*$15k for a ducted system seems way over priced, unless your house is 220m2 and not insulated?

Verbal estimate from two different heat pump installation companies, about four weeks ago. I got a quote for single systems, and just asked how much whole house would cost. This is for a regular sized but very old house, about 120 square meters not counting extensions that wouldn't need anything, double glazed and fairly well insulated.

$8K seems really cheap. What brand is it, and who sold / installed it?

Wasabi? Was quoted a couple dollars short of 3k for 2.7kw Daikan - back to back install. A $1200 unit, that was one very expensive install cost.

Wasabi was one firm, and yes they are fairly expensive. Similar estimate from another firm that is generally about 20% cheaper than Wasabi for a standard install.

@timmmay was from EES, now HRV Wellington.
The unit is a Panasonic S100 PE, in a house with 4 bedrooms, lounge kitchen dining open plan.

1950s House is very well insulated in all walls, roof, floor.
uPVC with double glazing on half the house, wood frames on rest.

S100PE Unit with WiFi was $4999
Installation was $1650
Ducting and grills, $2450
Pre-inspection $150

And then they gave me a $910 discount.

$8339 Inc GST.

That's pretty good. A quick look around confirms the price of the units. I guess there's a LOT of mark-up at some places to put in ducted systems, maybe due to inexperience / low volume / because they can.

It's been useful seeing the different options people have been discussing as we are looking at similar options, especially around the Multi-split and Ducted options. I've got a few of the installers coming out to get pricing and recommendations over the next few days so that should be interesting.

I do think there is some confusion earlier in the thread about the mult-split systems. they cannot both heat and cool at the same time as some people seem to think. the wording can be a little confusing as it states you can have different temperatures set, but that won't actually send heating to one system and cooling to another. If you are expecting that functionality, I would recommend you get it in writing from the installer/manufacturer before proceeding. Fujitsu actually call it out as specifically only heating or cooling at any one time.

Seems a bit pricey for an already double glazed, insulated home. Have EES(HRV) person coming in today. Let's see how it goes.
