Common situation
A large living room where an outdoor unit is not possible: which air conditioning suits?
A large living room, permanent changes allowed but nowhere for an outdoor condenser, casement windows, regular summer use.
Our planner's best match
Fixed monobloc air conditioner
Fixed AC without a separate outdoor unit
This looks like the best fit because you're cooling one room, you expect to use it regularly through summer and a separate outdoor unit isn't an option.
Excellent match. No close second, and nothing important left unknown.

|---|---|---|---|
| Portable air conditioner | £250–£700 to buy | Louder indoors · Dearer to run · Less building work | Possible, not our first choice |
Why not the others
- Window air conditioner — it doesn't suit casement or tilt-and-turn windows.
- Single-split air-to-air heat pump — it needs a separate outdoor unit.
- Multi-split air-to-air heat pump — it needs a separate outdoor unit.
- Ducted air conditioning — it needs a separate outdoor unit.
What would change this?
- If you could definitely fit an outdoor unit → Single-split air-to-air heat pump £2,500–£5,100 installed
