Air Conditioning Kogarah Bay One System Per Dwelling, Done Right
Kogarah Bay sits on the water south of Kogarah, and many older houses here have been replaced with duplexes and townhouses. Each dwelling needs its own air conditioning, planned around shared walls, narrow side setbacks and limited outdoor space.
Updated October 2026
Air conditioning in Kogarah Bay is increasingly about duplexes and townhouses. Every dwelling needs its own independent system and power supply, outdoor units must fit narrow setbacks without bothering next door, and duct runs need planning before ceilings close up. We work with owners and builders to get each side right. Alpha & Omega has installed systems across Sydney since 1989.

Does each side of a duplex need its own air conditioner?
Yes. Each dwelling should have its own independent system, controls and power supply so owners or tenants are not sharing equipment.
Where should outdoor units go on a narrow duplex site?
Usually at the rear or in a side setback away from the shared wall and neighbouring bedrooms, with room for airflow and servicing.
When should air conditioning be planned in a duplex build?
Before the frame is up and well before plaster, so ducts and pipes can be roughed in neatly.
Is ducted or multi-split better for a townhouse?
Ducted suits townhouses with good ceiling space. Multi-split suits tight sites where one compact outdoor unit is needed.
Can you quote both dwellings together?
Yes. We can quote each dwelling separately within one proposal.
Which licences cover your installations?
We install under ARC licence AU54289 and NSW contractor licence 329810C.
