Choosing an Air Conditioner
Air Conditioning unit sizes are measured in BTU (British Thermal Unit) It is the measurement of heat extracted from the air per cubic meter over time, hence the cooling/heating capacity of the air conditioner. Rooms with windows, skylights, no ceiling void or other heat load generating factors may require you to upsize on the unit’s BTU’s.
Calculating the area size of a room to determine the size of Air Conditioner required?
EXAMPLE: Length 6m x Width 3m = 18sq m x 500 = 9000BTU required for the area size only.
Room Size |
Aircon Size Required |
|
Up to 18m² | 9 000 BTU | |
20 – 25m² | 12 000 BTU | |
30 – 36m² | 18 000 BTU | |
40 – 45m² | 24 000 BTU | |
55 – 60m² | 30 000 BTU |
Note: The BTU table above is meant to be used only as a general guide, as several factors may affect the cooling BTU’s needed like the height of ceilings and poor insulation etc.
If you are uncertain about the model appropriate for your application or undecided between models, always size up. Your system will not have to work as hard and will run more efficiently and at the same time use less electricity to achieve the desired effect.

Technology. Non-Inverter or Inverter?
A non-inverter air conditioner unit has a fixed speed compressor motor. Unlike inverter units, they work on an “all or nothing” principle meaning the compressor automatically goes on and off rather than running at a full speed all the time.
The compressor automatically switches off when the desired temperature is reached and starts again when the temperature increases.
Because of the frequent on-off cycles, the compressor always works at high power which creates a lot of noise while running thereby consuming more electricity making them less energy efficient than their inverter counterparts.
An inverter air conditioner unit has a variable speed compressor motor that adjusts the refrigerant flow inside the unit to control its cooling and heating capacity as required. The speed of the compressor motor in an inverter unit is directly proportional to the frequency of the power supply.
It uses a variable frequency censor to control the speed of the motor which in fact regulates the refrigerant flow inside the unit to provide just the right amount of cooling or heating as needed. This eliminates the frequent start-stop cycles thereby increasing energy efficiency of the unit in the long run.
Service, Repair and Maintenance.
We cannot emphasize this enough. Regular service and maintenance of your air conditioner will prolong the lifespan of your unit.
It is important to service your aircon annually to maintain your warranty on parts and to ensure it keeps running at peak performance and keeps energy costs down.
We have the experience and expertise to diagnose and repair commercial and residential air conditioning units. Our best solution will restore comfort to your home or office.
