We could not be happier with the service we got from ROX. We called less than the night before for an appointment and they had our work scheduled the next day. Our Technician Garrison was professional, a clear expert in the field and easy to talk to. He explained everything that needed to be done and all of our options. He completed the work swiftly and we couldn't be happier. I have already recommended ROX to several friends for their AC needs.read more

Jason was awesome and his estimate was very reasonable. He also spent a lot if time on the phone helping my husband make the decision of what was the best AC/furnace/water heater option for our home. The 2 guys that came and did the work were on time, friendly, and thorough when it came to explaining our new unit and its maintenance. They explained warranties and I feel confident that they will stand behind their work. I highly recommend Jason and his team.read more

Jason and his small team provide an excellent, professional service without price gouging like some of the “name brand” HVAC companies here in Denver. Trust me, when you hear those other names on the radio, you’re going to pay at least 30% more for no added value. Jason always goes the extra mile to ensure the system he installed continues to provide me and my family the quality home environmental temperatures he promised (and it very much does, always!).read more
