"We had a great experience with the whole team. Shaun was so helpful with answering all of my questions and provided affordable estimates. Steven and Angel did great work on the install and clearly take great pride in their work, and they did a lot of work! They left the space they worked in cleaner than it was when they arrived!"
"Steven and his apprentice Angel were awesome! We are new business owners of a restaurant and our a/c went out over a busy and hot weekend. They were able to come out first thing Monday morning to diagnose and repair our air conditioner. This is a commercial unit on top of our roof, so not an easy task."
"Huge shoutout to the MileHi team that I worked with including Joni, Shaun, Steven and Angel. They answered all my questions from start to finish and made the entire process easy. The furnace install that Steven and Angel did was thorough, super clean, and professional. Highly recommend!"
