My company has been a faithful Carrier customer. However recently we have noticed a decrease in customer support and even worse, service parts obsolete within 5-10 years of purchase. We are now faced with adding additional chiller capacity. I believe we will consider other than Carrier. Who is the undisputed best air cooled chiller (200ton)? I noticed that the local hospital uses a German manufactured chiller. I did not notice evidence that it was frequently repaired (wire clippings on the ground, marks on the pad from refridgerant cylinders, cover screws worn from removal).
