Deal with Shawn Morris and several other team members. Before Shawn, I spent time with representative from 4 other different companies (were not CoolRay). As I processed the information from each company, what I determined is that Shawn Morris had the most accurate knowledge about the various details - those details being the ones that determined that the needs I had would be fully met by CoolRay's recommended equipment. You know, the details that representatives sometime blow past when discussing - those details that, when not dealt with, mean years of minor and major aggravations - the details that make you say, I wish I had known that when I bought. I will always recommend this company and this Carrier equipment to my friends.
