**** and his team were wonderful to work with! We hired this company to first conduct and energy audit after finding them on xcelenergy.com and ***** was very thorough. We were given a detailed but understandable explanation of our home energy audit and then we were given a quote to do the necessary updates. The best part - when they were done (yes, even the owner showed up to roll up his sleeves and work) they cleaned everything up and even took away an old house fan left in the attic behind by the new house fan installers.... read more

Mark and his team were top notch. He did an evaluation of energy use in the house, made recommendations to improve energy usage, and the team came in and did the work neatly and in a timely manner. Mark will also file the papers for the **** rebates that I qualified for. I was very impressed with their work, and with Mark checking and rechecking the work done. Communication was excellent. I would highly recommend their work.

Can’t say enough great things about Mark, he cares to get it right and in my book you can’t put a price on someone who cares. He does all the little things, from the Excel Rebates paperwork to explaining exactly what he is doing and why, he is very knowledgeable and take great pride in his work. I really enjoyed working with him, great guy.

This company is excellent; They give timely quotes, answer ?'s to your satisfaction, complete the work quickly, and clean up afterwards. One of the best contractors I've worked with in a long time. I highly recommend them for insulation work in the home, to improve overall NRG efficiency and comfort. Efficiency Revolution ROCKS!

My wife and I purchased a house two years ago in south Denver and while we were very happy with virtually everything about the home, we always noted how our upstairs was exceptionally cold in the winter and hot in the summer despite having central heating and air. Last summer, we replaced both our furnace and A/C with hopes that it would remedy the problem. It did help a bit, but not nearly as much as it should have, considering the cost of the upgrade. While our utility bills did decrease slightly due to having more effici... read more

We had Efficiency Revolution insulate our attic. Mark was extremely thorough, professional and knowledgeable from the first call until the end of the job. His crew spent over 5 hours sealing cracks, chases, insulating various openings and then blew in a great amount of insulation and reached extremely hard to get to spaces. He discovered a moisture problem and provided us with pictures of the damaged areas. Due to this problem he had to modify the job scope. He adjusted the job cost right away and was very professional and h... read more
