“Air conditioning was a most important invention for us, perhaps one of the signal inventions of history. It changed the nature of civilization by making development possible in the tropics. Without air conditioning you can work only in the cool early-morning hours or at dusk. The first thing I did upon becoming prime minister was to install air conditioners in buildings where the civil service worked. This was key to public efficiency.”

  • Former Prime Minister Lee Kuan Yew 

There is no doubt in my mind whatsoever that the air con was vital to humanity. If not for the invention of the air con, I’d be a shrivelled up raisin with less moisture than my workout towel. 

One thing that people might not know about air cons is that they don’t just keep the air cool. Here are the 3 main features that they provide:


The top priority of any air con system is that it has to keep the indoor air cool and comfortable. Of course, the size of the space that is to be cooled will greatly affect what kind of air con system you get. There are central air units, window AC units, and ductless AC units for residential properties, while larger commercial buildings usually need special rooftop systems in place.


Air cons also help to dehumidify the indoor air – which is extra important in Singapore. In case you didn’t know, the humidity levels in Singapore range from 64% to 96%. According to this website, a comfortable level of humidity would be… 55% to 59%.

In an air-conditioned room, this number is maintained from 35% to 50%, which is very comfortable. This also happens to be the reason why most air con units have drains – as they dehumidify the air, the water has to go somewhere, and that somewhere happens to be the condenser. 

The drain helps to filter water away from the air con so that the water doesn’t just pool up and cause damage to the unit. 


Your air con also helps in ventilation – otherwise every room you step in would be stuffy and full of carbon dioxide. Most air cons have a fan mode in addition to their cool mode, which helps to move fresh air throughout your house/office. 

However, like all electronics, air con units are susceptible to wear and tear, and ultimately failure. So, how do we keep faulty air cons at bay? How can we make sure that they will behave as they’re supposed to, and fulfil their duties responsibly?

By hiring an air con servicing company, of course.

Here’s the rating criteria by which these companies will be judged:

  • Prices
  • Services provided
  • Customer reviews

As always, I have enlisted no services from any of these following companies, and thus have no prejudice nor preference towards any of them.

Google reviews from 372 people have put them at 4.8 stars, and it took about 3 pages of scrolling before I could find a review that wasn’t a full 5 stars. The only 1 star review I could find was by someone who misattributed a faulty water tray to the air con, aka it was their own fault.

Another 1 star review seemed to turn up a similar case, whereby a customer insisted a condenser was fine when it was in fact past its best-before date.

Five star reviews, on the other hand, are a dime a dozen, with many praising them for their reasonable prices and honest services.

Air Con-clusion

If you’ve read this far and developed a severe dislike for air cons, here’s an article on an alternate way to keep cool: a list of ceiling fans. With lights on them.

On the other hand, if you’re turning your back on the indoors altogether, would this be a good time for us to suggest a list of outdoor furniture?
