"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!"

"Just a "simple" ecobee install. Tech had a minor issue with my AC unit (it's 100%my unit) and didn't even attempt to upcharge us. Very honest and knowledgeable company. Will absolutely recommend to everyone I know."

"I called Marco on a Friday because we had had new counters installed in our kitchen and needed help reconnecting the garbage disposal and putting in new kitchen sink fixtures. He called back on Saturday and apologized for not calling sooner, which I thought was crazy since I had called less than 24 hours earlier on a Friday afternoon. He said he was pretty busy and offered to come by Sunday morning to help us. He showed up right on time, worked hard and even made trip to Home Depot to get the right hoses. He was great and I plan to use him again for handyman work around the house."

"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!"

"Ray is very professional, and provided options for my air conditioning unit replacement. Ray went out of his way to replace a small gas line leak that he found. He also drove to Anaheim early on Saturday morning to pick up a part that was needed for the AC unit, and came over to install it so that I would have the air conditioner available for the upcoming heat wave this week. He and his team were on time, and considerate during the installation process. I highly recommend RS Air Conditioning & Heating."
