A new aircon, installed properly
A good installation is about more than mounting a unit on a wall. The right size for the room, a sensible position for the indoor and outdoor units and a neat, sealed pipe run all affect how well your aircon cools, how much electricity it uses and how long it lasts.
What the installation involves
- Sizing: matching the unit's capacity to the room size and how the room is used.
- Placement: an indoor position that spreads air evenly, and an outdoor position with airflow and access for servicing.
- Installation: mounting, the pipe and cable run between the units, condensate drainage and the electrical connection.
- Testing: the system is checked and running before you are handed the remote.
For your home
Bedrooms, lounges, open-plan living areas and home offices. Share the room size, the use of the room and your suburb so the team can understand the job. Many units can also heat in winter. Ask about this when you enquire.
For your business
Offices, shops, consulting rooms and other business premises. Describe the space, how many people use it, any equipment that gives off heat and whether existing systems need replacing.
Replacing an old aircon
An old unit that is noisy, struggles to cool or keeps breaking down may cost more to keep running than to replace. Ask about removing the old unit and installing a correctly sized new one.
Quick sizing guide
A rough starting point using 600 BTU/h per m² for one enclosed room. The installer confirms the right unit after assessing the space.
- Up to 15 m² (small bedroom, study): about 9,000 BTU/h
- 15–20 m² (main bedroom): about 12,000 BTU/h
- 20–30 m² (lounge, small office): about 18,000 BTU/h
- 30–40 m² (open-plan living, larger office): about 24,000 BTU/h

Problems a good installation avoids
- A unit that is too small and runs flat out without cooling the room
- Water dripping inside because of poor drainage
- Noise and vibration from a badly mounted outdoor unit
- Uneven cooling and higher electricity use from a poorly placed indoor unit
