Daikin FTW - I maintain a shitload of these units and when it comes down to the intstall price/running cost - daikin although cost a bit more when 1st purchasing the units, are far better quality than most of the other gear out there. plus the support ie parts and servicing are really good from what ive seen.
still havent had to make any warranty claim on a new daikin yet.

temperzone units are designed for commerial use.... big expensive and only become cost effective when you get into the bigger package or big ducted split types..
