We have done business with Comfort Control Systems, Inc. for years. We are on their annual service plan. They come out to do routine seasonal checkups on the furnace and air conditioning unit. We had them install a new furnace and last year, they put in a new air conditioning unit too. Everything is working wonderfully. We tell everyone about this company and highly recommend them. I think their pricing is pretty normal and the customer service is great. I really appreciate that they respond very quickly when you need them. They also have their technicians call ahead of time before they arrive at your home. They always take care of everything and not once has there been any problem. We will keep using Comfort Control Systems, Inc. for as long as we can.
