I need to replace my friends 3 phase unit and I’m getting him a 3phase 12kw Daikin unit, it’s 4700 just for the unit, add duct work, drip tray, supply air and return air grill, pipe work, electrical work and labour.. I’d have to say this is really quite reasonable, there isn’t a huge profit in this job.
Do you need 3 phase for ducted?
We have solar and 1 phase I’d assume. About 140m2 under roof excluding garage. Seems to be borderline between big single phase and low three phase.
The original unit has three phase power running to it, if I went single phase I’d have to upgrade the cable, not going to happen.
You don’t need 3 phase for ducted, a single phase machine will actually use capacitors to create three phase power to run the electric motor, like a variable speed drive.
Thanks. Have conflicting info from electricians / air con guys. Ducted is probably not “worth it” but with solar it’s near free to run anyway. Way cleaner than a bunch of splits even though that’s the efficient option.
A bunch of splits isn’t a bad option, it does mean you have more points of failure over the years, and they take up lots of room. A ducted unit is cleaner and neater to install, it depends on your roof space. I have solar as well, all good for the day time, but when you need it at night you’re sucking down power.
We have lots of windows so you’re looking at internal walls, or jammed right in a corner a bit ugly.
End of the day it’s quite a luxury, in southern QLD not a whole lot of the year you need cooling or heating outside ceiling fans anyway.
I got quoted $12k for ducted hvac for a 2 bedroom townhouse with three zones.
Split cycle 8.1k in one room ended up costing $5800 2 years ago.
In today's market based on everything else going up, I'd expect $6500 for the same unit now
I've had close friends recommend their tradie mate who's come over and given an absolutely terrible price, just because they're your friends mate doesn't mean they're your mate and are going to give you that same deal.
I’m sitting here wondering if hear even allowed for labour … also a HVAC expert. If this is on the table you need to jump on it. I did my own 14kw mitsi elec ducted 18 months ago and my cost was not much cheaper than this…
They can come and work for me, I'll sit at home instead!
Um, do you really want a 12kW to be wall mounted? It's quite heavy, I would prefer to put it on a poured slab.
So they are changing the outdoor, the indoor with plenums, the zone dampers, but not the ducting nor copper pipes?
Whatever. It's a great price. Add $2k for duct and pipe. Sign the cheque.
Pffft I’ve wall mounted 16kw side exhaust units, as long as it’s an appropriately strong wall. Mount 12kws with gusset’d brackets on double brick walls all day long
I mounted 14kw on the wall with heavy duty brackets and vibration elimination pads. No biggie for a 12kw and much cheaper than a poured slab or even a floating slab
I got quotes for a 10kw pre Covid (late 2019) and they weren’t even that cheap - I’d say go for it but make sure you’re comfortable with the tradesperson doing the work, find reviews and feedback online
We just got the following quote to replace the outside unit for our ducted system damaged in a storm.
SCOPE OF WORKS:
* Crane
* Reclaim gas to Government Standards
* Remove old indoor & outdoor units (take from site)
* cut out ceiling in kitchen - we do not patch hole ^^
* Install new outdoor and Indoor unit in existing location
* Fit new supply & return air plenum
* Re-use existing power circuit,
* Re-use vacuum test and flush existing pipework
* Re-use condensate drain into existing location
* Replace wall control panel with new
* Re-use zone system
* Re-use grilles and flexible duct work
* Clean filter for Return Air Grille
* Commission unit & test
* Complete customer handover
10kW - FUJITSU $9990 inc gst
As someone who installs these for a living this is a good price
Ball park on points is usually 150 a point give or take and then zones on top of that
Assuming this is a single phase unit they are about 3400 + gst this is the base model with a single fan outdoor unit it
Box of pipe for this unit is about 240 -280 for a box of 30 m I doubt the pipe run will be this big
Are older points being reused ?
If it’s ducted for ducted it shouldn’t be an issue as sizing is commonly 8” duct
As I have seen in the comments look into wifi controllers there is a bunch out there
Personally I like the Polyaire AirTouch 5 very simple and controller on the wall to on your phone is identical.
It also is considered a “smart” system with room temperature zones, ie my room to your room can be different temps and the system will automatically modulate it’s self, you can also dampen zones manually to increase decrease airflow for specific points too.
More zones = more customisation.
People on this sub jump up and down about pricing and quoting and all that kind of stuff
Yes some people take the piss but please bear in mind that heating and cooling is a rough gig it’s one of the hardest trades physically and mentally be in and we do do it to make money. It’s not great being in roofs or under floors all day but I personally love what I do.
Sorry to trail off OP.
Aircon is an investment but it’s a great one.
Proper zoning and control systems will do wonders.
Thanks mate, that's super helpful! I'll check what kind of controller this quote includes. If you don't mind I'll let you know and maybe you can give me your opinion if it's any good. I'll also enquire if he could use the polyaire
I know little beyond being able to google the sites where you can buy the parts for someone else (qualified) to install, but that seems amazing to me.
Surely a MHI 12kw ducted system is $4,000+ for the parts, let alone the effort (read: cost for someone else to do it) involved in decommissioning the existing system and installing the new.
But as I said, I’m not a fridgie, just a guy with google who has opinions on air conditioners
I think it’s the most recent gas, supposedly with lower environmental impacts and more efficient. Can’t recall exactly. All I know is that it turns into hydrofluoric acid when burnt. Which is very bad.
