A heat load calculation comprises of many factors such as size of area, size of windows, roof type, building material, whether there is insulation, external shading or internal shading etc. Incorrect sizing will mean inadequate cooling/heating.

Most Air conditioning systems these days are of inverter type. Inverter air conditioners use a variable frequency drive to control the speed of the motor thus in turn the compressor. When the cooling demand is met the compressor will slow down, in return reducing running costs.

Inverter air conditioners reach the desired room temperature faster, and then constantly adjust to maintain perfect comfort. Inverter air conditioners are more economical to operate and quieter to run than fixed speed units but need to be correctly sized.

This refers to energy efficiency rating and measures the air conditioners energy consumption and efficiency. A higher EER rating on your air conditioning system means the system is more energy efficient. You can compare the ratings from each manufacturer.

This simply means that the system is able to both cool and heat.

MEPS stand for Minimum Energy Performance Standards which have been introduced by the Australian government. All systems sold by Airconditioning – Online meet MEPS requirements. This energy rating is mandatory.

All systems sold by Airconditioning-Online have a 5 yr manufacturers warranty. For more details refer to each Manufacturers warranty guidelines.
