What Size Ducted Air Conditioner Do I Need?  

Having the correct sized ducted air conditioning system installed in your home will ensure that your home is properly heated and cooled to your desired temperature.  

Most ducted air conditioning systems have a lifespan of around 10-20 years and once they are installed, it is difficult and expensive to change, so it is important that you get the right one installed the first time.  

If you make the mistake of choosing an undersized system for your home, you will find that it needs to work extremely hard to reach the ideal temperature. When an air conditioning unit is working overtime, it is loud and not energy efficient which can cause your energy bill to skyrocket.  

In addition, the stress that you put on an undersized unit will lead it to break down faster which can cause you to spend hundreds to thousands in repairs over its lifetime.  

The other side of the coin is choosing an air conditioning system that is too large which has its own set of problems including excess energy consumption that can take a major toll on your energy bill.  

So that brings us to the sometimes complex question of what size ducted air conditioner do I need? This article will help by giving you some insight into how to determine what size unit will be most efficient for your space.   

What Size Air Conditioner Do I Need for My House?  

If you are thinking of investing in a ducted air conditioning system for your home, you are likely asking yourself this question. We will break down how to determine what size air conditioner you need for maximum efficiency.  

The best way to determine what size air conditioner you need is to use a BTU calculation. BTU, or British Thermal Unit, is an energy unit. It is approximately the energy that is needed to heat one pound of water by 1 degree Fahrenheit.  

BTU calculation can be used to help you determine what size air con you need for your home. BTU can be used as a point of reference for the amount of heat that your air conditioner can remove from the surrounding air.  

The air conditioning unit size that you choose for your home will depend on the size of your home. A smaller home with shorter lengths and widths will require fewer BTUs to cool and a larger home will require more.  

However, it is important to keep in mind that the volume of your home is a more accurate measure because ceiling height is factored into the equation as well.  

Every three-dimensional cubic square foot of space in your home will require a certain amount of BTU usage to cool it properly. The smaller the volume of your home, the less BTUs you will need.  

The BTU calculation formula for air conditioner size can easily be calculated using the measurements of your home and ceiling height.
