I got quotes for several companies including First-Call, and Reliance. Both highly advised to NOT go with the York YCD even though it was in their catalog of products. Instead they suggested using several (incredibly expensive $10k+) options. I called Tim witb Air Central through a reccomendation of a colleague. When we met I mentioned I was looking for one of those very expensuve units. I basically opened my wallet, and asked him to take what he wanted lol. His first reaction was to ask why I though I wanted these expensive units, and I explained. Instead of taking my money and running, he spent the time to go through all the reasons why the LEAST expensive options was what was best for me and my family. He literally had to sell me on not spending my money. I trusted him, and went with the York YCD and couldn't be happier.
I would trust them with my home, family, and money every time. They've proven that their concern is not maximizing how much money they can extract, but providing the right solution.
