Guides for Johannesburg homeowners and landlords

These guides explain aircon decisions in plain language: what moves an installation quote, what size a room needs, the difference between an inverter and a non-inverter unit, how often to service, and why a unit stops cooling. They are written for Johannesburg conditions.

We do not publish prices or figures we cannot source. Where a number would matter, we explain the factors behind it, or point you to the published source.

What size aircon do I need?

There is no useful answer to this question without the room in front of you, and any figure quoted over the phone is a guess. This guide explains what actually decides the size, so you can describe your room well enough for a contractor to advise properly.

How often should you service your aircon?

There is no single number that fits every unit, because the answer depends on where the unit is and how hard it works. This guide explains how to work out the rhythm your own aircon needs.

Why your aircon is not cooling

A unit that runs but does not cool is one of the most common calls a contractor gets, and it has several possible causes. This guide explains how the symptoms differ, so you can describe yours accurately.
