Air conditioning for one room

[Thisoldheartofmine]

Not a portable unit but something else.
I have zero idea of options or what might be involved.
Can only think of a hole in the wall and some kind of box outside.
Has anyone any experience ?

We have it in our bedroom. It was pretty simple to install as only one internal unit and a shortish exhaust pipe run and we didn’t need planning permission as the external unit isn’t on an elevation visible from the street. It cost about £2,000+VAT for the unit and installation from memory; costs do go up if you need long exhaust runs, or have non-standard wall construction, or your wiring needs upgrading for the circuit etc. You also need to be mindful of where the external unit is positioned: it isn’t silent and your neighbours will probably have something to say if it’s near their own windows. We have a Mitsubishi unit but our installer said the eleqtriq iCool brand was also recommended.

For us we decided it wasn’t worth fitting throughout the house - DH works out in his garden office and on the hottest days I either go in to my company’s air conditioned office or down tools and chill outdoors. It’s just sleeping in it I can’t do.

@ComtesseDeSpair thank you !
I don't understand about the exhaust run, where does it go to and from ?

you need a pipe to take in the hot air from the room, a big noisy machine then cools some air down and sends the rest (even hotter) out of a pipe into the outside world.

so if you have a cheap portable unit, it sucks the air into the front of the machine and then pumps cool air out at the front and hotter air out through a pipe at the back that has to go out of the window.

if you have a fitted machine where the unit itself it outside, you have to have a pipe from the unit to the room to pump the cool air into the room.

My mobile unit was one of my all time best purchases even though its only used a handful of times a year, and is currently chilling the attic bedroom to arctic temperatures.However if I was doing renovations anyway I'd go for a fixed unit. There has to be a machine externally, look a bit like a heat pump but no big tubes or pipes.

Mini-splits! They heat as well as cool, so useful all year round. We had them installed 4 yars ago. Big box outside, but it's narrow and both the inside and outside are pretty much silent.

@parietal thank you for explaining
@allfurcoatnoknickers I'll have a Google.
