Ryan and Katy Kirkpatrick of Wellington, CO
"We would definitely recommend having an energy audit done by Efficiency Matters.
Greg was knowledgeable, professional and honest. We really appreciated that he told us about many improvements that we could do ourselves (and exactly how to do them), in addition to completing two larger improvements for us. We found the price of these “retrofits” reasonable and workmanship excellent! As first-time homeowners, this was a great investment for us and we are very happy with the company we chose. Thanks Greg!"

Gary Zook of Fort Collins, CO
I would describe Greg as honest, thoughtful, conscientious, thorough, and hard working. I've worked with many contractors through the years and while most of them do a decent job, a few of them really impress with both their skills and attitude. Greg is one of the best and I would not hesitate to recommend him for improving the energy efficiency of your home.

Scott Rogers of Windsor, CO
Greg, I wanted to give you a follow-up on how things are working. Since yesterday was such a hot day we really got to see how things were working. I must say we are VERY HAPPY with the results. Amy said the house stayed very cool until after 7:00PM. Then the A/C came on for only a few minutes. We used the whole Hhouse fan around 9:00 PM and it cooled the upstairs 2 degrees (making the whole house the same temp). We slept very comfortably last night. This is exactly the results we were hoping for. Thank you so much!
