A Complete Guide to Wall-Mounted Air Conditioning Units

If you want an easy and effective way to control the temperature in the room, installing a wall-mounted air conditioner is relatively simple and affordable.

They’re much slimmer in terms of size and they’re not as obtrusive as they once were, meaning they’re less of an eyesore in the room and more easily blend into your surroundings for a sleek aesthetic, but there’s a variety of sizes and power outputs to choose from.

The second benefit to a wall-mounted air conditioning system is that they tend to be quieter.

Types of Wall-Mounted Air Conditioning Systems

The two main types of wall-mounted units are central A/C and split systems. Both have a two-part system with an interior and exterior unit, but the difference is in how they disperse air and their installation process.

Central A/C

Central air conditioning units are comprised of one interior heat exchanger. The large unit is ideal for loft or basement installation and it delivers warm or cold air to circulate around the space. It connects to an outer component that houses a compressor and condenser, and these work to move refrigerant throughout the system which helps to spread the cold air around the room.

This type of AC system requires a way to feed the cables outside, as well as ducting and grilles. These improve ventilation and help to circulate air throughout the room, but often incur higher installation costs.

Split Systems

Comparably, split systems feature one external unit and up to 5 internal units, and if it has more than one it’s classed as a multi-split system. Aside from this, they’re pretty similar in terms of their inner workings, although they tend to be smaller which makes them the perfect choice if you’re tight on space or if the room itself is only small.

This type of system requires a hole to be drilled adjacent to the wall mounting. The cables, which are around 3 inches in diameter, need to be run through this hole so they can connect the internal and external units.

Where Can I Install a Wall-Mounted Air Conditioning Unit?

The best installation location is somewhere high on the centerline of the wall, as this will provide the most effective heating and cooling which in turn means it’s more efficient.

In terms of the room itself, you can install wall-mounted air conditioning systems in a number of different types of spaces, including receptions, offices, and hotel rooms.

The size of the space will determine the number of units you will need in total, as well as the room’s intended use. For example, small offices will probably get away with having one unit, whereas larger rooms or reception rooms might need multiple units to cover the entire area.

You could just buy one large air conditioning unit rather than having a couple of smaller ones, but these are typically louder and are thus better suited for industrial areas or warehouses where the noise level isn’t an issue.
