We Love Our Customers!

Looked at five different companies for a new furnace and AC, Cascade Energy was the best price and Bill’s explanation of the whole process was very thorough. Was able to schedule installation in a very timely manner and everything was installed on time, very clean. Thank you.


Shoutout to Bill for a job well done. He was the last of the 4 bids we got for installing Tankless Water Heater and we hired him right away. His quote was the lowest and explained everything we needed to know about the product. Very honest and knowledgeable. Definitely recommended. Thank you Cascade Energy Services.


Flawless service! Bill Mugrage and his team are true professionals and were a pleasure to do business with. From the quote to the finished product it was conducted with the best interest of the client. Couldn’t be happier.
