley, halfway between Monroe and Carnation, and had 8,034 residents at the 2020 census. The city grew fast as a bedroom community, with its population rising about 280 percent in the 1980s and another 67 percent in the 1990s (Duvall, Washington (Wikipedia)). Many of the furnaces, water heaters and electrical panels installed in that building wave are now at or past their typical service life, which is why replacement questions come up so often here.

What Duvall homes need from their heating, plumbing and electrical systems
Three local conditions shape most of the work we do in Duvall.
- Homes from the 1980s to 2000s growth years. A gas furnace usually lasts 15 to 20 years and a tank water heater 10 to 15. Houses from Duvall’s growth decades are often on their second furnace or water heater, and many still have the original electrical panel, which may not have room for a heat pump, EV charger or induction range.
- A valley that floods. The Snoqualmie Valley around Duvall is subject to flooding from late fall to early spring (Duvall, Washington (Wikipedia)). On lower properties we look at where the outdoor unit, water heater and electrical equipment sit, and whether a crawlspace or garage location puts them at risk.
- PSE electric and natural gas. Duvall homes are on Puget Sound Energy, and many heat with PSE natural gas. That opens specific PSE rebates for switching to a heat pump or pairing one with your furnace.
Neighborhoods we work in include downtown Duvall along Main Street, the homes around Lake Rasmussen just east of downtown, Cherry Valley, and the hillside subdivisions above the valley floor.
Duvall rebates and incentives (updated September 2026)
