Choosing An Air Conditioner:

Air conditioning prices varies depending on the brand, model of the air conditioning unit and many other factors. Many homes and offices around the world already have air conditioners installed due to the many benefits of having a comfortable home and working environment.

Factors to consider when choosing an Air Conditioner:


The air conditioning unit must be big enough to handle the job or else it will freeze up on the hottest days, sort of like leaving your freezer door open, and then it won’t be working on the days when you need it the most. If the unit is oversized it cycles on and off too frequently, preventing any effective airflow which results in an uncomfortable environment. This means that the system is not helping to control the temperature inside the home or office.

Price and quality:

There are two main factors that go into air conditioning prices: size and quality.

Those who want the best, most efficient (R410 inverter) units, are going to pay the most. Those who feel they can get by with a little less will find there are some products (Jet-Air) on the market for them as well.

There are other minor factors will also play a role in the costs and some consumers only have their eyes on a specific brand. At the end of the day everything can add up to a significant difference in air conditioning prices.

Installation cost:

The installation cost depends on the length of pipe runs, type of bracket used and specific site requirements, i.e. Condensate pump.

For a precise assessment of the correct size and type of air conditioner required, a qualified air conditioner installer will be need to do an on-site check, as there are a number of different factors to consider.

Estimation of approximate size of unit required:

The following information will however give you an approximate guide to the A/C capacity required for a particular area.
BTU – British Thermal Unit. It is the measurement of heat extracted from the air per cubic metre over time, and hence the cooling/heating capacity of the air conditioner.

NB : Rooms with windows, ski-lights, no ceiling void or other heat load generating factors may require you to upsize the air conditioner unit BTU’s.

The number of BTUs required to cool a given room is proportionate to the size, measured in cubic metres, of that room. Smaller rooms can operate efficiently with lower BTU ratings while larger rooms need higher BTU ratings.

First multiply the length of your room by the width, check the table below to estimate the size of unit required for a room with normal 2.6m ceiling height.

For a room of approximately: A/C Size Required:
15 to 20 m² :   9 000 BTU
20 to 25 m² : 12 000 BTU
25 to 35 m² : 18 000 BTU
35 to 45 m² : 24 000 BTU
45 to 60 m² : 30 000 BTU

Inverter Technology Explained:

Inverters (R410 gas, more environmentally friendly) are the pinnacle of energy efficiency due to the innovative operation. An inverter air conditioner can alter the compressor speed to cool down rooms quickly and more efficiently as they do not have the same “power spike” effect as non-inverter air conditioning units, due to the fact that the compressor doesn’t switch off – it merely runs faster or slower.

The inverter air conditioner works by continuously changing the compressor and fan motor speed to reach the required temperature quicker. Once the desired temperature is reached, the air conditioner adjusts its compressor speed up and down to maintain a constant temperature.

With the traditional air conditioners (R22 gas, non environmentally friendly) the compressor is either on or off, causing a spike in power usage on every cycle when it switches on.

Utilising R410A gas, inverter air conditioning units are very environmentally friendly as well as being extremely economical to operate.

  1.  Economical: uses up to 40% less electricity than a conventional air conditioner
  2.  Powerful: With the wide operating range for quick heating and cooling.
  3.  Comfortable: Maintain desired temperature with quiet operation.


Heating And Cooling

Modern air conditioners have a reverse valve (4way valve) that can be changed over using the remote mode key. This changes the gas flow direction, and allows for switching between heating and cooling modes.

Benefits of Modern Air Conditioners

Heating – Heat pump air conditioning is an energy efficient means of heating an area. The heat pump air conditioner will maintain a constant temperature regardless of the outside conditions. Provided with a temperature controller the temperature is easily modified and controlled.

Cooling – Increased productivity, improved comfort and better general feeling of wellbeing are some of the benefits of maintaining a comfortable temperature during hot summer months.
