A single large zoned ducted system
One indoor unit, one outdoor unit, with zones for each area of the house.
Our take: Simpler and usually cheaper to install, and works well when zoning is designed properly. Ducted →

Air Conditioning Barden Ridge Sized for Big Family Homes
Barden Ridge was established in 1996, and the suburb is full of large family homes, many over two storeys. The big question here is usually whether one ducted system can do the whole house, or whether two will do it better.

Air conditioning in Barden Ridge usually means cooling and heating a big home. Many houses here are large two-storey builds from the late 1990s onwards, with media rooms, home offices and bedrooms spread over two levels. That raises a practical choice between one large zoned system and two separate ones. Alpha & Omega has designed both across the Shire since 1989.
The big decision
One Ducted System or Two for a Barden Ridge Home?
Both can work well. It comes down to how the house is laid out and how your family uses it.
Separate upstairs and downstairs systems
Each level gets its own indoor and outdoor unit.
Our take: Better when both levels are used at the same time, and you still have one system if the other needs repair.
Ducted plus a split or two
A main ducted system with splits in rooms used at odd hours.
Our take: Good for a home office, gym or media room that runs when the rest of the house does not. Splits →
Original ducted that struggles upstairs
A common complaint in larger two-storey homes.
Our take: Check sizing, ducts and zoning first. Sometimes the fix is a second system for upstairs. Service →

Comparing One System and Two
A quick comparison to help you think it through before we visit.
| Consideration | One zoned system | Two separate systems |
|---|---|---|
| Upfront cost | Usually lower | Usually higher |
| Running both levels at once | Works, but shares one unit's capacity | Each level has its own full capacity |
| If a unit breaks down | Whole house affected | The other level keeps running |
| Outdoor space needed | One outdoor unit | Two outdoor units |
Upstairs bedrooms still hot at bedtime?
In big two-storey homes, the upstairs often needs more cooling than the original system was designed for. A second system for upstairs is often the cleanest fix.

Barden Ridge FAQs
Air Conditioning Questions From Barden Ridge
Should a two-storey house have one air conditioner or two?
It depends on the layout and how you use the house. One large zoned system usually costs less upfront. Two systems give each level full capacity and a backup if one fails.
Why is my upstairs always hotter?
Upstairs rooms sit under the roof and collect rising heat, so they need more cooling. Undersized systems, leaking ducts or poor zoning make it worse.
Can I add a second system to my existing ducted setup?
Often, yes. A separate system for upstairs is a common upgrade in larger homes, as long as there is roof space and a suitable spot for another outdoor unit.
What size system does a large home need?
It depends on floor area, insulation, glazing, orientation and how many rooms you want to run at once. We calculate it room by room rather than relying on floor area alone.
Is zoning worth it in a big house?
Yes. Zoning lets you switch off areas that are not in use, which keeps running costs down in large homes.
Which licences cover your installs?
ARC refrigerant licence AU54289, and NSW contractor licence 329810C.
