How to Determine What Size Air Conditioner You Need
First you will need to find out the size of the area you will be conditioning in square meters (m2), make sure you take into account any hallways or rooms which you cannot seal off.

Once you know how big the area is, use the table below to decide on the right air conditioner for you. Don’t forget, large windows, heat loading, ceiling heights and room use all play a part in calculating your unit size. If you’re not sure, contact our friendly staff.
- 2.0 kW – Approximately 13m2
- 2.5 kW – Approximately 17m2
- 3.5 kW – Approximately 23m2
- 4.4 kW – Approximately 29m2
- 5.0 kW – Approximately 33m2
- 6.0 kW – Approximately 40m2
- 7.1 kW – Approximately 47m2
- 8.0 kW – Approximately 53m2
- 9.4 kW – Approximately 63m2
Getting the right sized air conditioner is more important than you might think. Having a system that is too small can shorten the life of the air conditioner, since it has to work harder to heat or cool the room. This also means that it can take much longer to reach the temperature you want, or never get there at all. Your power consumption will also rise, meaning any savings you made on the initial cost of purchasing the system will eventually be outweighed by the increase to your electricity bill.
