Choosing the best air-con system for your home

Installing a new air conditioning unit might seem simple, but it can actually be more complicated than you think. If you’re in the market for a new air conditioning unit, make sure you know what unit is right for your space (and if you actually need one!).

Here’s some things to consider when looking for a new unit:

Ducted or split system?

There are a lot of advantages to ducted air conditioning: the ducts are hidden in the wall and only discreet panels are visible; and it’s a simple system to use where all you have to do is set the thermostat and your house will be at the perfect temperature. While ducted systems are more expensive to buy and install, their running costs can be offset over time.

A split system is designed for one room only, so is therefore less expensive to buy and have installed. Because they have lower energy demands, running costs on split systems are generally lower than ducted systems. Although cheaper, split systems are only designed to cool a single room, so if you want to have air con in multiple spaces, you may need to buy separate units for each room.

Other advantages of split systems:

  • Buying a split system is more affordable because you can add on to the system as your budget allows.
  • If one unit requires repair, the others continue working and repair costs are lower.
  • Replacement costs are lower.
  • Running costs are lower because split systems are used only when and where needed.

Size

Determine what size unit will cool the room most effectively: As a general guideline, you will need between 1 and 1.5 kilowatts power capacity per 10 square meters of space. This means that a 60 square meter space will probably require a conditioner with 6-9 kilowatts power capacity. This figure doesn’t take into account things like how tall your ceiling is, the effect of windows and doors, and the general insulation of the building

Energy rating

Like with any new appliance, it’s always advised to choose one with a high energy star rating. The more stars on the energy rating label, the more energy efficient the appliance is, which means it uses less electricity to run. Cheaper for you and better for the environment!

Cost

It’s easy to be tempted by cheap online deals, but while it may save your purse a few dollars, cheaper built models can lead to increased energy bills and regular maintenance.

Position

The position of your unit affects its effectiveness and efficiency. Find a location with shade and make sure it’s not situated in an area exposed to high temperatures. Doing so means your unit does not need to work harder than necessary to cool your home.
