How Do I Calculate What Size Air Conditioner I Need?

Air Cooling systems come in various sizes, whether they are central air cons or window air cons. Many people select an aircon that’s too big because they think it will be more effective but in fact, the opposite is true. It is less effective and it uses excessive energy.

Air conditioning units remove humidity and heat from the air. If the unit is too big, it will cool down the room fast but only remove some of the humidity. This will leave the room feeling moist and damp. If you opt for the correct size air conditioning unit for your home in Cape Town, it will remove the humidity efficiently while cooling your room.

Calculating the size

To calculate the size of air conditioning unit needed, multiply the width and length of the area to be cooled.

15 to 18 m² – 9 000 BTU
20 to 25 m² – 12 000 BTU
30 to 35 m² – 18 000 BTU
40 to 45 m² – 24 000 BTU
55 to 60 m² – 30 000 BTU

If you’re wondering if a smaller air conditioner will which size will work the best in your home, keep this in mind – Units with less BTU will have to run continually to try and cool your space. This will have a negative effect on your electricity bill and chances are your space won’t be cooled down effectively.

On the other hand, if you buy an air conditioning unit that’s too big, your space might cool down very quickly but there will be too much humidity left in the room, still making the environment uncomfortable.

It is crucial to calculate the correct air conditioner size if you want to adequately control the heat load of the air in your room. Before making a costly mistake and choosing the wrong size air conditioner, seek help from a qualified air conditioner installer to do an assessment. While room size is a major factor there are other factors to consider such as the number of people and the level of activity. Other elements that might influence the size includes direct exposure to sunlight and the type of building construction.
