I just returned from Montreal attending Smardt's training, As with Multistack, Smardt is competing with companies that were in business since the 19th century, and I was impressed with how far theyve come also. The other chiller companies must be concerned. In this area the same distributer for York also distributes Smardt, they are selling more Smardt! It is interesting that a lot of the Trane offices that are not company stores are also Multistack distributers!
