I have the 1/3 hp prime tower and it for one is very noisy. (it's in my living room) It started working very erratic lately...running for hours, then on two minute off for five... customer service helped to tell me I needed an a/c guy to come out. Had that done and still was not right. We added another fan in the canopy and helped a lot, but then a piece of plastic broke that is "non-replaceable" and now we need to buy a new one according to customer service. The chiller is only 1 1/2 years old.
