It brings the temps down to 61 for me at lights out I run my room ar 83-84° during lights on. It is a solid built unit though Relatively quiet too for 14k btu. I chose the duel hose model because I run C02 It dehumidifies pretty well on ac mode haven't run it as a straight dehumidifier yet though. I like it because it burns off the condensate so I never have to drain it. The only thing I can say about their customer service was they answered my email questions which is decent compared to some companies out there...
