Air conditioning factors to consider
Firstly, let's take a look at the factors to consider when deciding the best size of aircon for your needs:
- Room size: How large (or small) is the area you are trying to cool? Are you looking at cooling one room, or a whole home?
- Room type: Does the room have a lot of traffic? Is it a bedroom, study, kitchen or other area?
- Usage: How often will you be using the system? Will it be on every day, or only used occasionally?
- Capabilities: What do you require your system to do? Do you need reverse-cycle and were you considering ducting?
- Energy efficiency: What size system is the most energy efficient for your space?
- Upfront cost: What are the different purchase and installation costs associated with each system?
- Running costs: What are the ongoing running costs for the different-sized systems?
This list is in no way exhaustive, however it covers a lot of the major aspects to think about when looking at the best system size for your space.What size air conditioner is right for you? Talk to our electricians today and see how we can help you.

How much will an aircon of that size cost?
The cost of aircons can vary depending on a lot of things, however the following is a look at average air conditioning system purchase costs.
$500 to $1,000
$750 to $1,500
$1,000 to $1,800
$1,500 to $2,000
What about running costs?
According to Canstar Blue , Australian households spend around $240 a month on electricity when summer comes around. Although people believe that aircons are money burners, a lot of the time the energy costs of running an air conditioner are quite low:
- A split system aircon, or a window unit, can cost around 11-16c an hour for a 12m² room, 38-54c an hour for a 36m² room and 53-75c an hour for a 50m² room.
- A ducted system for a whole home (around 200m²) can cost around $2.26 - $2.67 per hour for energy.
Why is a correct-sized air conditioner so important?
Ensuring you have an aircon that is the correct size for your space doesn't just save you money, it also helps with energy efficiency and ensures the best system for the environment. In addition to all this, choosing an air conditioner that is the right size for an area will ensure you stay comfortable, no matter the weather outside... which is exactly what you purchased it for!
