Split Air con

How much influence would cooling a landing be at cooling 3 bedrooms attached to it?
Not a massive landing, just would be a cheaper install, rather than having 3 bedrooms done.

I actually have this setup, its what the OP was about. wow it's been 5 years - well the unit is still going strong and I haven't ever serviced it or anything so there is £500 saved so far. He wanted £100 per year and as covid hit I never got it done, then never got it done.

Anyway to your question, it works great in winter as a heater, absolutely bakes the upstairs for cheap.
Summer, well it works "enough" I have to use a fan to direct the cold air but it keeps a bedroom ~20c no matter how hot it gets outside, (you gotta pick 1 bedroom haha, cant do 3!) but as others have said a huge amount of cold air just drops down the stairs so it's incredibly inefficient. Like you are thinking I did it purely for cost saving reasons and if I could go back, yeah I would 100% pick a bedroom and have it in there, There was just no good wall to mount it in a bedroom for me and I would have needed a pump for the condensate and I was concerned about the noise of that kicking on and off. (neighbour has actually complained about the noise of the outdoor unit so im sure if there was any noise in the attic overnight, I would be getting a lot of aggro from them)

As it's actually used as a heater 80% of the time, I think I got away with it, and during these little heatwaves, it makes a room perfectly cool enough to not even notice the heat.

tldr - absolutely pick a bedroom and have it in there.

Oh also! super important!! - if you have it installed to a landing (small space) and say you set it to 18c it will cool the air around it'self very fast and start throttling down, whilst in reality the bedroom your trying to cool is 25c haha. Does that make sense? it's so far away from the room your actually trying to cool, its cooling the landing then feeling smug it starts throttling down the compressor, meanwhile your sweating your balls off in the bedroom! It's not taking its room temperature from the bedroom into consideration, its taking it from where its installed.

THANKFULLY (and kinda annoyed the installer didn't explain the above to me as I would have gone straight for a bedroom install there and then) my remote control for the AC has a function where it can beam the temperature for the AC unit, so whatever room the remote is in, it beams that temperature to the AC unit, so the remote stays in a bedroom and it keeps the AC blowing cold air 24/7. As its reading the temperature of the bedroom not the landing, if it didn't have that feature I would be **** out of luck.
 
Well I’m still on the 2 units upstairs one professionally fitted and one by me I use a massive fan £40 from screw fix to circulate the air and it works I have 2 small kids and have no issues keeping the upstairs cool currently 28 degrees downstairs on the stat windows closed AC on 20 degrees upstairs in all rooms I need to look more at using in the winter and the efficiency side of things.
 
I looking to get another one in the back bedroom where my girlfriend works, This get the sun most of the morning and gets quite warm.

At the moment the hall way unit is switched on and the fan pointing in the room, Works to a fashion, Was still 26c in there last week.

They are well worth it if you ask me I couldn’t have coped with 2 little ones in this heat with them sleeping they have had good nights sleep in the hot weather I have just put the systems on a few hours before I go to bed and let the air circulate today is the first day I have just left them on tick over all day

Oh definitely, I could not cope with my office which is the opposite to my girlfriends - this get the sun in the afternoon and you slowly cook during the afternoon.
That must have been tricky with two little ones, least they can sleep cool and you can get some sleep - Hopefully!

They ‘serviced’ it when we had the second half of our house AC installed, they never appeared to do much. Haven’t bothered since. Hoover out the filters periodically and will apply this cleaner to the coils. May have it done down the line, especially for the outdoor units and those under the tree, had to unblock the drain from one of those in the winter months.

Our kitchen unit is smelling a bit when it first comes on.

Will try these cleaners:

The installer gave me a bottle of G2G-Smell-Buster when I complained about a funny smell after my units were fitted, but I've since enabled the cleaning mode which runs for a couple of hours after I turn it off and I don't notice anything anymore. I think it evaporates any leftover condensation.

I don't want to start another Air conditioning thread but I also don't want to derail this one. So maybe ignore this if it gets out of hand..

Ideally I want a split system but I wanted to install it myself. I am a avid DIYer and I'm decent at it but I know this might require a lot of stuff or a Fgas engineer to do.

I have had portable ones in the past and I hate having to port them out of the window. Defeats the object of keeping the cool air inside even with window covers...

The insane idea I have is this.

I live in a bungalow and the fireplace is not used. I considered these spot cooler air cons that I could pipe to vents in my ceiling and vent the exhaust through the fireplace in the loft. I could control this air con on a timer or app or something with very short tubes. A few metres max, any drainage tube could go out the soffit.

The only error in the idea I can think of is that the ambient temp in the loft is greater than the outside air, which I cannot pipe in. This would put unnecessary strain on the system cooling hot air. Also portable air cons obviously work from the thermostat being in the room to shut off, which is a problem.

I would ideally like a 3 port system, in out and exhaust but they do not exist. Which I think is a little strange.

Any thoughts on my stupidity or genius? Just trying to do the best I can with the little money I have.

Anyone got ducted AC? I was looking into getting AC installed in the winter this year for the upstairs bedrooms (3 of them). But I don't want those massive wall units or ceiling cassettes in each room.

I've seen you can get ducted AC, where you have a single outdoor heat pump unit. Which has refrigerant lines that go to a blower/filter unit in the loft, which can have multiple outlets. You then run ducting to each bedrooms ceiling, and just have quite a small ceiling diffuser in each room and a thermostat in each room.

Seems to be so much neater a finish. Does anyone have a similar setup?

I have a loft ducted unit! I find it works better than the individual units as they can often get too cold. The lowest temp on the ducted units are 19 so you can sleep comfortably with it on in all rooms. Only downside i've noticed is that it takes longer for the rooms to cool down, i typically turn mine on 40 mins before the kids sleep to cool down the room

Thanks, so do you have a small-ish ceiling inlet duct? Like one of these:
?

And then does every room have a thermostat?

I have a round one in each room (outlet) and 2 in the hall way (Inlet). Our thermostat is in the main bedroom which is also the control unit but i mostly just use my phone to turn it on/off

Interesting that your Inlets come from your hallway, I assumed it would just take air from the loft and filter it. But makes sense to take it from the hallway it'll likely be cleaner.

I could also put a roof vent tile and have it take input air from outside.
