With the hot weather that we are “blessed” with all year round, it’s little wonder why most of our homes need an air conditioner. But given the huge variety of options available in the market now, choosing a good air conditioner for yourself can get bombarding, especially if it is your first time getting one.
In general, there are 2 types of air conditioners available in the market —permanently built-in vs those that are portable.
As you might have guessed, portable ones are cheaper, more flexible and easier to install. However, they are limited in their air cooling capacity and also consume more floor space. Hence, if you’re intending to use the air conditioner for cooling a big room, you might want to avoid portable ones as they usually take a longer time to cool the place down.
But, if you’re looking for a short-term commitment to combat the sweltering heat, then portable air conditioners might just be the answer for you.
As the name suggests, built-in air conditioners are installed permanently either by the windows, at the top of a wall or through the ceiling.
Due to the special installation works involved, built-in air conditioners are usually more expensive than the portable ones. However, many residential homes still prefer these as they look not only sturdier and neater but also have a higher capacity to cool the place down much faster.
Among the various types of built-in air conditioners available, split air conditioning systems are the hot favourite for homeowners. These systems comprise of one or more indoor air con units that are mounted on the walls inside the house and are supported by an outdoor compressor unit.
To buy a good air conditioner, simply ask yourself these questions:
If the space that you want to cool down is a small room, portable air conditioners alone should work fine. Otherwise, you could go for split air conditioners, or even built-in central units to cool bigger spaces.
The next thing to consider is the number of rooms that need air conditioning. For most residential homes where more than one room need air conditioning, split air con systems are hugely popular, mainly because you only need one outdoor unit to support and separately control as many indoor units as you like.
If you’re tight on budget or just simply need a quick temporary fix, then go for portable air conditioners, which typically costs between $500 to $1,000. But, if you would rather spend on good quality and a longer lasting solution, built-in air conditioners like the split air con would work great. These air conditioners typically cost between $800 to $1,000 per system. i.e. if you need air conditioning in 3 bedrooms, you will need a System 3 air conditioner, which typically costs around $2,400 to $3,000.
Besides looking at the absolute cost of the air con, you should also consider:
And of course, when buying your air conditioners, do check out its specifications:
Aside from these basic specifications, also look out for other value-adding features that many air conditioners offer e.g. dust-proofing, cooling retention effects.
For all built-in air conditioners, you will need an air con specialist to have your air con installed for you.
Before getting your air con installer down, finalize exactly where you want to install your air conditioner in each room, based on:

During the air con installation process, walls will get drilled. And, there will be debris and chunks of wall cement falling onto the floor. So, ensure that your air con specialist has either laid floor protection covers or taken cautionary measures to protect the floors from the impact of the falling debris.
At the end of the air con installation, check that the walls are repaired nicely and that all the wires and pipes are concealed neatly.
