Why Use an Air Conditioning Size Calculator?

Why is there a need for a split system size calculator? Or a ducted air conditioning size calculator?

An AC unit that is too big or too small for your layout can reduce the system’s lifespan and result in damaging consequences such as overheating, inconsistent temperatures, higher power consumption and poor air quality.

With our air conditioning size calculator for Australia, you can determine a more accurate unit size approximation for your location.

What AC Best Suits Your Property Layout?

Do you know what air conditioning & cooling system best suits your individual needs and home layout?

  • Split-system – Ideal for an open-plan space or one room.
  • Multi-split – Ideal for multiple rooms that are close together.
  • Ducted – Ideal for cooling and heating the entire property.
  • Wall-mounted – Similar to a split system, these are ideal for open-plan spaces or one room.

How to Prepare for Aircon Installation

  1. Consider where you want your AC unit and controller placed on your property. Your installer may also recommend placements for either system to consider wiring and other technical factors.
  2. Place dust coverings on your carpet, furniture and other valuable items.
  3. Move furniture and items out of the way before the installer arrives to give them space to work with and minimise damage or injury.

Installation is as critical as the make and model of AC unit you pick. Improper installation will not only void the manufacturer’s warranty but can also damage your unit in various ways. Consult professionally trained and licensed technicians like the Easy Cool Air team to handle your AC installation. Contact us to get started.
