Aircon installation
A new split unit for a bedroom, a lounge or a small office, or a replacement for one that has given up. Sized for your room, not for what's on the shelf.

Six short fields. These details let us call back with the right information.
The short answer
Aircon installation, repair and service in Gauteng starts with one request. Tell Aircon24 what your aircon needs and where you are, in Johannesburg, Pretoria, Centurion, Sandton, Randburg or Midrand. We call you back to go through the job and confirm the price and scope. You'll know both before you agree to anything.
Four jobs, one place to start
Pick the job closest to yours. Or skip the picking and describe it in your own words in the form.
Aircon repair
Not cooling, leaking water, noisy, tripping the breaker. Start with the symptom, see what you can safely look at yourself, and know when to stop.
Aircon service and maintenance
Filters, coils and the drain looked at before the hot months, not after the first breakdown.
Regas and leak repair
For split units in homes and offices, not car aircon. Refrigerant is not used up in normal operation. A low charge can result from a leak or an incorrect previous charge, so the cause needs diagnosis before refrigerant is added.
Not sure which one you need? The services overview has a short guide that starts from what the unit is doing.
Thinking about an inverter unit because of load-shedding? Read the inverter aircon guide first.

A proper installation is more than a unit on a wall
A cheap quote and a good quote can both say "installation". What matters is what sits behind the word. Here's the checklist to hold any quote against, ours included.
- Check the size was worked out from the room, not the floor area alone. Sun, glass and ceiling height count too, so ask how it was chosen.
- Look for a level bracket and a clear spot for the outdoor unit, with room to reach it when it needs a service.
- Refrigerant pipes need the specified insulation. Cables and drainage should be supported and routed correctly, with a suitable fall for gravity drainage.
- The connected pipework is leak-tested and evacuated of air and moisture following the manufacturer's procedure before the system is charged or opened to refrigerant.
- The charge gets set and the unit gets run. Ask that someone switches it on and checks it cools before leaving.
- Have the supply, circuit protection and isolation arrangements assessed for the unit and the manufacturer's instructions.
- Expect a handover: how to run it, and how to clean the filter the way the manual describes.
Two jobs that need a registered person
Work on the refrigerant circuit needs an SAQCC Gas registered practitioner. A new electrical circuit needs a Certificate of Compliance from a registered electrician. Ask who will do each part. And keep your hands off refrigerant lines and wiring: that's not a Saturday job, and outdoor units on high walls are a fall risk.
What does it cost? Published prices differ, and a fair number needs the job details
A reliable installation price needs the job details. The room, the pipe route, the wall and the electrics all move the price. What we can do is show you what others publish, so you know what's in the same ballpark. These figures are theirs, not ours, and each one carries its own date.
| Source | What it lists | Published figure | Date |
|---|---|---|---|
| Blue Line Air | 12,000 BTU split, unit, brackets and standard piping included | From R7,999, with extra costs possible | Page dated 2 Jul 2026 |
| Flowleads | 12,000 BTU, supplied and installed, lounge or bedroom up to 25 m2 | R9,500 to R14,000 | 3 Jun 2026 |
| ServiceLink SA | 12,000 BTU, unit plus labour | R7,500 to R13,500 | Published 16 Feb 2026; prices labelled Q1 2025 |
| The Handyman Johannesburg | Labour only, back-to-back split | About R1,500 for a simple job; more complex ones start around R2,000 | Undated; accessed 9 Nov 2026 |
They don't agree, and that's the point. Brand of unit, pipe length, wall type and electrical work all sit inside those gaps. Read the aircon installation cost guide for what moves the number and for each source's own date.

Questions people ask
Should I repair my aircon or replace it?
Ask for a repair quote and a like-for-like replacement quote. Compare scope, unit condition, repeated faults and whether it is correctly sized. Start with the aircon repair page to see what's likely wrong.
How long does an aircon installation take?
It depends on the job. The installers we cite give different estimates: roughly two to three hours for some back-to-back jobs (ServiceLink SA) and three to five hours for a standard single split (Aircon Master, ServiceLink SA). The Handyman Johannesburg gives two to five hours in one place and two to six in another. Access, electrical work and pipe routes can add time, and a multi-head job or a long pipe run can take a full day (Aircon Master).
Is a bigger aircon always better?
No. Ask how the size was worked out. Room size is part of it, but sun, glass and ceiling height count too. A size picked off the shelf, with nobody looking at the room, is the quote to question.
Will an inverter aircon work during load-shedding?
An inverter aircon does not run through a power cut by itself. It needs a compatible backup supply. Check the unit's starting and running demand, other connected loads, battery capability and expected runtime with the person assessing the backup system. The inverter aircon guide goes through it.
How often should an aircon be serviced?
Once a year, ideally before summer, is the figure ServiceLink SA gives for a home aircon used in the hot months. It suggests every six months for heavy use or a dusty spot. Your unit's manual gives the maker's interval. Clean a user-removable filter only as the manual directs, after safely disconnecting power. The coils and the drain are a technician's job. See aircon service and maintenance.
Can I put an outdoor unit up in a complex or estate?
Check your body corporate or estate rules before an outdoor unit goes up. Ask the managing agent or trustees what they need to see first, and mention it when you request a quote.
Who is allowed to do the refrigerant and electrical work?
Work on the refrigerant circuit needs an SAQCC Gas registered practitioner. A new electrical circuit needs a Certificate of Compliance from a registered electrician. Ask who will do each part before you say yes to a quote.
