Who conditions these areas? Re: Things to know BEFORE getting a quote for AC? 11Mar 04, 2010 11:52 pm OurLindrum52 We're building and at the moment have included refrig ducted aircon by the builder. We haven't finalised our contract yet, so we still have the option to let the builder do it, or we arrange it ourselves. All we know at the moment is that the builder uses Brivis and I suspect it is the Brivis ICE add-on refrigerated cooling. Our house is two-storey and 52 squares inclu garage and alfresco. We want zoned AC as well. I'd like to get a few quotes from some cooling specialists before we finalise the building contract but I want to be prepared first. I understand the differences between standard and inverter technologies, but is there anything else I should be aware of so I don't look like an idiot? Also, has anyone installed the Brivis ICE air-conditioning and what do you think of it? Thanks in advance! Adam.R If you want indestructable and quiet then Actron with their vertical discharge for their split units is the way to go. The sound goes up, instead of horizontally and hitting the neighbour's windows. Anything with a variable speed fan in the outdoor unit (inverter, esp etc) will change the pitch of the sound and neighbours may demand a silencer built around it. The positive is that they are great when zoning is requied. Idealy get two split-ducted Actrons. One for the day zone and one for the bedrooms. That way the kids can be in bed at the right temp, with a temp sensor in the correct location (VERY important), and you can have control of your own a/c unit with your own temp sensor in the lounge room. This way the entire house can be airconditioned which is what is usually need when the kids getting to sleep, even just for the few hours that you're awake. Two sensors and therefore a/c units are essential in a two story house - one upstair and one downstairs. Keep it simple with the controls and less can go wrong. I worked on a $17M house using the above and it worked perfectly. Using only one traditional AC unit in a two storey or a large house with only one temp sensor will often lead to arguments (big temp differences between one end of the house and the other). I'd also google to see if there are recommendations or complaints posted about ac installers, and I'd get three quotes (builders do this so why shouldn't you). Also remember that you usually get what you pay for. Mech Eng Re: Things to know BEFORE getting a quote for AC? 12Mar 05, 2010 12:31 am An option that hasn't been discussed are multi-splits. More expensive but highly flexible. One large compressor feeds refrigerant to separate individually controlled AC split system units in the house. This would be also be more efficient because each room has its own return air vent so you can achieve better containment of air flow.

That's why Daikin multi splits are specified by consultants as standard for nursing homes (high wall and cassettes are self contained - ie no ducting required), but they are beyond the reach and overkill for home owners. They're great for tiny self contained units, eg nursing homes / retirement hostels. http://www.daikin.com.au/products.asp?sid=7 Mech Eng Re: Things to know BEFORE getting a quote for AC? 14Mar 05, 2010 5:25 am Adam.R That's why Daikin multi splits are specified by consultants as standard for nursing homes (high wall and cassettes are self contained - ie no ducting required), but they are beyond the reach and overkill for home owners.

It's that string thing... depends how many fancoils and the type, etc...

Re: Things to know BEFORE getting a quote for AC? 19Mar 18, 2010 8:45 pm this may be a silly question, but I'm curious how can the ducted AC work to correct temperature if there's only 1-2 temp sensors in a big 8-zone systems ? Surely there must be cases where the rooms/zones they are in are not turned on ? Re: Things to know BEFORE getting a quote for AC? 20Mar 18, 2010 9:32 pm You are right. You can only precisely control the temperature in the room which contains a sensor. The Actron Brochure makes this clear. Zoning is also not as precise as you would imagine either. The conditioned area also includes any intervening area between the zoned area and the return grille. Depends what you're current inclusions are, but we're not including wardrobes and will just use second hand ones until we can save later on to get them built.
