What commissioning covers on site
Commissioning is more than switching the unit on and walking away. We check that the installation matches the manufacturer’s operating limits, the pipework is sound, the drain runs freely and the indoor and outdoor units are communicating correctly. For homes, shops, offices and light industrial spaces in Mbombela, White River, Hazyview, Klerksdorp, Potchefstroom and Rustenburg, the goal is simple: steady cooling, proper airflow and no avoidable call-backs.
Our technicians confirm the setpoint, fan speeds, mode selection and timer functions, then watch the system through a full start-up cycle. If the unit has been off for transport or installation work, we allow for stabilising time and then verify performance under normal load. On inverter systems, we check ramp-up and running behaviour so the unit does not short cycle or waste power during load-shedding recovery. Small things matter here, like a drain trap that is slightly off level or a loose flare nut that can become a bigger problem later.
- Operational test of cooling and fan functions
- Drainage check for correct condensate flow
- Remote or wall controller setup and basic user settings
- Temperature response and air delivery check
- Visual inspection for vibration, noise or leaks
Our commissioning process from first switch-on to handover
We follow a clear process so the unit is not just running, but running correctly. First, we inspect the installation against the site layout and confirm the electrical supply, isolator position and breaker rating. Then we check the indoor and outdoor locations, clearances and access for future servicing. Once power is applied, the unit is started under controlled conditions and tested for normal response. If the system includes multiple indoor heads or a cassette, each zone is verified one by one.
After the technical checks, we explain the settings to the person on site. That includes how to select the right mode, what temperature range is sensible for the space, and how to avoid unnecessary strain on the unit. We also point out maintenance items such as filter cleaning and keeping the outdoor condenser free of leaves, dust and packing materials. For coastal humidity, Highveld dust and Lowveld heat, this guidance is not optional, it keeps the system efficient. Clients often ask us to commission replacement units too, especially where older systems were removed after repeated faults.
- Pre-start inspection and electrical confirmation
- Initial run and operating pressure or performance check
- Airflow, noise and condensate review
- Controller setup and user handover
- Commissioning note or service record where required
Turnaround times for homes, shops and commercial sites
For a single wall split or portable unit, commissioning is often completed during the installation visit once the system is ready. Where there are several cassettes, long pipe runs or a site with after-hours access only, we book enough time to do it properly and not rush the final checks. In Mbombela and nearby areas, same-day commissioning is often possible if the install is straightforward and the stock is on hand. In Klerksdorp, Potchefstroom and Rustenburg, timing depends on access, travel and whether the site is new build or an existing premises.
We also plan around municipal by-laws, body corporate rules and shop trading hours where noise or access is limited. If a building needs testing before tenants move in, we can align commissioning with the handover date so the aircon is not left half-set. For businesses that close late, we can schedule an early morning or after-hours start-up. This helps avoid disruption and gives us a cleaner reading of how the system performs when people are actually in the space.
- Single split unit: usually same visit if installation is complete
- Multi-split or cassette site: allow extra time for zone-by-zone checks
- Commercial premises: booked by arrangement, often after hours
- Replacement units: timing depends on removal and re-fit work
Pricing approach and what affects the cost
Commissioning is priced according to the system type, the number of indoor units and the amount of testing required. A small wall split in a residence will not take the same time as a ceiling cassette in a restaurant or an office block with several zones. We quote fairly and keep the price tied to the work that must be done, not a vague call-out figure. If the unit was supplied and installed by us, commissioning is usually built into the job scope. If we are asked to commission equipment that was installed by someone else, we first confirm that the installation is safe and suitable before proceeding.
Extra time may be needed where pipework is long, drainage is hard to reach, or the site has special access conditions. Faults found during commissioning are discussed before any extra work is done. That way you know whether the issue is a setting, a wiring problem, a drain issue or a refrigerant concern. In our experience, a proper final check saves money because it catches small errors before they become warranty disputes or repeat visits.
Settings we confirm before we hand over
The right settings depend on the room size, heat load and how the space is used. A retail shop in Rustenburg, a home in White River and a boardroom in Potchefstroom do not all need the same approach. We check the set temperature, swing function, timer options, sleep mode where applicable and the fan speed profile. On inverter systems, we also look at how the unit settles after the target temperature is reached, because that affects comfort and running cost.
We keep the handover practical and short. The aim is for the client to understand what the system can do and what it should not be asked to do. For example, setting a unit too low in extreme Lowveld heat can cause unnecessary strain, while running a portable unit with the hose badly routed can undo much of the cooling effect. A quick explanation at the end prevents those mistakes.
- Temperature and mode settings matched to the space
- Timer, swing and fan controls explained
- Inverter behaviour checked for stable operation
- Portable unit hose and vent position confirmed
Service intervals after commissioning
Commissioning is the start of the service cycle, not the end of it. For homes, we usually recommend scheduled servicing once or twice a year depending on dust, pets and how often the aircon runs. In the Lowveld, where systems work harder for longer periods, twice-yearly attention is sensible. In dusty North West conditions, filters and indoor coils can clog faster than people expect. Offices, clinics, shops and restaurants may need a tighter maintenance plan if the units run most days.
A good interval helps keep airflow strong, drain pans clean and refrigerant performance within range. It also reduces the chance of nuisance trips when the power comes back after load-shedding. If your site has cassettes in a ceiling void, we recommend regular checks on the condensate line and access panels too. For replacement units, the first service after commissioning is a useful time to confirm that the installation has settled properly and no fittings have worked loose.
- Homes: every 6 to 12 months depending on use
- Commercial spaces: every 4 to 6 months where operation is daily
- Dusty or high-humidity sites: more frequent filter and drain checks
- After major power interruptions: a quick operational check is wise
Why clients call us for final testing
Clients use us for commissioning because the last 10 per cent of the job matters. A unit can be mounted neatly and still perform poorly if the settings are wrong or the drain is not flowing. We work across Mbombela, the Lowveld and North West with stock knowledge, installation experience and local site conditions in mind. That includes hot afternoons, power cuts, long cable runs and buildings where access is tight. Our team knows how to get the system ready for proper day-to-day use, not just a quick demo.
When the job is complete, you should know what the aircon is doing, why it is set that way and when it should be serviced next. That is what a proper handover gives you. If there is a small issue, we sort it while we are still on site, which is better for everyone.