You’re asking if your father in law would inherently rip his own daughter off
You’re off your head man.
It’s a great price, if I was doing it (I’m a fridgie but also commercial) I’d be closer to 10k
You’re father in law has asked his mate to give a good price for essentially his daughter ( no offence but I’m sure he gives far more of a shit about her than you) and then coming on the internet to price check him like he’s some sort of prick that he wouldn’t be giving you a good deal.
If I knew who your father in laws mate is I’d be telling him to just withdraw the quote and you can get a real price and cry at how much more it will be
He's not my father-in-law's mate, I used the wording "circles" quite carefully. It's more like a mate of a mate who he had met fairly recently.
Not sure what your problem is, what are you getting so heated for?
I duno how careful you were with your wording cause it definitely reads as though the bloke is in your father in laws group of friends and doesn’t read at all like he just met him recently. Don’t add tid bits of info to make me look like I’m reading it wrong.
It’s a price barely anyone else will get. Take it ya lemon
I can only think that they work full time for someone but still have an ABN and don't turnover more than $75k on that ABN.
I'd be making sure they adequately insured aswell.
Qualified plumber here (Did 3 years of my apprenticeship as mechanical plumber which is air cons)
Sounds pretty much spot on, considering inflation I thought this would be closer to $8,500ish. But this is right on the money!
It looks good but there could be a pretty major caveat in that quote.
"Flexible ducting and refrigerant pipework cost are excluded from this quote"
Is this because you don't know what condition the ducting might be in?
Nah he checked the ducting and it was still I'm good condition and new enough that it's compatible with newer systems. His suggestion was to leave the ducting in place
recently got a quote to go into 6 zones for $12k, it was Daikin unit at the Blue Mountains. so this is a bargain.
I have Mitsubishi Heavy Industries aircond at home and they have been good so far, haven't missed a beat in 4 years.
Depending on the age of your old system, the refrigerant pipe work needs to be replaced too. If it ran on R410a, it should be fine to use the same pipes (R32 actually has some R410a in its blend), but if it’s R22 it definitely needs replacing. R22 runs at much lower pressures than R410a and R32, and will generally have been installed with pipes that have thinner walls, so if you try to run an R32 with it, there’s a good chance you’ll split the pipe at some point and lose your refrigerant charge and have to replace the pipe work anyway.
Then there’s the refrigerant oil… R22 didn’t mix great with its oil and it often hangs around in the pipes after decommissioning the system. R32 runs a different oil and could cause problems when mixed.
It’s also just a good idea in general to replace them when installing a new system if possible, because who knows what the last person has done. I know it’s better for my peace of mind not trying to use old pipe work and dealing with issues caused by it.
Thanks, thata really informative! The old system is probably from 2005/06 when the house was built and it does use R410a.
Are the pipes difficult to replace and would it add a fair bit of cost do you think?
To buy the pipe would be around $3-400, installation doesn’t usually take too long. Obviously varies from job to job, but a regular single storey house would normally only take about 15-20mins to run them in with new interconnects (the cables between the indoor unit and outdoor unit)
That price more on the normal side. This is very cheap. Also the quote states that there is an existing unit, so no pipe run, ducting and installation of diffusers etc
13k is not too bad for a 16kw
Just asking this I thought all quotes had to include GST am I mistaken? I can see that it clearly says no GST but does that mean it will be added later?
You might like to just ask what sort of cost the ducting and pipe work might be so you don't get a shock. Also, does the no GST mean they'll be wanting cash.
I had a 14kw system (Mitsubishi) replacement for about 14k inc ducts (r1.5) and 8 vents and airtouch installed for comparison, so this is definitely a good deal.
Consider getting airtouch or similar- that’s been a game changer for us being able to control things from our phone and when we’re out of the house.
We had a new system installed with 4 zones, upgraded wall controller, Daikin 7kw unit for $14,000.
That was all new ducting. I suspect they’re reusing your old ducting so bit of a time saving, but this seems better than what I’d expect for the replacement typically.
To put it into perspective, when we bought our house we only put in 6 zones, installed brand new system (no existing aircon or ducts) for about $17,000.
That’s a DEAL.
We used Seeto and they have been great. They managed to install it the day after we took possession of the house. The only “cowboy” thing tho was that they didn’t take any measurements to generate the quote and they couldn’t get the Mitsubishi in so they upgraded us for free to a Fujitsu system, which was nice. Customer support is really helpful too and def a more local, friendly, family business than a corporate monster that wants your money.
Now that I mention it… Ironically that quote looks very similar to Seeto…
But anyways, yeah $7k for ducted is them basically doing the work for you for free and probably at a loss for them. That’s a bargain. Take it.
Seems like a good deal.
Not a bad price at all
Looks good compared to what I paid for much the same thing
Try and get a controller that works with wifi
Good point here. Zone control via wifi is a game changer.
Good price
Jump on that price
Exceptional
I need to replace my friends 3 phase unit and I’m getting him a 3phase 12kw Daikin unit, it’s 4700 just for the unit, add duct work, drip tray, supply air and return air grill, pipe work, electrical work and labour..

