Effective domestic air conditioning

Tried it out during short spell of hot weather. Worked well with a noticeable difference in temperature. Bought a longer hose separately to allow unit to be positioned in the centre of the room.


A really lovely unit, 4 in 1 features is amazing for all year round. It was really easy to install- the widow kit that comes with it is for sash windows, however I was easily able to buy another window kit from the likes of B&Q to fit my windows and it works perfectly. It is a lot lighter in weight and quieter than I’d thought it would’ve been - which makes it really useful within the flat.
