At Home Comfort Alliance, we provide expert HVAC, plumbing, and electrical services to homeowners across Seattle, Tacoma, Bellevue, Everett, and the entire Puget Sound region. Our licensed technicians deliver 5-star service, upfront pricing, and energy-efficient solutions you can trust. 🏠 Heating & Cooling: Furnace & AC repair, installation, heat pumps, ductless mini-splits, and air purification. 🚿 Plumbing: Water heater replacement (tank & tankless), drain cleaning, leak repair, and repiping. ⚡ Electrical: Panel upgrades, whole-home rewiring, generators, surge protection, and smart home systems. As a locally owned Carrier Factory Authorized Dealer, we’re known for honest service, premium products, and fast emergency response—keeping your home safe, comfortable, and efficient all year long.

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself. I will not be using G&S Heating again."

"Here’s a version of the review tailored for Angie’s List: Amazing Experience with Finish Line Home Services LLC! We had a major issue with a septic backup in our bathroom, and during the cleanup process, asbestos was discovered. Our bathroom was completely destroyed and needed to be rebuilt from the ground up. Derek and his team at Finish Line Home Services LLC were incredible to work with every step of the way. Derek took the time to explain all of our options thoroughly, ensuring we felt confident in the decisions we made. He provided a detailed quote within a day, and his team’s work was nothing short of amazing. The finished bathroom is beautiful, functional, and so much better than we could have imagined.

Washington Energy Services has been helping homeowners throughout Western Washington save money and live more comfortably since 1957. As one of the largest home improvement companies in the Seattle-Tacoma area, we are able to provide you with top-quality products and services, installed by our professional craftsmen. Our free in-home estimates ensure you get the right product for your home. We'll be with you through all aspects of your project from the purchase decision, expert installation, quality maintenance and service, and even warranty work should you need it. We assist with permits and rebates, too. Give Washington Energy Services a call today to learn more or to schedule your service.

"This review is long overdue in my praise of Washington Energy Services for their customer service, pricing and workmanship ! My first interaction was in 1999 when they installed windows throughout my house. They are still in excellent condition. I might note I called them over 20 years later to inquire on how I could repair a broken slider and they sent someone right out, charging a very nominal amount to repair it. In 2020, I needed to replace my hot water tank, and the extremely knowledgeable Christy presented several options, answering my many questions. I settled on one with a booster that seemed to best fit my needs. Finally, in December 2023, I purchased a new gas furnace from WES. I had a minor issue with a fan switch and they responded quickly to rectify the situation. Within the past two months, I seemed to be having an issue with my thermostat (something they had not installed), and the manager, Greg, came out twice with his crew to explore the problem. Today they installed a new thermostat FREE OF CHARGE! Their excellent response and customer service is beyond any company I have hired. And I particularly love that they are family owned and have been around for decades. Their employees seem to be there for the long haul, which speaks highly of the owner. I refer all my friends and family and I won't go anywhere else for services that they offer. Many thanks to the staff I have interacted with over the past 25 years!"
