We install only the best nationally and internationally reputed brands. This gives you peace of mind and ensures years of trouble free service.

We offer quality systems including:

  • Ducted Heating Systems: How it works – Internal air is drawn out and passed over a heat exchanger. The warm air is then pumped back into the room.
  • Wall split system: How it works – This is a versatile unit and can be used in summertime for cooling. There is an outdoor unit and an indoor one and is generally meant to treat temperatures of a fixed room and space. It is ideal where temperature of one room has to be controlled and the unit is installed there.
  • Ducted Split system: How it works – This is similar to wall split system with one major difference, the indoor unit is concealed and warm air is pumped through hidden ducts. The air is released into the room through specific openings at the end of the ducts. This system is comparatively more costly than the other two systems but makes up for the initial investment by being very efficient to run.



We offer a wide range of air conditioning units designed to meet your specific requirements and budget.

  • 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.
