EXCELLENT Based on 301 reviews Posted on Katherine DinesTrustindex verifies that the original source of the review is Google. Our furnace started making a horrible sound. Steven Holstein came out and it took exactly 1 minute for him to discover what was wrong. The first guy didn't even get the serial or model number, and only said, "it might be the wheel bearings and it might be fine for a day or could last another two years." Thank you Steven for your friendly professional service.Posted on Emily DiamondTrustindex verifies that the original source of the review is Google. Chris and Steve did an excellent job on the HVAC in our house! We replaced an existing system that wasn’t heating properly and in just a few days we had an incredibly powerful system up and running. They were both professional and helpful throughout the whole process. Highly recommend.Posted on ForeverieTrustindex verifies that the original source of the review is Google.

Steven, Angel and Joanie were absolutely amazing! From the initial inspection to the final installation, they were professional, courteous, and efficient every step of the way. The entire process—from quote to completion—was exactly as promised. It’s rare to find technicians who are this reliable and transparent. I highly recommend them for anyone needing HVAC services. Great job, Steven, Angel and Joanie!Posted on Gantuya BrownTrustindex verifies that the original source of the review is Google. It was easy to get an appointment scheduled and Alan was very friendly and knowledgeable. He was able to identify an issue with my furnace and get it fixed. Thank you for prompt service! I will keep going back to this company for my HVAC needs going forward. Solid people.Posted on richard linquantiTrustindex verifies that the original source of the review is Google. For the purchase of a heat pump hybrid hot water heater, I went to 3 local companies for information and estimates. The best in every way was MileHi HVAC on S. Broadway in Denver. They installed my new Rheem Professional today. Their cost was thousands lower than the big plumbing company and a considerable savings from the middle bid. But that was only the icing on the cake. The plumbing tech, Steve, was the only 1 of the 3 who seemed to understand the technology and limitations of the type of heater I specified. His explanations were clear. He was the only 1 to point out that the plumbing pipe upgrade that big company said I needed because of new building codes was unnecessary because the pipe was a vent to the outside for my old GAS heater. Steve answered my questions without dismissing the technology I was interested in and trying to sell me something else. Scheduling was easy and fast. MileHi also handled the electrical installation of a 240 volt line, and pulled permits for the electrical and plumbing work. MileHi knew without prompting how to get me the Xcel Energy rebate ($2,250!) for my new heater. Steve, and Tracy at the office, were responsive and pleasant to deal with.Posted on M MazzaTrustindex verifies that the original source of the review is Google. Steven and Angel arrived on time. They went above and beyond to solve my furnace issue. Steven was knowledgeable and friendly and he took the time to answer all my questions and concerns. Angel was a hard worker and polite apprentice. When they were done Steven vacuumed and wiped down the furnace! They also wore Shoe covers! Appreciate it! Joni thank you for sending your best technician the next day after my call. You were very helpful trying to accommodate my request. I very much appreciate it. Highly recommend MileHi HVAC !Posted on Matt McClainTrustindex verifies that the original source of the review is Google.
