When choosing a central air conditioning unit, one must take many factors into consideration. Let us take a look at few of them.
Central air conditioners have set certain standards in the market today. Apart from keeping the air cool, these also filter and dehumidify it. When choosing a central air conditioner, there are many factors you need to consider like the budget and their requirements.
Before buying it, you have to first decide which parts of the office space or the home space, need air conditioning. Sometimes it so happens, that the entire building may need it.

Things To Consider While Choosing a Central Air Conditioner

1. Be sure about the size of the air conditioner. Because the right size needs to match the cooling power to the characteristics of your home. For this, you may need to ask your contractor to do a load calculation which would ensure that you can take a proper account of the size of the home, the window area, the insulation levels, and such other factors.
Apart from choosing the right size, one also needs to take care about the position of where the unit would be installed. This is because the position can also affect its efficiency. If there is too much interference in its vicinity, then there are chances the air won't flow freely through the area.
2. Look at the moisture performance. This is because your comfort depends as much on controlling the humidity, as it does on keeping the area cool. The conditioning systems vary in their ability to subtract the moisture from the air. Therefore, you need to ask the dealer about the performance of the units.
3. A large size system may sound very attractive and appealing but you must consider their drawbacks as well:
  • An oversized unit turns on and off very frequently as compared to one that is of the appropriate size.
  • They are comparatively costlier.
  • These also face more wear and tear.
  • Using an oversized system will not even run long enough to wring the moisture out of the air.
  • These systems also draw loads of electricity and subsequently give way to higher bills.
4. You might come across different seer ratings (Seasonal Energy Efficiency Ratio). This ratio gives you the necessary know how on the efficiency of the systems. Most of the new models do not have a rating that is below 13. The older units are known to have a seer rating of 7.


1. Central air conditioning systems are one of the most effective ways to regulate cool air throughout the building. The centralized units that cool the air also sends it through a direct route which is through the air ducts or the vents that are located in individual rooms.
2. Compared to the window air conditioning systems, these make less noise.
3. These have the compressor as the visible part of the unit, which is outside the building or in any such place that makes it as inconspicuous as possible. Therefore, they do not affect the view from your window or block the space. They do not take any added space in your room and are very convenient to operate.
4. They are also much more energy-efficient.
Most of the systems are known to work in a reversed cycle as well. This would simply mean that in winter, it pumps hot air. Besides, these also keep your entire house cool instead of cooling just one room.
