Fixed-price wall mounted air conditioning unit installed as soon as tomorrow. Use code AC250 to save £250 on your order.*
Wall-mounted air conditioning systems, or split system air conditioners, comprise two different units; an internal and an external unit.
The indoor unit is mounted on the wall and the outdoor unit is usually placed on the ground or against a wall. These two units are connected through piping which is fed through the wall.
The two units work together to cool your home's air and release warm air and moisture efficiently. The indoor unit is usually very quiet, whereas the outdoor unit tends to be noisier in operation.
The cost of your AC unit will depend on a few factors:
- The type of property you live in
- The size of your house and the number of rooms you want to cool
- Extra features, like smart technology integration
- The type of air conditioner
BOXT can install a wall mounted air conditioning unit for you from £2,199, or from £31 a month. Simply answer a few questions about your home, and we'll recommend suitable units straight away.
A wall-mounted system must be installed by an F-gas qualified engineer to ensure everything is in full working order and the unit is safe to use. All BOXT AC installers are F-gas qualified.
When the indoor unit is being fitted, it should be installed as close to the ceiling as possible. This will allow for greater coverage of the room. Some manufacturers do not permit internal AC units fitting in a room with a source of ignition, ie. open fire or gas hob.
If you’re having a smart system installed, you will need to ensure that both the smart thermostat and the air conditioner can connect to your home’s wifi. Smart technology gives you greater control over your system, but to work effectively it needs to be within range of your wifi router.
Wall-mounted systems are generally considered to be one of the most energy-efficient types of air conditioners. Another benefit is that they can double up as heaters during the winter. This gives you the option of reducing how much you use your central heating system and potentially helping you save money.
In contrast, portable air conditioners are less effective at cooling your home as they take longer to cool a room and can generate unwanted heat too.
