What is a Certificate of Conformity (CoC) and do I need one?
Yes. In South Africa, any fixed aircon installation must be signed off by a registered practitioner. We provide a CoC with every installation, ensuring your homeowner’s insurance remains valid and your warranty is protected.
Which AC is best for load shedding?
We highly recommend Inverter units. Because they don’t have a massive “startup surge” of electricity, they are much easier to run on home battery and solar backup systems compared to older non-inverter models.
How do I choose the right size for my office?
Office spaces often have more electronics (PCs, printers) and more people than a home, which generates extra heat. We perform a heat-load calculation to ensure the unit we install can handle the “office hustle” without overworking.
Item #1How often should we service our office units?
Because office units often run for 8–10 hours a day, we recommend a bi-annual service (every 6 months) to keep filters clean and prevent unexpected downtime during the work week.
