What Size Split System Do I Need For My Home?

 Selecting the right air conditioner for your home or work is not always a simple process, different system styles work best for different properties and it depends too on things like budget, cooling needs, space, placement and more. When it comes to split systems in particular the professionals you hire for installment will look at split system sizing being based on energy efficiency and room size. This is the best way to keep it efficient both in terms of cooling and in energy use. When you buy an air conditioner with a larger capacity for cooling it needs to use more energy in order to work. But get something too small with not enough capacity and it won’t cool the room it is in well enough.

Looking at what size split system do I need

Whatever tyle of air conditioner you need you will need to factor in size and wattage. On average a place will need 0.15 kW per square meter. So if you have a small room at 20 square meters this will need an air conditioner with at least 3kW. You could also use a split system air conditioner size calculator to help work it out. Any professional with experience will know how to work it out and be able to offer good advice.

Looking at how to calculate split system size will see you best match the air conditioner and its size to the right room size.

1. Small rooms measuring 10 to 20 square meters need a minimum Kilowatts of 2.8. This is where a smaller split system, or a window box or portable might suit.
2. Medium rooms measuring 20 to 40 square meters need a minimum Kilowatts of 4.2. This would mean a split system or window box would work but not a portable one.
3. Large rooms of 40 to 60 square meters need a minimum Kilowatts of 5.6. This is going to need ideally a split system for maximum efficiency.

Take advantage of an expert’s advice

As you can see the split system sizing chosen really largely depends on the size of the area you are cooling. Measure the floor space of where you want to cool, measuring the length and the width. Make sure you take very accurate measurements and double-check them. Multiply the width by the length to get the square meter measurement but also take into account the ceiling height as that will impact the cooling efficiency as well. When you shop for air conditioners it is a good idea to have the help of a professional to offer you advice on what you need. They are grouped according to their output capacity from 1.65 kW smaller window box air conditioners up to reverse split systems at 9.2 kW. You will need about 1 to 1.5 kW of capacity per 10 square meters. If there is a high roof you might need more, if you live somewhere especially hot you might need more and if it is not very insulated then you also might need more.
