I have used Comfort Control Systems, Inc. on numerous occasions. They recently installed a new furnace for me. Their techs are very nice people, and they show up on time, and they do really good work. But what I really like most about the company is that they are honest and trustworthy people. I think they try to put themselves in the customer's shoes, and just do the work that is necessary. And, not just try to sell you something. I really like that about them!
