Browse Forums Building A New House 1 Jul 08, 2013 10:07 am Hi all, Just wanted some advice and people's experience on putting air conditioning in a two storey house. We are in Perth and I'm not sure if evaporated is going to cut it any more. However, operating costs are a bit of a turn off when it comes to refidgerated. More importantly, what is the best combination for two storey? Is it harder to do after hand-over rather than getting the builder to do it and paying the mark-up? Your knowledge is most welcome Thanks.

My builder is allowing all of the work to be organised for refrigerated ducted but it is not part of their contract. Ciao Mark Re: Air Conditioning in a two storey home 3Jul 08, 2013 11:14 am Our refrigerated (2 story) is being put in right now, and we're at the point where the weatherboards are going up on the house. Pretty sure it's a lot easier to do during the build rather than retro fit. I would not put evaporative anywhere where you get humidity but not sure if you do in Perth.

It'll never compete with "real" aircon for cooling capability, however. There's an aircon sub-forum, you might get answers over there if you've not tried yet? As for cost of install beforehand vs afterwards; for a single-storey I'm told it's not that much different, but for a double-storey it's nearly impossible to do downstairs properly after the house is built; because they don't leave room for ducting etc downstairs. Anything can be done of course, but you might have to install lowered ceilings in certain rooms or cupboards, you might have to have odd ducting outside, unsure but it wouldn't be cheap. I can't imagine it would be any cheaper than the 20% margin the builder will charge you on getting a system installed. *edit* I've just had a thought; are there any online calculators which can give you the information you need regarding the capacity for cooling of an evaporative system? I've seen online calculators for airconditioning, so maybe you can get those calculators for an evaporative system. Re: Air Conditioning in a two storey home 5Jul 08, 2013 10:34 pm With my build I got the aircon company to design the system based on the plans then the builder has made provision for the ducting on the plans. We aren't paying a mark up, the builder is charging as an admin fee (from memory about $700) for the aircon company to install during the build. You will probably need bulkheads etc for the ducting and outlets. You can't leave it until afterwards with a two story if you have a concrete slab.
