The Rinnai C4.1kW portable air conditioner is very powerful and effortlessly cools down a bedroom on a hot summers day. It's also relatively quiet. This life saver exceeded my expectations. Definitely worth the little extra money! Highly recommended!

This doesnt do much during the day in a small space. It only works over night in the bedroom once the temp outside has cooled down. Waste of money. I contacted good guys and Rinnai at the start with no outcome. Expensive and waste of money. Wouldnt buy one this expensive again. I have had a cheaper one in the past, diff brand and smaller size and it worked much better than this one. So disappointed.

Gets really cold only bad thing it's a bit loud

Very effective at cooling even a large room. For some the desire to have a proper air con system may still be unresolved with this unit, but the Rinnai has enough going for it to provide most customers a good alternative.The noise of the unit is certainly something to get used to

The unit was easy to set up and get going, cooling a large room quite effectively. Controls are easy to use and adjust. Only issue is the connection between the exhaust hose and the panel that is used with the window is not good and the hose keeps detaching.
