It has to be about twenty-five years that we have been using Comfort Control Systems, Inc. We cannot say enough about them. They are so reliable and do great work. We just had them come out to work on a gauge that went a little berserk. It was on the ceiling of the basement that controls a valve to the boiler. It was hitting up to eighty degrees in the house and it should have been stabilized at a comfortable temperature. The technician came out to replace that the gauge and everything began working perfectly. Then, within six weeks, it started up again and Comfort Control Systems, Inc. sent someone right out again immediately to take care of it. They replaced that gauge too and now it seems to be just fine. After all these years of using them, I think that says a lot for the company --and we plan on continuing to use them always. We always recommend them to our friends and neighbors. We are happy with the price they give us and think it is fair for the work that they do and that they are always quick to respond. But then again. We cannot say that based on a comparison. We are never going to use anyone else, so who would know the difference in what other companies do. We are still going to use Comfort Control Systems, Inc.!
