A split system air conditioner is the type you can easily find in Singapore. It is the typical system to cool a room for apartment dwellers or homeowners. As its name suggests, the system is comprised of two units—an indoor unit and an outdoor unit.


The indoor unit is commonly installed on the interior walls of your home. At the same time, the outdoor one is placed outside, and they have refrigerant tubing connected to both units.

In Singapore, a central or ducted air conditioner is the common choice for indoor cooling of buildings, such as offices, shopping malls, and other multi-storey buildings. It requires extensive ductworks because it regulates the air through ducts in the building.


In the central system, the outdoor unit can comprise an evaporator, condenser, and compressor in a single unit. It cools an indoor space by pulling out the warm air to the outdoor area, pushing chilly air through the installed ducts, and coming out from a ceiling-mounted unit.


Therefore, in Singapore, it is also known as a ceiling-mounted aircon.



  • The best in terms of regulated cooling and humidity if compared to split-systems
  • Ductworks making it possible to cool an entire house or indoor space
  • Quiet and noiseless in the indoor space
  • No distracting bulky indoor unit to mess up your interior design

  • Rarely a suitable option for homes in Singapore
  • Duct problems mean a higher electricity bill and a decrease in efficiency

You need to know how much you are willing to pay for a new aircon.

Energy rating


In simple words, energy rating helps to determine how energy efficient an aircon is. The more efficient an aircon is, the better it will be for your electricity bill. Hence, when deciding which aircon you want to buy, you need to consider the energy rating.


Pick an aircon with a high energy rating if your budget allows it. The higher the rating, the more efficient the aircon is.


BTU or cooling capacity


British Thermal Unit (BTU) refers to the cooling power of an aircon. A greater number means greater cooling power. However, just because you can buy an aircon with high BTU does not mean you should.


We suggest that you consult seasoned technicians to determine the best BTU for your aircon.
