Choosing an air conditioning system can feel overwhelming. There are dozens of brands, multiple system types, and a wide range of price points — and the wrong choice can cost you significantly in energy bills and maintenance down the track.
At Alby Cool, we've been helping Frankston and Mornington Peninsula homeowners make this decision for over 25 years. Here's our straightforward guide to the main options and how to choose the right one for your home.
The main types of air conditioning systems
1. Split system air conditioner
A split system consists of one indoor unit mounted on the wall and one outdoor unit. It heats and cools a single room or open-plan area efficiently and is the most popular choice for Australian homes.
Best for:
• Single rooms, bedrooms, or open-plan living areas
• Homes where whole-house cooling isn't needed
• Budget-conscious buyers — split systems are generally the most affordable to purchase and install
• Renters or homeowners who want a targeted solution
2. Multi-head split system
A multi-head system uses one outdoor unit connected to multiple indoor units throughout the home. Each room has its own unit and can be controlled independently.
Best for:
• Homes where you want to cool or heat multiple rooms without ducted installation
• Avoiding the cost and disruption of ducted installation in an existing home
• Homeowners who want zone control without a full ducted system
3. Ducted reverse cycle air conditioning
Ducted systems use a central unit — usually in the roof cavity — connected to vents throughout the home. A single system heats and cools every room, controlled via a central panel or app.
Best for:
• Larger homes where whole-house comfort is the priority
• New builds where the ducting can be installed during construction
• Homeowners who want a discreet, aesthetically clean solution with no visible wall units
• Properties where resale value is a consideration — ducted systems add significant value
4. Ducted gas heating
Gas ducted heating uses a central gas furnace to push warm air through vents throughout the home. It heats quickly and efficiently, particularly in Victoria's colder winters.
Best for:
• Homes in cooler areas of the Mornington Peninsula where heating is the primary concern
• Homeowners who want fast, powerful warmth throughout the whole house
• Properties already connected to gas
Note: The Victorian Government is currently offering generous rebates for homeowners who replace gas ducted heating with an energy-efficient reverse cycle system — potentially saving up to $5,530. Ask us about this when you call.
Key questions to ask before deciding
Before choosing a system, it's worth thinking through a few practical questions:
• How many rooms do you need to heat or cool? A single bedroom needs a very different solution to a five-bedroom home.
• What is your budget — both upfront and ongoing? Ducted systems cost more to install but can be cheaper to run long-term when sized correctly.
• Do you rent or own? Renters may need landlord approval and typically can't install ducted systems.
• How old is your home? Older homes may need additional work to accommodate ducting.
• Are you eligible for a Victorian government rebate? The VEU program can significantly reduce your upfront cost.
What about brands?
At Alby Cool we supply and install all major brands — Daikin, Mitsubishi Electric, Fujitsu, Panasonic, and more. We're also an authorised Braemar Dominator dealer for premium ducted gas heating installations.
Our honest advice: the brand matters less than choosing the right system type and having it correctly sized and installed. An undersized or oversized system — regardless of brand — will cost you more to run and wear out faster.
Get expert advice before you buy
The best way to choose the right system is to have an experienced technician assess your home — room sizes, insulation, ceiling height, orientation, and usage patterns all affect which system will work best for you.
