Hi there! Based on your question about Defy outdoor air-conditioning units, I found a few relevant options from my PriceCheck search results: The De-installation of a 9000-24000 BTU Defy wall split unit for R750 would allow you to upgrade your current system. The Professional Installation of the same size unit for R2700 includes the copper piping kit and guarantees proper installation. I also saw the Defy Portable Aircon 12000BTU Condenser Fan Blade available for only R428.95 in case you need a temporary solution or extra cooling for a single room. Let me know if you need any other details on these Defy air conditioning products! I'm afraid I don't have the full catalogue available, but I'd be happy to search again or provide any other recommendations that could help.
