Dan S. came out one day, diagnosed the problem and gave me multiple solutions for correction. I ended up ordering 2 furnaces and an a/c unit. Dan gave me a great price and even re-did some duct work that was a pain in the neck. Derek, Nick R, Joe and Alex came out the very next day and installed all 3 units. They were polite, fast, knowledgeable, went over the units with me and cleaned up.