I’m in SEQ at the moment, the humidity is horrific.
We have ceiling fan in bed in medium because dog is having a whinge, I’m under the sheet and light blanket. 25 degrees it’s basically winter! 😅
Lol, the dog having a whinge is the main reason our smaller aircon has been on for a couple of months through the peak of terrible weather.
Can’t complain too much about poverty when dog is living better than most people on the planet lol
I got quoted $12k for ducted hvac for a 2 bedroom townhouse with three zones. Split cycle 8.1k in one room ended up costing $5800 2 years ago. In today's market based on everything else going up, I'd expect $6500 for the same unit now
A cracking price, a little rude to check him considering he is your father’s mate.
What's wrong with having to double check quotes? Just because you are acquianted witj someone doesn't mean it's going to be the best price for you.
Also it does not mean that they are not retarded.
I've had close friends recommend their tradie mate who's come over and given an absolutely terrible price, just because they're your friends mate doesn't mean they're your mate and are going to give you that same deal.
Quite good
Absolutely.
Can your FiL give me a quote 😂
That is less than what a similar ducted system cost me 20 years ago.
quote not including the ducts. ducting is somewhat expensive.
I’m sitting here wondering if hear even allowed for labour … also a HVAC expert. If this is on the table you need to jump on it. I did my own 14kw mitsi elec ducted 18 months ago and my cost was not much cheaper than this…
That's pretty good value
Looks good haven't seen any ducted under 10k

