  • Evaporative Cooling – This is the cheapest option without compromising on cooling efficiency. Running costs are also low so you can have control over energy bills while enjoying a comfortable environment.
  • Add – On Cooling –This unit is basically used to heat rooms through a gas deducted heater but some minor modifications of the components and additionof refrigerant, have transformedit into a cooling system. This saves you money by eliminating the need to install separate heating and a cooling units.
  • Wall Split Systems – If you need a heating and cooling system specifically for one room, opt for a Wall Split System. These units quickly cool the entire area where it is placed and are low fuss.
  • Ducted Split Systems – These systems work on much the same principle as wall split systems, but they heat and cool the whole house via a ducts. They require a slightly higher investment to install, but are extremely high value, offering top of the line quality, convenience and energy efficiency.

  • Wall split systems – A very versatile unit, it can be used in the summer as an air conditioner and heater in the winter. It is best suited for single rooms such as bedroom, a study or living room.
