Frequently Asked Questions

What size air conditioning system do I need?

It is important to get the right size. A system that is too small will have to work too hard and too long to reduce the temperature and remove the humidity from the air. A system that is too small will end up costing you more in increased power bills. A correctly sized air conditioning system will bring the temperature down steadily over a period of time and do it more efficiently. The best way to work out the size of system you need is to have Climatech carry out a Calculated Heatload Estimate on your home, office or building. This takes into account important factors such as room size, exposure to solar load (number of windows, exposure to western sun etc), the level of insulation in walls or ceiling and the building materials used in construction.

What is an ’inverter‘ air conditioner?

An inverter model means that the compressor is powered by a variable speed drive or ‘inverter’, which enables the compressor to run at a range of speeds from slow to fast, to match the output required. Most conventional compressors run at a constant speed and these types of units vary their capacity by switching on and off at different intervals. Inverters are a sophisticated piece of technology which improve the performance and energy efficiency of air conditioners under normal use. Inverter models are marked in the web site listing for air conditioners. See also the following question.

Does my air conditioning system require servicing?

Yes. For commercial clients, every month is a requirement. For residential customers that use their air conditioning sparingly, once a year is generally enough. Gas charges, electrical connections, electronics and drains are just a few of the checks carried out during a service. Regular checks keep your system clean and healthy.

What types of air conditioners are not required to carry an energy rating label?

The following air conditioners are not currently required to carry an energy rating label:

  • evaporative air conditioners,
  • three phase air conditioners (these may carry a label on a voluntary basis but are unusual for the residential sector),
  • multi-split air conditioners (units with several separate indoor units each with a separate control),
  • air conditioners intended purely for commercial applications and portable air conditioners.

See Requirements for air conditioners for a more detailed list of exemptions.

What does ‘Reverse Cycle’ mean?

Reverse Cycle refers to a single system that can provide both heating and cooling.
