I own a York furnace and one day the heat cut out. I called a few shops on a cold Sunday in November to find it was a wait or I would need to pay the emergency fee. And most shops did not want to work on the York. Fire N Ice sent a guy that new his business. He changed parts that were on recall that most people wouldn't know. He changed a part that had not failed but would likely soon that was under warranty...Wow! He then fixed the valve asap...oh and then billed me less then most others quoted....PROFESSIONAL.... I have recommended them many times since.
