My wife and I first learned about Miller's Heating & Air through her doctor's office. They provided us with their phone number so we reached out to them in order to get some maintenance done on our unit. Chris was the tech who came over and he did a great job. He was very polite and knowledgeable; a super nice guy. He made everything so easy. He worked on an internal shield, along with some ultraviolet things for our system. He realized that our filter wasn't added onto his checklist, so he told me he was going to grab the right one and bring it back to us. He did what he said what he was going to do and took care of it. It was a good experience, and if we need more service on our system then we will gladly use them again.
