Ultimate Heating & Cooling installed both a new furnace and an air conditioning unit in my house. I live in an old house where the furnace goes up in the attic. They were awesome. They were very clean and careful. I had told them to be cautious about working in the attic because it could cause cracks in my ceiling. Lloyd was just sick about a hairline crack on the ceiling, but I told him it was OK and that it had probably been there from before. They were just the nicest group of guys I've ever worked with. I can't say enough good about them.
