You will be in excellent hands with Mark and Sean from Efficiency Revolution! These two will communicate like professionals be it in verbal communication, text communication, email, and in their professional appearance and composition! That is not the norm when interacting with the trades. My HVAC system had a pipe break and it was leaking water over electrical cords. This was an electrical hazard in the making. The leaky pipe was spilling water all over the play yard of my dog training facility. My team could not use the space, as the water was growing an ecosystem and the dogs wanted to lap it up like a kale fruit drink. Hello giardia! Sean noticed that our HVAC system was not sealed, so we were essentially heating and cooling the outside. They sealed what needed sealing and replaced our air filters. My understanding is that the team primarily does insulation in Denver, so they can help with that, too. Drug-free crew...no meth mouth. Hire these people. read more

I couldn't be happier with my choice to hire Mark and make this energy investment in our home. I wish we would have contacted Mark before spending thousands on HVAC upgrades, thinking that would make our home more comfortable. As it turned out, we had lacking insulation in our attic and no insulation at all in our exterior walls. Mark presented us with several options and guided us toward the option that would have the most immediate impact and fit our budget. He filed all of the paperwork for the Xcel rebate. While Xcel took quite a while to process the rebate, it ended up being substantially more than I was expecting and certainly help offset the costs improving the insulation throughout our home. Before the improvements, the second level of our 2-story home was significantly hotter in the Summer or colder in the Winter, than the main floor. Now, we have consistent temps throughout the house and are seeing lower Xcel bills too. Mark and his assistant were courteous and professional throughout the 2-day job and very Covid conscious as well, which was appreciated. Highly recommended!!! read more

Mark 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 Edwin 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. We are very impressed with the work and the next morning we already feel the difference. Thank you Mark for going through the energy credit application process with us well. HIGHLY RECOMMEND! read more

We got the attic of our 1950s house sealed up and they blew in over 17 inches of insulation. Whole project took only two days and now the house will be easier to cool and keep warmer in winter! read more

Mark and his team did a fantastic job. High quality work, fair pricing, and had a big impact on the energy efficiency of our home. Highly recommend for energy audits and improving the energy efficiency of your home. Solid investment and smooth experience. read more

Mark was great and very professional. He used to do work with Excel so he understands the rebate process inside and out, and handled all the forms for me (just had to sign). I qualified for the full rebate available to me so looks like he did a great job there! I'm blown away by the difference in temperature in our house. We went from almost no insulation in the attic to R60. Sealed all the lights and leaking areas. Sealed the doors. On a hot day (90+ degrees) our house used to get up to 85 degrees, and even as the night cooled more heat was flowing into the house. AC struggled to reduce the temperature and the summers were rough. Now the temperature stays in the 75-78 range, our AC comes on way less often and is able to reduce the temperature in the house. Pricing was in line (or lower) than the other quotes I received for anyone that is certified for the rebate. A+! read more

Mark and his team were nice to work with. The insulation, whole house fan (WHF) a bathroom fan and some miscellaneous items were professionally installed. Very little to clean up after they completed the job. The improvements made are very noticeable, since the install of the WHF, our A/C unit hasn't turned on once (we're in the middle of August as I write this review). I wish energy improvements weren't so expensive, more would be able to afford it (and help with our consumption). If you have the funds, have Mark preform an energy audit and contract out his team, you'll be happy you did. read more

Contacted this company after I found them on Angies list. They contacted me back right away, set up the appointment time for less than a week out. Showed up on time and took the amount of time he said it would. The technitian, Mark, did a great job of explaining what his findings were and recomendations, told me they would submit for the 200.00 Xcel rebate on my behalf, then e-mailed me a full review of the energy audit. Great job and would recommend them to others. read more

Mark is the best, that is as simple as I can say it. He cares to get it right and cares about making it as easy as possible for you, even filling out the paperwork for the Excel Rebates that you are eligible for and that is a huge help and time saver. Mark is very knowledgeable and takes great pride in his work, he also takes the time to explain everything he is doing and why he is doing it which is really nice. He is worth every penny, great guy! read more

Mark and his team were incredibly thorough, prompt, and accommodating, plus they handled all the rebate paperwork. I'm so glad I chose Efficiency Revolution for my attic insulation and weather proofing. What a difference Efficiency Revolution's work has made for my comfort in my old Denver house! read more

Mark is easy to work with and handles the xcel rebates that are available. I found him to be on par with the more reasonable pricing as well. I had him air seal and insulate my last home and am about to hire him for a second job now. read more

Mark and his team blew us away with their service. Our initial call for setting up an appt for a quote, the quote itself, the installation, and the final testing all went extremely smoothly and we cannot get over the difference the insulation in our attic, and air leak fixes have made on the efficiency of our A/C system. Mark got us to 46% improvement in air exchanges per hour in our house- making the difference between our brand new A/C running nonstop- to cycling on and off when it's hot and hardly coming on at all when the temp outside is under 85. His quote came in well under another company we called and he handled all of the Xcel energy rebate paperwork for us. All we had to do was wait for the check to come in the mail from them- offsetting the insulation cost immensely. His work will definitely pay for itself in the coming years with the reduction of our Xcel bill monthly. I never thought I'd be thrilled with insulation... but I really am. Thanks Mark! read more

I got an energy audit scheduled, worked from home that day. An hour before our scheduled time, Mark calls and asks me if I can reschedule for later that day. That's really inconvenient but I agree to it. Fifteen minutes past the newly re-scheduled time, he calls me up and asks if we can re-schedule for even later that day (no, I have other things planned) or another day. I say no, I don't really want to risk having this happen again. read more

All of the excellent reviews are true! I received two other quotes prior to Mark from Efficiency Revolution. He came in way under the other prices. I had my crawl space era 1975 insulated as the Master Bedroom and Kitchen/Dining room set above it. All is much warmer now. The insulators completed the job in about 5 hours. They answered any questions I had, were professional and hard working. I plan on having more work done upstairs in the Spring. I HIGHLY recommend Efficiency Revolution! read more

Mark did a nice job overall. Although I felt like there were some inconsistencies. We waited for a high efficiency fan for our HVAC system for over a month. He cited lack of correct parts (~1.5 years old), but another HVAC company came in and completed the job in under 2 hours the next business day without issue. He was also somewhat inconsistent with respect to the actual rebates that could be expected from Xcel. (ultimately I received none despite spending $1300 in upgrades) read more
