Bill and his crew did a stellar job installing a Mitsubishi heat pump into my shop. They came in right on budget and upgraded the unit free because the one I selected was out of stock. Communication was flawless throughout the process, they cleaned up after themselves and my shop is much more user-friendly now. Thanks Bill!

Bill was great to work with, he’s a genuine, knowledgeable guy. He had great advice for our setup. I felt like I was in good hands the whole time working with him. I was shocked that this company does work in Newcastle, Wa, it’s quite a hike from Lake Stevens. Michael, Anthony, and Kaben(spelling?) installed my 3 units. There were a couple would be mistakes but this crew made sure anytime they had a question or concern to double check. This meant that everything was installed properly and those mistakes weren’t made. I would 100% work with these folks again and I’d recommend them to anyone else. Great team, great company.

Cascade Energy Services recently installed a Mitsubishi heat pump and minisplit system at my house, and I am very pleased with the experience. Bill handled the sales process gracefully and was always available to answer questions. I received two competing quotes for this service, and only Bill's ideas for how to solve the problems posed by the old house made sense. The installation team was friendly, efficient, and communicated well. They respected the space, keeping it clean and handling tricky issues effectively. I'll definitely contact Bill and his team for any future heating and AC needs.

⭐⭐⭐⭐⭐
HIGHLY recommend!!! Bill and his team are the literal best. So knowledgeable, not out to scam people out of money. He saved us money! No sales gimmicks, no pressure. Definitely calling them for all future projects. They came highly recommended by a friend, and I am so thankful we went with Cascade.

We had a nuisance popping breaker that another vendor failed to fix after replacing the breaker, and was glacially slow to respond to our requests to come back out to investigate the issue further. CES came out and was able to fix the issue. They even gave us their number so that they could come by again that same day if it started popping again.

I cannot recommend Cascade Energy Services enough. Bill and his team were professional, warm, and friendly. Their estimate on our AC install came in much lower than other companies in the Lake Stevens area. Thanks guys! Much appreciated!!

Bill and his team are going to treat you right and his tech. Anthony are so professional I will definitely use them and let anyone know if they need or want service done get ahold of them 👍

⭐⭐⭐⭐⭐
Words can't describe how great this team is. One of the last honest, trustworthy companies in the Seattle area. Bill and their team installed our tankless water heater as well as our ductless mini-split. They also did an amazing job when we later needed to add a new mini-split unit to another bedroom. They have been trusted for year in our house for the maintenance and service of those units. What you won't get from Cascade energy is an upsell to sell more product. Bill clearly cares about his team, and his team even told me about how they had a company outing to a Portland Trail Blazers game (not easy to do). Hard to find that kind of business these days who cares about their team and lets that culture trickle down to how they treat their clients. You won’t be disappointed with their team.

Thank you, Cascade! I'm thrilled with my new ductless system. Bane and Anthony were so professional, knowledgeable, and very respectful of being in my house. You could tell they really cared about the job they were doing. Cascade also gave me the lowest bid out of 3 others. And the owner Bill, super great guy!. You have exceeded all my expectations.
