Domain's Inverter reverse cycle air conditioning is perfect for can heating and cooling your home. It can be one of the most efficient ways to heat your home using electricity.

Domain's reverse cycle air conditioners absorb heat from the outside air to warm the air inside. This is a more efficient heating technique than other conventional heating appliances which have to "create" heat energy.

Domain's air conditioner absorbs the heat from the inside air and dissipates it the outside, leaving your home comfortable and cooler.


Domain's inverter split system air conditioners are more powerful whilst also more energy efficient than conventional systems. The inverter technology works by automatically varying their speed up and down in relation to fluctuations in room temperature to provide a more consistent desired temperature.

This ability to vary the speed of the compressor allows Domain's inverter systems to be highly energy efficient. These premium inverter split system air conditioners offer various operating functions including heating, cooling, fan, dehumidification(dry) mode, and multiple fan speeds ensuring your comfort all through all seasons for many years to come.


The compressor is the heart of a Domain air conditioner. Situated within the outdoor unit, the compressor pumps refrigerant to the indoor unit. This unit features a quality rotary compressor.
