My experiences with Comfort Control Systems, Inc. have been all positive. Last time I reached out to them, it was to work on my central air system. I've been using them since the furnace was installed, which was around five years ago. They're personable, they stand behind their product, and they don't give you the run-around. They tell you what the problem is and what they're going to do about it. I highly recommend them, and if I have anything else needing to be done, I'll use them again.
