A Complete Guide For Buying, Using And Maintaining Your Aircon System

The hot and humid weather of Singapore is usually either hated or loved by Singaporeans. Some love it for the fun, warm sunshine and summer while the others see it as a place of sweat and discomfort.

In the climate of Singapore, the requirement of an aircon system to bear the scorching heat of summers is a constant for all. As soon as the summer approaches in Singapore, we all start to clean, upgrade and sometimes install new aircon units to maintain the comfort of our homes and work spaces.

It is also the time when many of us realize face the need to replace or get an additional aircon. Times like these help us realize how difficult choosing an efficient aircon system can be.

If you lack technical know-how and are in the need of getting a new aircon system, then have a look at the following points.

Selecting The Right Aircon System To Buy

When you enter the market, you will find a lot of model and brands of aircon, such as Daikin or Mitsubishi, and each of them are equipped with attractive features.

However, before buying any of them, you have to ensure that the aircon is efficient enough to provide proper cooling for your home. In addition to that, budget will be another important influencer of your buying decision.

While you factor in your budget and requirement, allow us to guide you through the technical aspects so that you can reach a wise decision.

Enlisted below are different parameters that you must check before going for an aircon installation.

Consider The Cooling Area And Its Heat Sources

Air-conditioning systems comes in different cooling capacities, and you have to decide the ones that can work in your place.

If your aircon’s cooling capacity is lower than required, the cooling system will have to run for an extended period to maintain the temperature, and you will end up with high electricity bills. The other side effect is that the the area will not be cold.

On the other hand, if you go for an aircon with more than required capacity, you will have to invest more.

Therefore, check the area of your place and the heat sources around it before selecting any aircon.

One way of calculating the required capacity is to divide the area of your site by 600 and then add 0.5 to it for every person living in that place. If the room temperature of your location goes beyond 45 degrees during summer, you can add 0.5 for that too. This calculation will give you an approximate value of required aircon in tons (the unit of aircon capacity).

Another method is by calculating the aircon BTU of the unit before installation. More on that in a while.

Choose The Type That Fits Your Space

Depending upon the capacity requirement and the space of your place you have various types of aircon system that you can buy. Have a look at some common types:

Window Aircon System

They are the simplest and easiest to install aircon units. Usually, they look like rectangular boxes and have all the components packed in a single housing. To install it, we just place it on the window and fix it there. There are no ducts or any outdoor units. However, they are noisy and slightly low in efficiency.

Duct Less Aircon System

The ductless aircon system is a set of two units which work together provide cooling that you need. One of its housing sits outside your place and work to cool down the refrigerant while the other sits inside your house, delivering cold air blows.

For installation, we will need a solid base for the outdoor unit, some room for coolant tubes and a holder for the indoor unit.

Packaged Aircon System

When you need cooling for more than one room with a single cooling system, packaged aircon are a great option. This single-unit aircon has an inlet and outlet of ducts that it uses to transfer cold air to your place. We usually recommend this aircon system for small offices, halls, and apartments.

Central Cooling Unit

We prefer central cooling units for clients who need temperature control for the whole building or house throughout the year. This system consists of a large compressor that generates air blow, and networks of ducts to distribute the air.

The best thing about this aircon system is that it’s adjustable for winters too. We can set it to blow hot air during the winters.

Portable Aircon

Portable air-conditioners are compact devices which need no complicated installation or stationary fixing to work. It has a flexible pipe which goes out through a window or other opening. The aircon will use this pipe to circulate the air and provide cooling. There are no fixing or mounting requirements.

The only downsides are its limited capacity and noisy operation.  

Installing the Aircon System

Aircon installation is not that complex, but it needs precision, experience, and skills. Even a slight mistake in this part will have drastic effects on its working efficiency, life and can increase damage occurrence.

We also have to adopt different techniques and have to use many advanced tools. Like for window aircon, we have a frame and holding unit, whereas for a central aircon we need vents and ducts. We also have to consider a lot of other factors like location, airflow, the drainage system, and more, before placing the aircon anywhere.

As for the price of installing, it will depend on many different factors like:

Types of Aircon System

We have to drill hole, connect tubes, braze them and set more than one unit for a split aircon system. For ducted aircon system like the packed or central aircon, we have to set a complex network of metal ducts for air circulation. While the window aircons need just a frame and some fasteners.

Therefore, we cannot set a standard price for aircon installation. It will depend upon the requirements of your aircon and several other factors.

Working Requirement

Installation of aircon sometimes needs installation of new vents and wiring too. Both of these extra work needs time and skills which means they will add to the installation cost. 

Number Of Units

The more units you have, the more will be the effort which we have to put. There will be an increase in brazing work, fixing and a lot of other tasks. Therefore, with every aircon unit, the installation cost will also increase.

One important metric to take into account is your aircon BTU. It is a measure of your air-conditioning units cooling power and can determine how many units you need for a room. You can read more about aircon BTU and its calculation here.

Complexity Of The System

If you need simple duct works and installation, it won’t need much expertise, but if you need a complex setup, it will need more specific knowledge. It will have a direct effect on the overall costing of the aircon installation.


In case of a split aircon system, more distance will mean more tubing work. The aircon may also need a gas top-up to compensate for the extra length. Therefore, the installation price will increase with the increasing distance of your indoor and outdoor unit.

Taking Care Of The Aircon System

The aircon systems are very efficient in their working, but different factors influence it. We can help you to deal with some of them like filter replacement, repairing aircon broken parts, clogging and more.

Still, there are practices you can consider for better working of your aircon system:

  • Avoid leaving the aircon system switched on while you are not present; this will give the system some time to rest and increase its lifespan.
  • A filthy aircon is prone to many problems like decreased efficiency, strained motors, overloading and more. Therefore, try to keep it clean and serviced.
  • Try to avoid heat-generating appliances while the aircon is running.
  • Direct sunlight on both indoor and outdoor unit affect their efficiency, so try to shade them from direct sunlight.
  • Even a small decrement in refrigerant can influence the aircon system. It is best if you keep an eye for the low refrigerant symptoms and call us for aircon gas top up when you notice them.
