I wrote a comment about full house ducted in This Post
For me now, the ‘swampy’ is great. We have an average annual rainfall of 282 mm, less than 30 days a year where rainfall is over 1 mm, and essentially no humidity except for the rare day. Swampy is mounted next to the house at knee height, so servicing is easy, which is important given our water has a TDS of around 450 mg/L - everything gets encrusted fairly quickly.
I do have a split system for the bedroom. I’ve used it once in two years … to see if it worked.
It would be interesting to see a comparison of running costs between the various system types, including cut-off’s where certain types become ineffective (swampy’s in high humidity for example) …
