Before Buying an Air Conditioner

What are the objectives of the Energy Labelling Scheme?

The objectives are: Providing consumers with energy efficiency information of labelling product to make purchase decision. Differentiating the product by energy efficiency and simulate introduction of cost effective, energy efficient technology. Enhancing effort to promote environmental protection initiatives through usage of energy efficient product. For more information, please visit Singapore National Environment Agency (NEA) website at this link.

What does the Green Tick Rating Label means for air conditioning?
The Green Tick Rating Label means how energy efficient the air conditioner is according to the number of ticks given.
What is the estimated electrical consumption of an air conditioner per month?
It depends on the air conditioner model you are using and the usage pattern. The estimated electrical consumption can be calculated by using the following formula: Estimated Electrical Consumption = Input (kW) X No. of hours used X No. of days per month X Current Utility Rate
What is the average life span of a residential air conditioner?
Generally, the average life span of any air conditioner is six to seven years. This is subjected to usage pattern and regular servicing of the air conditioner by a qualified air conditioner technician.
What is an Inverter air conditioner? Is this more efficient than a non-Inverter conventional air conditioner?
An Inverter air conditioner delivers cool air by varying the frequency of the compressor, and thus regulates the refrigerant to satisfy room cooling requirements and achieve the desired temperature with minimal fluctuations. It eliminates waste with precise control. In this way, it is more energy efficient.
What is the average price of a Daikin air conditioner unit?

It depends on the air conditioning system requirements. Please contact our Authorised Dealers for more details.

What model is suitable for my residence?

Steam Cleaning

What is the difference between steam cleaning and chemical wash?

Steam cleaning is an eco-friendly way to clean choked and smelly fan coil unit.

Steam is used to clean the evaporator coil whereas for chemical wash, alkaline solution is used.

How often should my aircon conditioner be serviced by steam cleaning?

Steam cleaning does not affect the coil condition. It will not cause corrosion on the coil. 

Steam cleaning can be recommended as and when the coil is choked and smelly and this depends on the usage pattern of the aircon units.   

There are some feedbacks that steam cleaning is not effective in cleaning badly choked coil. Why is Daikin recommending steam cleaning now?

Normal steam cleaning will only clean the evaporator coil surface. The steam does not penetrate into the coil.

Daikin unique steam cleaning is able to provide high steam penetration into the coil to effective clean the choke coil.

In what industries / condition is steam cleaning recommended?

Steam cleaning is highly recommended in industries dealing with food as no chemical is used.

Other industries that will benefit from steam cleaning are restaurants, childcare centre, hospital and clinic.
