"We are very happy with the results of our door installation. The entire doorway had to be cut out and expanded to fit the standard sized doors. TME did a quick and accurate job. It looks great!"

"Victor was punctual, showed up on the day as promised, removed old fence materials, installed steel posts. Next day brought all new materials and by the fourth day all installed and left the place clean. i was impressed with the service. My wife who was concerned at first with the old fence removed but then she was happy to see the new fence in place in short time. Victor is true professional and reliable handyman/contractor. Victor also helped fixing my leaking shower valve soon after the fence installation."

"It only took a few hours and the service was professional and well done. The serviceman was highly competent and friendly. Since I had purchased the 1956 house less then a year earlier, I had questions about how the automatic sprinkling system worked which he explained to me very well.
I plan on using this company for more repairs and upgrades on this home. I would totally hire them for plumbing and HVAC work, and will!

"Josh did a great job on my roofing repair! He showed up when he said he would, and the roof looks great! He also installed some replacement skylights and siding. He sent many pics of the job as I wasn’t able to be there when the work was performed. I will definitely use him again."

"Had the absolute pleasure of meeting with Joseph at my home. I had reached out for an HVAC inspection (my wife and I just got our first home). Joseph took his time, addressed my whole system, and left me with total confidence and peace of mind on my system (we were lucky and didn’t have any issues other than some cleaning and new filter needed). I would 100% recommend Canyon City Air to EVERYONE. Truly felt like he cared for my home as if it was his. Thanks, Joseph!"
