What Ducted Reverse Cycle Heating/Cooling?

Hi guys,

Building a new home and have been offered 4 quotes.

All are single phase, 8 outlet, 6 zone systems with some type of modern touchpad that operates the whole thing.

The brands I've been offered are Rinnai (DINLR12 – Max 12.7kW Cooling, 14.4kW Heating), Daikin (FDYQN 125 – Max 12.5kW Cooling, 15kW Heating), Mitsubishi (FDUA125 – Max 14kW Cooling/16kW Heating) and Fujitsu (ARTG45L – Max 14kW Cooling and 17kW Heating).

The quote for the Rinnai system is $8800 and the quotes for the other system range between $10,100 and $10,400. Really unsure why the Rinnai system is cheaper especially as the quote for it has the outdoor unit in a position at the back of the house that requires more ducting where as the others are on the side of the house.

If YOU were putting reverse cycle ducted heating and cooling in your home what brand would you go with and why? Any of those 4 brands we should steer clear of and why?

    I had LG, Mitsubishi and now I'm using Actron. They all good.

    Heating: no real maintenance required. Cooling in moist areas usually east of the great divide with lots of greenery around: Budget for periodic duct replacements! Ducts are cheap but while you have a chance ensure the layout is logical to keep future cost under control. Mildew inside ducts can really affect your health and many firms have talked me out of them because of my location. As for brands they are all a hit and miss. Go for the latest technology with single component refrigerant. 3 phase would possibly save in the very long run but you make the budget.

    Any thoughts on the Toshiba range? They seem to come close to the benefits provided by Actron (Gold standard) in the way it can ramp down to 10% of stated output, perfect for 1-2 rooms vs those systems which may ramp down to 50% of stated capacity.

    It would be good to get a breakdown on unit, ducting and installation costs to compare etc.

    what is your postcode/area? i.e. what type of weather /environment do you live in?

    •  

      New place will be in Seaford Meadows (South Australia). Fairly typical environment in terms of weather, nothing out of the ordinary compared to say Adelaide itself.

    Thats not too bad.. I got quoted $14.8k for a 3 phase Mitsubishi 17Kw system (Melbourne). Can anybody who knows about what it should be ideally priced at let me know if thats a fair quote?

    •  

      That seems pretty good. The top quote I received from my builder for a single phase 12.5kW system was $10,400. I spoke to a guy from one of the Aircon firms here in Adelaide and he said if I wanted to go from 12.5kW to 14kW I'd be looking at an extra $1K so add that again for the jump to 17kW and you're at $12,400. I was also told from multiple sources that the jump to triple phase is also quite expensive.

        Eh weird.. the guy who quoted me for the Mitsubishi first priced me for a single phase one and when I told him I require three phase, he said there isnt really a difference in price and didnt increase the cost. Also, builders usually charge a high premium on top of regular prices.

    Just make sure that it has some way of integrating with a home automation system. IR is a minimum. I got a Brivas heating system before realising it can't integrate in any way.

    Fujitsu - seems to work well hot or cold.
