Our suppliers

Dahlsens supplies split system and ducted products from the best HVAC brands in Australia including Fujitsu, Haier, Daiken, Samsung, Rinnai and Brivis.

HVAC range

Through Dahlsens, builders can access installed split systems and multi-split systems, ducted air-conditioning, evaporative cooling and ducted gas, supplied and installed across Melbourne, regional Victoria, Sydney, Gosford, Newcastle and Wollongong.

Single split systems

For customers seeking fast and efficient temperature control in one room, a single split system is an effective HVAC solution. Single split systems are available in both air conditioning only and reverse cycle options. With low installation and running costs, a single split system is also an economic choice for budget conscious clients.

Dahlsens can provide access to a wide range of quality products in various sizes and designs. No matter your clients style, we have a single split system unit to suit their needs

Multi split systems

Multi split systems combine the simplicity of a wall mounted HVAC unit with the convenience of heating or cooling multiple locations. Ideal for residential homes with limited ducting capacity, multi split systems can run up to five split system units from just one outdoor unit. All locations can be controlled individually and customised with many unit sizes and designs.

Ducted systems

A ducted heating and cooling system gives your customers the ability to control the temperature throughout their home at the touch of a button. Fully customisable zoning solutions allow your clients to reduce running costs by limiting climate control to the rooms they use most.

Ideal for clients who value aesthetically pleasing climate control solutions, ducted systems are discreet and quiet. Ducted systems are available in a variety of options to suit residential or commercial builds. For customers in smaller homes with limited ducting space, Dahlsens can even supply slim line ducted systems which require less space to install.
