Indicative ranges, not a quotation. Pipe length, condenser position, drilling and the electrical scope move the final number more than the unit does. Across a province this size the ranges above hold reasonably well for domestic work in the metros. What moves them is distance on outlying jobs, and the scale of the plant on anything commercial or industrial.

Compare Local QuotesWhat Drives Aircon Work Here
Gauteng is small in area and dense in demand. Almost the whole province is within an hour of a competent contractor, which is not true of most of the country. What that means in practice is you should be comparing several quotes rather than accepting the first, on price and on what is actually included.
Altitude runs through everything. The whole province sits between roughly 1,300 and 1,750 metres. Thinner air moves slightly less heat for the same airflow, which is one reason borderline rooms here are better served by the next size up.
One long dry season, then storms. Months without rain from about May leave outdoor coils packed with dust, and then the summer storms arrive with hail. Both cost cooling capacity, and both are cheap to deal with in advance and expensive to ignore.
An unstable supply. Load shedding and the surges that come with restoration are the most common cause of control board failures on this plant. A time-delay relay and a surge arrester cost a fraction of a PCB.
Commercial work spread across nodes. Office parks, retail centres, warehousing and data rooms sit in clusters from Centurion and Midrand through to the East Rand. That work is contract maintenance with recorded readings rather than an annual clean.
Response Times and After-Hours
Coverage across Gauteng is good, and the practical question is which contractor is genuinely close to you rather than whether one exists. On urgent commercial work in particular, ask where the contractor is based and what response window they will actually commit to before you appoint.
If water is running out of an indoor unit, switch it off at the isolator before anything else. The water damage almost always costs more than the repair does.

Frequently Asked Questions
Does Pretoria’s altitude affect what size aircon I need?
Mildly, and it is worth knowing about. At roughly 1,350 m the air is thinner than the sea-level conditions a unit is rated at, so the same machine moves a little less heat for the same airflow. Nobody applies a formula to it on a domestic job, but combined with how hot Pretoria afternoons get it is one of the reasons a borderline room is better served by the next size up than by the smaller unit on the spec sheet.
Why do the filters and coils clog so quickly?
Dust, mostly. Between roughly May and September there is no rain to settle it, and what the wind lifts off open ground, roadsides and construction ends up on your filters and coil. Indoor filters want rinsing monthly through that period rather than at a service interval, and the outdoor coil wants a proper wash before the heat arrives.
Does hail damage outdoor units?
It does, and Gauteng hail is the reason this comes up here and not in most of the country. Hail flattens the aluminium fins on the condenser, which chokes airflow across the coil and pushes head pressure up until the unit starts cutting out on hot days. Light damage can be combed out, heavy damage means a new coil. A guard costs a small fraction of either.
Does load shedding damage an aircon?
Two things do the damage, and neither is the outage itself. Repeated hard restarts are hard on a compressor that has not had time to equalise, and the surge when supply comes back is a very common cause of control board failure. A time-delay relay and a surge arrester on the circuit deal with both and cost far less than a PCB.
Can I use the aircon for heating in winter?
Most inverter splits sold here are reverse-cycle and heat perfectly well. Pretoria winters are milder than the Reef, but June and July mornings still sit close to freezing, and running a unit in heating mode costs a fraction of what a bar heater does for the same room. Ask whether the model you are quoted heats, and how it behaves on a cold morning when it has to run a defrost cycle.
Is Pretoria hotter than Johannesburg?
Noticeably, and it matters for sizing. Pretoria sits lower and in a valley, so summer afternoons commonly run a few degrees above the Reef and the heat lingers into the evening rather than dropping away. A unit specified off a generic South African sizing table tends to be about right in Johannesburg and slightly small in Pretoria.
