Ducts will run under floor for downstairs, and run in ceiling for upstairs. My builder was saying either the ducts would be too long or too difficult to reach everywhere from just one unit. you do lose efficiency the longer the ducts are. Worth noting. That's why i keep saying speak to the installer (or even an installer youre not using to keep it unbiased) You wouldn't ask your dentist to give you advice for a skin disorder. I'll try to get another opinion from a different installer. I do have a second quote of one Bravis 15kw unit, but the cost is almost the same as two Daikon units. There is one guest bed downstairs and 3 beds upstairs only. The guest bed might get turned into exercise room or something. I'd assume we will have either downstairs turned on or upstairs all 3 rooms turned on if family/friends are staying.

For daytime and nightime areas Where this falls over is if for example is if you have kids who utilise the upstairs bedrooms/rumpus while adults are downstairs during the day. A very common scenario. You cant cool both zones effectively or efficiently on 16KW. I can cool the whole house (all zones on) in a 35+ degree Brisbane summers day no issue with a 16kw, with the house including some huge single glazed western windows and large void. Just standard roof and wall insulation too - nothing special. Of course you should do your own research but I reckon you'd be fine with 16kw. As stated above i'd consider ducted down and some splits for upstairs for optimal efficiency. Ducted isnt most efficient but certainly looks best, easy to control, quiet etc. How do you remove one of these ceiling air con vents? And is it possible to disconnect the duct joined to the vent from inside the house, without going into the roof cavity? 0 6586 Hi all, sorting out the ducted air con for a 350sqm double story house.
