What is BTU?

A BTU (British Thermal Unit) is a rating used to determine the cooling capacity an Air Conditioner.

Typically a minimum of 7000 BTU is needed to cool a small room, whereas commercial units can reach up to 25,000 BTU and beyond. Simply, the greater the BTU, the larger the space that the unit can cool.

Tech stuff

The unit must be installed by a F-Gas qualified AC engineer. Please ensure the qualified fitter reads the user manual in full before installing.

These units contain a gas which is governed by F-Gas regulations. The gas must be handled by a qualified F-Gas personnel. Further information on the requirements and ensuring the engineer is qualified can be found at: Government Guidance

* Note: In order to reduce the Global Warming Potential, the outdoor unit footprint and provide extra energy savings; our outdoor units have a rating lower than the sum of indoor units BTU. Please note this will not affect the cooling or heating in individual rooms as those units are variable cooling inverters and they balance the cooling or heating power among the indoor units to achieve the target temperature in the shortest time. Please make sure you size the units as per our room guidance or call for tech support.
