18,000 BTU Air Conditioners in South Africa: Prices & Specs

With so many 18,000 BTU air conditioners in South Africa, it can be tricky to choose a brand and model to suit your needs.

To make this easier, we’ve compiled a guide to some of the best and most affordable 18,000 BTU air conditioners, with prices, specs and key features.

What does BTU mean in relation to air conditioners?
BTU is short for British Thermal Unit. It measures the amount of heat an air conditioner removes from a room within an hour.

How big an area will an 18,000 BTU air conditioner cool? 

An air con of this size can cool areas of up to 32 quickly and efficiently.

A quick rundown of air conditioner types    

In South Africa, air conditioners are divided into five broad categories – inverters, non-inverters, split units, cassettes and under-ceiling units.

The first two categories – inverters and non-inverters – are defined by the type of compressor motor in use.

Inverters have variable speed compressors that automatically adjust to regulate the temperature. These types of air cons are more energy-efficient and provide consistent cooling and heating.

Non-inverters have fixed speed compressors. Motors turn on and off at regular intervals to maintain the desired temperature. Power usage is higher, but the initial cost of the unit is lower.

Split units, cassettes and under-ceiling units have different designs.

Split air conditioners are typically wall-mounted and have neat, horizontal lines. These types of air cons are compact, unobtrusive and efficient at cooling smaller spaces.

Cassette air cons are larger and square. The interior unit is mounted inside the ceiling, with only the front panel visible. Cooled air is distributed through central vents, as well as the sides. Cassettes are suitable for cooling large spaces – retail stores, hotel lobbies and clinics.

Under-ceiling air conditioners are mounted underneath the ceiling. They have flat horizontal profiles similar in style to split units but are typically larger and more powerful. These air cons are ideal for residential and commercial applications.

Split, cassette and under-ceiling A/Cs have two “split system” components – one is mounted indoors and distributes the cooled air. The other is installed outdoors and consists of the compressor motor.

All three designs are available as inverter and fixed speed non-inverter configurations.

Best choice for quick, efficient cooling 

The signature feature of the XA51 is the speed at which it cools a room. Five speed settings, coupled with an AI inverter algorithm, provide maximised air flow that’s temperature regulated according to ambient conditions.

As well as a range of energy-efficient and convenience features and functions, the remote-controlled split-wall mounted unit is elegantly styled and competitively priced.

Best 18,000 BTU non-inverter air conditioners

Light on the pocket and with fewer working parts, non-inverter air conditioners are easy to repair and maintain. They’re the ideal solution for cooling larger spaces – in the home and work environment.

Best choice for low-cost cooling

It’s the ideal heating and cooling solution for budget-conscious South Africans. The unit comes with a full-function remote control and five-year compressor warranty.

Best 18,000 BTU cassette air conditioners

With low-profile designs and multi-air-flow capabilities, these cassettes are great for providing discreet yet effective all-of-room air conditioning.

Best choice for cooling “inner sanctums”

The Arctic is ideal for cooling spaces where the distance to the exterior of the building – and therefore the outdoor unit – is great.

It has a powerful inverter compressor motor and three fan speeds capable of distributing cooled air over long distances.

The neat flush-to-ceiling design, and the fact that it uses more environmentally-friendly refrigerant, ensures this unit by Alliance takes top billing in the best 18,000 BTU cassette category.

Best choice for powerful, small space cooling 

The 4-Way Mini offers maximised air distribution without a hint of a draught. Air flows through vents on all four sides of the unit, plus thousands of micro-holes punched into the grill.

This air con is 50% more energy efficient than a non-inverter. It also has a lower carbon footprint due to the addition of fluorinated greenhouse gas to the refrigerant. 

Samsung’s mini cassette is the small-space solution for environmentally-conscious South Africans.
