Excellent – This works like a true split system, not like one of the dinky 3.5kw portable units, it works twice as well. Hard to find now. Second hand units are impossible to find, and those that are there usually disappear just as quick. No Electrical or plumbing required. If you are renting you need one of these and why ?? You can take it with you. Best of all it can be recharged if it does run low on Gas. Can't do much without a remote except turn it on and off. Customer service is a bit ordinary, they are 9-5 M-F.
