We purchased three units from Extreme Comfort . . .and cannot say enough GOOD things about this company. Mark, the owner, is a hands on guy who overseas everything and is pretty much around 24/7 . . .On the rare occasion when we have an issue, they respond quickly and professionally, but more importantly get the problem resolved quickly. We keep a service contract on the units and they keep them clean and running well . . .Customer Service and Customer Care describes this company . . .a rarity in the business world these day. Thanks Mark, Joey, and Mike for taking great care of the DeJulius family . . .you are the best!
