Weather is always so hot and humid here in
Singapore, and having a cold air-conditioned room to come home to, is one of
the best ways to escape the relentless heat. As you finally reached home, and
start to turn on the aircon, then suddenly you come to a terrible realization.
It is not as cold as before, even though you’ve bought it not long ago. It
could be that you didn’t really maintain your unit properly, giving it the
proper care that it deserves such as a chemical wash.
