I started using Atlas years ago for no other reason than they were the closet HVAC company to the house I was living in. Right from the start I was impressed by both their knowledge and their willingness to explain in layperson's terms what the problem was and what my options were. I've never had cause to doubt them, they've always done exactly what they said they were going to do, and the workmanship has always met or exceeded my expectations. These guys take pride in what they do. I was reminded of this recently when I had Scott in to diagnose a problem with one of my 80's Lennox furnaces. Luckily for me, it was only a faulty wall thermostat, but since I had Scott there, I had him give both furnaces a quick tune-up, which has me hoping to get a few more years out of the old units. It's been years since I even considered calling other firms for my HVAC needs. Atlas has earned the right to be my go-to HVAC guys, and while I hope I only see them at long intervals, when I do need help, they are the people I call.