They will prob use the old ducting and outlets which would save time and money.

Nope. Grab it at this price 😀
ex gst or no gst?
Can he do one for me too?
My company just paid $35k for a 5kw single cassette split system for a small room in our office. Consider yourself lucky.

Doesn't sound good at all then does it...............
Ye nah it sounds pretty fucked. It’s still being studied in terms of its risks but that won’t stop it being used for now.
You’re asking if your father in law would inherently rip his own daughter off You’re off your head man. It’s a great price, if I was doing it (I’m a fridgie but also commercial) I’d be closer to 10k

Get a comparison quote obviously
if they cant spell what they are installing then keep away
“Heavy Spit” - I hope it doesn’t!
Why is there no GST?
I can only think that they work full time for someone but still have an ABN and don't turnover more than $75k on that ABN. I'd be making sure they adequately insured aswell.
I asked that too
Good to know price of the air conditioner unit on its own . Installation costs can vary from $750 to $1500 max
this is a DUCTED system fella, not a split system.
Still expensive if ducts already in house.
Can you send the details? At that price I would consider one myself
Qualified plumber here (Did 3 years of my apprenticeship as mechanical plumber which is air cons) Sounds pretty much spot on, considering inflation I thought this would be closer to $8,500ish. But this is right on the money!
It’s a steal
Very good price, especially for post covid inflation
12kw system is around $10500. No idea why you wouldn’t get new flex and pipe work.
Because they are reusing the existing ducting from the swampy.
It looks good but there could be a pretty major caveat in that quote. "Flexible ducting and refrigerant pipework cost are excluded from this quote" Is this because you don't know what condition the ducting might be in?
Nah he checked the ducting and it was still I'm good condition and new enough that it's compatible with newer systems. His suggestion was to leave the ducting in place
Sweet deal, check the brand of the ac though.
Thanks mate, it's a Mitsubishi heavy unit
Takes the cake.. where do I sign? Lol
Sounds like they are pretty good?
Yeh daikin and mitshibishi are the top 5s
Looks good to me too.
Depending on what was wrong with old unit. It’s bad practice to reuse existing pipe work.
recently got a quote to go into 6 zones for $12k, it was Daikin unit at the Blue Mountains. so this is a bargain. I have Mitsubishi Heavy Industries aircond at home and they have been good so far, haven't missed a beat in 4 years.

Ah okay thanks, so sounds like it wouldn't be too expensive and too big a job. I might ask him if he's able to replace them
I'm paying 13k for a new 16kw system so yeah your quote is making me jealous 😭
That price more on the normal side. This is very cheap. Also the quote states that there is an existing unit, so no pipe run, ducting and installation of diffusers etc 13k is not too bad for a 16kw
they are reusing all the ductwork and piping, so don't feel too bad.
He’s making bugger all off that. There’s no way I’d do it that cheap.
This is stupid cheap
I’m sure you’ve seen the other comments by now but this is a great price, no way you’ll get cheaper
Very cheap
I’d honestly love to inspect that after install to see how many corners are cut coz damn that’s absurdly cheap
Just asking this I thought all quotes had to include GST am I mistaken? I can see that it clearly says no GST but does that mean it will be added later?
Definitely mates rates
That's a bloody great price!!! Wish I had mates rates
You might like to just ask what sort of cost the ducting and pipe work might be so you don't get a shock. Also, does the no GST mean they'll be wanting cash.
Yeah that's a decent price imo
you are going to want to find out the cost of the piping, because they will need to run new refrigerant pipes. otherwise, super cheap price
The current system runs on R410a coolant so pipes are compatible with new systems. Guy said no need to replace. Does that sound alright?
if they are 410 currently, then it should be ok, technically.
Technically okay, but not advised?
personally, I'd replace the pipes, but that's me. I'm not an expert btw. but all these things have a lifespan.
Ridiculously cheap.
I had a 14kw system (Mitsubishi) replacement for about 14k inc ducts (r1.5) and 8 vents and airtouch installed for comparison, so this is definitely a good deal.

I just got quoted $14.5k for the same thing
Yes. I paid $12k for a similar but 14kW system.
Great price
I'd ask them to quote on a Mitsubishi Electric equivalent too.
I got 10 zones mitsubishi electric WiFi touchscreen in 2021 for $10k
Did you get a 2nd quote?
