What Size Ducted Air Conditioner Do I Need? - 039 edited

To get relief from the scorching heat of the summers, buying a ducted air conditioner would be a great idea. But while purchasing an air conditioner, selection of appropriate size would be the major factor to strike your mind. Investing in a right-sized air conditioner and placing at an ideal location will give you almost 100% efficient performance. Additionally, this will also contribute to its longevity.

Why size matters?

If you purchase an incorrect sized ducted air conditioner or install it at a wrong place, it would tend you to bear loss in terms of efficiency, energy consumption and electricity bills. For instance, buying a small capacity AC for comparably large space would not cool the area much. As a result in athe10-20 year life span, your AC needs would need repairing around 20-50 times.

The problem with the larger one is energy consumption, which can compel you to pay a huge amount of bill. Hence, choosing the right sized air conditioner can heat and cool your room to your desired temperature in an efficient way.

The importance of position

At times, the position of AC in your room could also affect its efficiency. For example, fixing it beside the window, from where maximum sunlight comes will take more time to cool your home. This would in turn tend you to pay more bills while receiving less cooling.

If it is a larger house then the BTU rate will be larger. However, calculating the volume of the rooms can give efficient results, as it will include the volume of the concerned room.

Making calculations according to the Thumb rule would also help you significantly to determine the size of the ducted air conditioner with respect to the space. In this method, you need to calculate the total daytime living floor area and multiply with the watt of energy required per square meter.
