6 degrees and woke up to a dead furnace @ 3:00am. I called Mark Allen and was told the tech would be there within the hour. And hour late Adam was knocking at my door. He was very knowledgeable and was able to determine what the issue was in 20 minutes. Cutting to the chase, I am once again warm and toasty. In case you missed it, I am VERY happy with the service I received from Mark Allen.
