Air conditioning on a landing to cool bedrooms in a small semi

[bby2024]

Has anyone installed air conditioning on a landing in a small semi-detached house?

I’m thinking of fitting a single unit upstairs and leaving the bedroom doors open, in the hope it will cool the bedrooms as well as the landing. Has anyone tried this, and did it work well enough?

The ac that I have needs an outlet pipe, ideally to a window.
Maybe start with one, and if it doesn’t work shift so one is in the front and the other in the back of the house?

It might work. They usually say how much square feet they cool down.

We tried this and found it really ineffective. We find it better with ours to put it in one room for an hour or so, then move it to the other room for the rest of the evening.

We have two in upstairs bedrooms. Large 3 bed terraced. One door is permanently shut but we leave the other door open. Unit is on the furthest wall from the landing and you can feel the cool air as you walk up the stairs so it goes a long way. We’ve got Daikin Emura which cools, heats, dehumidifies and has a fan. The very best thing I have ever purchased

I reckon the problem will be that cold air sinks and hot air rises, so the cooled air will just go down the stairs I’d have thought?

This was my thought too. You’ll be constantly trying to cool down warm air rising up from downstairs.

It might work better to cool one downstairs room and sleep there during heatwaves.
