Add On Air Conditioning Systems
An add on system works with your existing or new gas ducted heating to provide your home with a refrigerated air conditioning solution. The system is comprised of an outdoor and an indoor unit and works by pushing cool refrigerated air through the same ducting into your home as your gas heating. Depending on your current heating unit you may be able to ‘add on’ the Add On air conditioning system or have a new heating unit installed and add on the air conditioning system later on. The Add On system can also be zoned which will help maximise energy efficiency and cut down on your power bills.
Our team of expert technicians ensures seamless integration of add-on systems with your existing HVAC infrastructure. With meticulous installation and professional craftsmanship, we ensure that your add-on units function seamlessly with your current system, maximizing performance and reliability.

Excellent job done. The customer service is second to none. We had a couple of technical issues but Rory and his crew sorted all of it out quickly.
