Increasing the efficiency of your air-cond

Increasing the efficiency of your air-cond can save you money in your electricity bills, as well as being good to the world environment too.

Here are the measures that I have taken to increase the efficiency of my air-cond:

1. Ensure the outdoor compressor unit blows the hot air away from your house

Some people made the mistake of hiding the compressor behind a pillar or wall. I almost made the same mistake too, if not my contractor reminded me that this will be bad for the dissipation of hot air blown out from the compressor. There should be no obstacle in front of the compressor unit.

Other than that, some people put the compressor unit close to a window, on a wall forming 90 degree with the window. Some other people just put it under the window (remember, hot air rises). This will make the hot air from the compressor blowing towards the window front. The hot air should be blown away from your house, and best located parallel and on top of your windows.

2. Place the indoor unit close to the outdoor compressor

This will not only save you cost in laying the air-cond hose, which normally charges per feet of installation. It will also make the refrigerant gas travels in shorter distance and faster to reach the indoor unit.

3. Confine the cool air from escaping the room

This is a common sense that most people awares. When using the air-cond, close up all the windows and doors to restrict cool air from escaping.

4. Tint the glass of those big sliding windows

There are tinting films available to install on the windows glass, blocking the heat, infrared and ultraviolet radiation of the sun from entering your house. This is particularly effective if the windows are facing west.

5. Switch on the ceiling fan together with the air-cond

This will tremendously increase the airflow, making the room cool down much more effectively, and in turn the air-cond unit need to work less harder.

6. Wash the air filter of indoor unit regularly

The air filter surface will fill up with dust over time. Take it out and wash it with tap water. Rinse it, dry it, and put it back. If the air filter is blocked by dust, your air-cond need to work much more harder.

The cleaning frequency depends on your usage. If you use the air-cond everyday, should clean the air-filter at least monthly. If you use it occasionally, then can clean it bi-monthly or at most quarterly.

7. Service the air-cond at least every 2-3 years

Servicing the air-cond includes disseminating its indoor and outdoor units, and clean with chemical. This will maintain its cooling efficiency.

8. Install turbine ventilators on your roof top

I seldom need to switch on the air-conds in my house eversince the turbine ventilator system is installed. The neccessity to switch on air-cond only come when the indoor temperature reaches above 30 degree Celcius, which is very rare.

And because the turbine ventilator system can effectively improve the air circulation in the house, it does help to make the air-cond works more efficiently the same way like the ceiling fan does, although the effect is certainly not as much as the ceiling fan.
