Planning a fresh air system in Sydney with a new AC? Talk to Oregan Air Conditioning about adding the upgrade at installation.

A new air conditioner installation is the easiest time to ask whether outside air should be part of the design. If you are considering a fresh air system in Sydney, it can be added when the air conditioning unit is installed, so the layout is worked out once instead of revisited later. Oregan Air Conditioning is a family-run business based in Kenthurst, serving Sydney’s west.

How Does a Fresh Air System Work with Your Air Conditioner?

Our fresh air upgrade draws in outside air when it is cooler than 22°C and distributes it through the air conditioning system, without running the outdoor compressor. This mostly suits summer nights, when outdoor air cools down. In winter, the system can also draw in midday air that is warmer than the air inside the home.

That does not make it a replacement for cooling. On hot days the air conditioner still does the cooling, and how often outside air is useful depends on the weather and how you use the home. We do not quote energy saving figures without a source, so check the manufacturer’s information if you need performance data.

Why Plan a Fresh Air System in Sydney During the AC Installation?

Choosing a fresh air system in Sydney at the same time as the air conditioner keeps design, installation and access in one job. The two can be considered together from the start, instead of going back to alter completed work later.

It also gives you one conversation about what the home needs. We offer ducted air conditioning, split systems, zoning upgrades and fresh air systems, so the options can be compared in one place before you decide.

What Should You Think About Before Adding Fresh Air?

A fresh air upgrade should suit the home and should not be treated as a standard add-on. Points worth raising when you ask for a quote include:

  • Home layout: Room positions, storeys and access can all affect how the installation is planned.
  • Outdoor air intake: The intake needs a suitable position for drawing in outside air.
  • Air conditioning system: Confirm the upgrade suits the system you choose.
  • Outdoor conditions: Outside air only helps when it is cooler than the set temperature, so it is not a substitute for cooling in every condition.
  • Existing ventilation: Think about how the home already gets fresh air, such as openable windows and exhaust fans.

For general background, Part 10.6 of the NCC 2022 Housing Provisions covers ventilation for residential rooms and refers to both natural and mechanical ventilation. It sets out building requirements, so it is not a guide to choosing a system.
