Home Comfort Alliance repairs, maintains and installs heating, cooling, plumbing and electrical systems for homes in Federal Way. Our Sumner branch covers the city, so a single call to (253) 242-5646 books a furnace or heat pump visit, an air conditioning install, a water heater swap, a stubborn drain or a panel upgrade.
Federal Way sits along I-5 between Seattle and Tacoma, with homes spread from the Puget Sound shoreline at Dash Point and Redondo to the lakes and hills east of the freeway. Our Sumner crews reach the city over SR 18, and the work runs from lakeside ramblers near Steel Lake to newer townhomes near The Commons.
One Sumner-based team handles every system in your Federal Way home. Pick a service:
Two things shape a lot of home service work in Federal Way: busy households that go through plenty of hot water, and rental homes whose owners live somewhere else. Put simply: households here run a little larger than in many nearby cities, and nearly half of homes are rented. Both facts shape the calls we get.
Most Federal Way summers are pleasant and dry. Heating carries most of the year. The exceptions are real, though: the late-June 2021 heat dome turned upstairs bedrooms across south King County into ovens. That is why so many Federal Way owners ask us about a heat pump that heats through winter and cools on the few very hot days, instead of a separate air conditioner.
Homes near the water at Dash Point and Redondo face salt air, which is hard on outdoor coils and electrical connections, so we look closely at those parts when we work near the shoreline.
Puget Sound Energy supplies electricity and natural gas across Federal Way, and Lakehaven Water and Sewer District provides water and sewer (City of Federal Way, Who Do I Contact). As a PSE customer, you may qualify for:
Home Comfort Alliance is a PSE Trade Ally contractor for HVAC and water heaters, and we handle the rebate paperwork. Details are on our PSE rebates page.
The City of Federal Way’s Permit Center issues building, electrical, mechanical and plumbing permits, and residential electrical, mechanical and plumbing permits can be filed online through MyBuildingPermit (City of Federal Way, Permit Center). Federal Way is one of the Washington cities that inspect their own electrical work instead of leaving it to L&I (L&I, cities that do their own electrical permits). We pull the permits our work needs and book the city inspections, so you do not have to.
Federal Way has a lot of rental homes, and some owners who call us do not live at the property. When you book, tell us who should receive the written price and who will let the technician in. Nothing beyond the diagnosis goes ahead until the person paying approves it.
Typical rental jobs include water heater replacements, wall heater and baseboard problems, clogged kitchen drains, and furnaces that need a tune-up before a new tenant moves in.
We cover all of Federal Way, from Twin Lakes and Dash Point in the northwest to Redondo on the shoreline, the Steel Lake and Lake Killarney areas, the neighborhoods around the city center and the Performing Arts and Event Center, and the former Weyerhaeuser campus to the east. Crews reach the city from Sumner on SR 167 and SR 18, and we also work in nearby Milton, Des Moines and Fife.
