Is Servicing our Air con a must?

Why do we need to service our Air conditioner?

We all use machines all the time. It may be our cars or our washing machine or even an air-conditioner. We expect them to work for a long time, but the mistake we commit is, we don’t maintain it properly. Just like a human body, machines need regular checkups to see if all the parts are functioning. A well taken care of machine can in fact work longer than what it’s supposed to work for. With a couple of changes to some small parts you are looking at using a product for almost a decade.

Air conditioner is our saviour. It’s what keeps us cool and keeps us away from the heat. In humid conditions like Singapore, its what keeps us dry and cool. If the air conditioner on the office malfunction, I am sure the company staffs will make hell lots of noise. So let’s talk a bit about the air conditioner and how you can keep it running for a long time.

How does an air-conditioner work?

An air conditioner contains a liquid that evaporates, when liquid at a very low temperature evaporates it releases cold air. This cold gas moves through a coil and a fan blows against this coil that makes your room cool. To turn the gas back to a liquid, a compressor is used. The compressor gets hot because of this process; hence there is an external fan that is outside your house that blows the hot air out.

The condenser and evaporator are two other important parts of an air conditioner. The condenser is where the gas is liquefied and cooled down. A fan passes air through the evaporator, which is now cooled, that send the cool air.

Why do you need to service an air conditioner?

As you can see the air conditioner goes through a lot of pressure and different temperatures. This constant change has an impact and in turn there is a lot of wear and tear on the parts. There are filters that protect from particles in the air, there are coils that go through varying temperatures, and there are fans that blow clear air. All this needs to be checked and serviced every once in a while to have an efficient cooling system.

What are some common problems and how can it be fixed?

1. There is a filter in every air conditioner that takes in the hot air through netting to collect all the particles. If this isn’t there, the impure air will go in and spoilt the coils and release harmful air when cooling. Most modern day filters can be removed and cleaned; they can even be washed with water. This makes your Air conditioner more efficient because air goes in faster without any impurities restricting its movement. 

2. Every once in a while the coils need to be checked and any dirt from it need to be removed. The coils have a lot of air flowing through it and sometimes it may have air that is full of dust. If this goes unchecked, then the air conditioner could stop working. 

3. Most air conditioners also have thermostats that control the temperature of the room by measuring the levels of humidity and heat and so on. If the thermostat is sensing that the rooms needs more cooling, then it will work in over-drive. To make sure the air conditioner is working in a consistent environment, make sure all leaks in the room are plugged. Any cool air going out of the room will only make the air conditioner work more. 

4. The compressor and condenser are generally outside the house; try to keep them away from direct sunlight because they are trying to emit heat out and if kept under direct sunlight then the efficiency goes down. The external equipment of the air conditioner should be kept in preferably an open space and not among plants and shrubs that just slows the process of heat emission.

This is what we do to keep our air conditioner working properly.
