Choosing the right air conditioning system can make a big difference in your home’s comfort, energy bills, and design. Whether you’re upgrading an old setup or installing from scratch, it’s important to weigh the pros and cons of split systems versus ducted air conditioning. In this guide, we explore how each system works, their benefits, and which one may suit your property best.
Choosing Between Split Systems and Ducted Air Conditioning
What Is a Split System?
Split systems include one outdoor unit (housing the compressor and condenser) connected to one or more indoor units (containing the evaporator). These are designed for individual rooms or small spaces.
Pros:
- Lower upfront cost: Easier and more affordable to purchase and install.
- Flexible installation: Ideal for cooling or heating one room at a time.
- Energy efficient for single areas: Great for targeted use without high running costs.
Cons:
- Limited coverage: Not suitable for whole-home temperature control without multiple units.
- Visible units indoors: Wall-mounted units may impact interior aesthetics.
Installation Overview:
Installation involves mounting the indoor unit, securing the outdoor unit on the ground or wall, and connecting the two. It requires minimal structural changes and usually takes less than a day per unit.
What Is Ducted Air Conditioning?
Ducted systems use a central unit (installed in a roof space or outside) connected to ductwork that runs throughout the home, distributing air to each room via ceiling or wall vents.
Pros:
- Whole-home coverage: Uniform heating or cooling across multiple rooms.
- Discreet design: Vents are flush with ceilings or walls for a cleaner, quieter finish.
- Zoning options: Control different temperatures in different rooms for efficiency.
Cons:
- Higher installation cost: Requires ductwork and more extensive labour.
- More space needed: Needs sufficient roof or ceiling cavity for ducts.
Installation Overview:
Installing a ducted system is more involved. It includes setting up the central unit, routing ductwork, installing vents, and configuring the control system. This process may take several days and might require structural modifications, especially in existing properties.
Energy Efficiency and Costs
Split Systems
Efficient for spot cooling or heating, especially in homes where only one or two rooms need conditioning. However, installing several units can reduce efficiency and increase maintenance.
Ducted Systems
Zoned ducted systems can be highly efficient when used correctly, offering whole-home comfort without heating or cooling empty rooms. If misused, however, running costs can be higher due to system size.
Indoor Air Quality and Noise
Split Systems
Provide basic air filtration and are generally quiet, though some indoor noise may be noticeable depending on the unit’s location.
Ducted Systems
Offer superior air filtration and are quieter inside the home, with most noise isolated to the external or roof-mounted unit.
Maintenance and Lifespan
Split Systems
Require regular filter cleaning and periodic servicing of the outdoor unit. Typically last around 12 to 15 years.
Ducted Systems
Need duct inspections and filter replacements. With proper maintenance, they can last up to 20 years or more, especially in homes with consistent use and regular servicing.
