A wall mounted air conditioner offers a more permanent cooling solution for the parts of your home that aren’t connected to the central heating. There’s a lot of variety to choose from with a split air conditioner, such as our selection of split system air con units over £1,000. The most important thing to consider with a wall mounted air conditioner is the BTU rating. The BTU rating is a measurement of how efficiently the split air conditioner can cool down a room. A BTU rating of 8,000 is good for a small room, while a large area would need something like 18,000 BTU. Look through our selection to find the AC for your needs.
