Small Duct Air Conditioning Systems

South Australia’s Small Duct System Specialists


Carman Heating is a leading supplier of the newest technology - small duct heating and air conditioning. A Small Duct System (SDS) can deliver high performance heating and cooling comfort all year round - without the limitations of the more traditional heating and cooling systems. What’s more Small Duct Systems have been tried and tested around the world for the past 40 years and built a strong reputation for high performance and reliability.

Small Duct Systems are unique due to the compact size of their ducts which start from as little as 50mm (as opposed to a more conventional system where ducts can be as wide as 500mm). This means the temperature inside of the duct of your SDS is less likely to fluctuate, giving you a constant heating or cooling temperature every time.

Designed for Installation

Designed for Installation into Tight Spaces


Small duct air-conditioning is perfect for tight spaces and makes installation issues and budget blow outs a thing of the past. Your Small Duct System can fit where others can’t which means no change to building plans or having to compromise the architectural integrity of your Adelaide home, apartment, building or development.

No bulkheads or other space reducing measures necessary as Carman Heating can install Small Duct Systems throughout South Australia to fit any space - in ceilings, under staircases, even down stud walls. Small Duct Systems offer heating and cooling options in a compact size, which means they can be successfully installed into places where the more conventional ducts don’t fit. SDS is also ideal for the popular Adelaide flat roof home where space is often limited.

SDS for Complete Zone Control

SDS for Complete Zone Control


Small Duct Systems are extremely energy efficient using high performance fans that can reduce running costs by up to 50%. Another reason why people love Small Duct Systems is that they can be separated into individual zones. This means you can control one or all of your zones from your thermostat to maximise the efficiency and operation of your Small Duct System and can even integrate it into your home automation system.
