An aircon service in Johannesburg is a scheduled clean and check on a unit that is still working: filters, coils, drain, electrical connections and a performance test. It is not a repair, and it is not a maintenance contract.
Those three get quoted very differently, so it is worth being clear about which one you want.
| What it is | When you want it | |
|---|---|---|
| Service | A once-off clean and check on a working unit | Start of summer, or once or twice a year |
| Repair | Diagnosing and fixing something that has failed | The unit is not working properly |
| Maintenance | A standing schedule of services under contract | Multiple units, or a business that cannot afford downtime |

Get Service QuotesWhat Is Included in an Aircon Service?
- Filters removed, washed and refitted.
- Indoor evaporator coil cleaned and the blower wheel checked.
- Condensate tray and drain line cleared and flow tested.
- Outdoor condenser coil cleaned and the fan checked for noise and play.
- Electrical inspection: terminals, contactor, capacitor reading, isolator.
- Operating pressures and temperature split checked against expected values.
- Remote, controls, thermostat and mode operation tested.
- Casing, brackets, pipe insulation and drain fall checked.
Get the scope in writing. "Service" is used for anything from a ten-minute filter rinse to a full strip and chemical clean. The wide spread in service prices is almost entirely scope, not rates.
Does a Service Include a Regas?
No, and it should not. Refrigerant is checked, not topped up as routine. A correctly sealed system holds its charge for its working life. If pressures read low, that is a leak to find, and it is quoted separately.
How Often Should an Aircon Be Serviced?
| Use | Suggested frequency | Why |
|---|---|---|
| Domestic, seasonal use | Once a year, before summer | Filters and drains do the damage, both are cheap to stay on top of |
| Domestic, running most days | Twice a year | Coil fouling accumulates faster than people expect |
| Office and retail | Two to four times a year | Longer hours, more occupants, dust from foot traffic |
| Restaurant and kitchen-adjacent | Quarterly | Airborne grease loads the coil and the blower wheel |
| Dusty and industrial areas | More often on the outdoor unit | Highveld dust and particulate blanket the condenser coil |
| Server rooms and continuous duty | Quarterly, under contract | The unit never stops, and a failure has consequences |
Filters are the exception: those are a monthly job in summer and you can do them yourself in five minutes.

Indicative Johannesburg ranges, not a quotation. Scope is what moves these. A basic service and a full chemical clean are different jobs; compare quotes on the task list, not the headline price.

Compare Service PricesResidential and Commercial Servicing
Domestic servicing is priced per unit per visit and booked when it suits you. Commercial servicing is usually priced per unit across a site, often outside trading hours, and frequently with a written report per unit for the building file. If the site has more than about six units, ask for the maintenance contract price as well — it is commonly cheaper per visit than booking each one.
Frequently Asked Questions
How much does an aircon service cost in Johannesburg?
A standard single split unit service is commonly R650 to R1,400. A full chemical deep clean runs higher, generally R1,200 to R2,800 per indoor unit, because the unit is stripped rather than wiped.
How often should I service my aircon?
Once a year before summer suits a domestic unit used seasonally, and twice a year suits one that runs most days. Commercial and kitchen-adjacent units want more. Filters are separate and want cleaning monthly in summer.
Does an aircon service include gas?
No. The charge is checked, not routinely topped up. A sealed system that is genuinely low on refrigerant has a leak, and finding it is a separate job from servicing.
What is the difference between a service and a deep clean?
A service cleans the filters, the accessible coil faces, the drain and checks the electrics. A chemical deep clean strips the indoor unit, including the blower wheel and the full coil, and is what actually clears mould smells.
Will a service make my aircon colder?
Often, yes. A fouled filter and coil restrict airflow, which shows up as weak cooling and a higher bill. If cleaning does not restore performance, the next question is the refrigerant charge or the compressor.
