Choosing a modern, energy-efficient heating and cooling system is one of the best ways to improve comfort in your home or business while also reducing long-term energy costs. New systems can offer advanced climate control, improved air quality and significantly better efficiency compared to older models – especially when replacing outdated ducted gas systems.
At O'Brien Electrical & Plumbing Rowville, we supply and install high-performance split, ducted and multi-head heating and cooling systems tailored to your space. To help familiarise yourself with available options, below is a breakdown of our most popular systems and their indicative pricing.
Ducted Air Conditioning Systems
Ducted systems provide whole-home comfort with discreet vents and centralised temperature control. New ducted systems come with zoning capabilities, allowing you to control when and where heating or cooling occurs – so you can customise comfort room by room and reduce energy use in unoccupied areas. Many models also offer remote access via an app, giving you full control of your home’s climate from anywhere. Ducted systems are ideal for larger homes or those seeking consistent climate control throughout. Our team’s most popular selection is below:
