"A prompt and thorough response, unlike simply informing me that there was nothing they could do, they actively researched the warranty on my current system (expired and void due to builder installation) before discussing a replacement option. I was then presented with several options, each accompanied by a quote. When asked, they recommended that I opt for a more economical quote that better suited my usage and requirements. I highly recommend this company. They were punctual and worked diligently, even during the peak summer months in the hottest room in my house (the attic). I will certainly recommend them to any of my friends and will utilize their services for any future needs related to air conditioning or furnace repair, as well as routine maintenance."

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!"

"In 2020 Eco Electric installed a Whole House Fan in our home. It has worked well for us and helps cool our home in the summer. Recently it stopped working. I called Eco and they sent Kyle out to diagnose our problem. Kyle was able to quickly isolate the problem to wiring in a recently installed smoke detector. He was able to fix the matter and get us back up and running. I do recommend Eco."

Boiler repairs FAQs

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350
