Installing an air conditioner involves electrical work and handling refrigerant gas, and both are regulated. Here is what to check before work starts.
Electrical work and the CoC
New electrical circuits and changes to your installation must be done by a registered electrician, who issues an electrical Certificate of Compliance (CoC). Larger aircons often need their own circuit and breaker. Keep the CoC with your house documents — you will need a valid one when you sell the property.
Refrigerant handling
Refrigerant work — connecting, pressure-testing, vacuuming and charging the system — should be done by a technician registered with SAQCC Gas, the body that registers gas and refrigeration practitioners in South Africa. Ask to see the installer’s registration card.
Body corporate, HOA and neighbours
In complexes and estates, get written approval before installing, and ask whether there are rules about outdoor unit positions, colours or trunking. Place the outdoor unit where its noise and warm air won’t bother neighbours.
Paperwork to keep
- Your invoice for the units.
- The installer’s invoice or installation certificate, with the date and model numbers.
- The electrical CoC, if electrical work was done.
Do I need a CoC for an aircon installation?
If new electrical work is done — for example a new circuit, plug or isolator — the registered electrician who does it issues a CoC for that work. Ask your installer whether the job includes electrical work and who will certify it.
What is SAQCC Gas registration?
SAQCC Gas registers practitioners who work with gas, including air-conditioning and refrigeration technicians. Using a registered technician means the refrigerant is handled safely and legally.
