Ducted vs Split System Cost Comparison in Canberra (2026)
In Canberra the ducted-versus-split choice is driven by heating, because whole-home ducted reverse-cycle warms the house through the frosty winter.
Single wall split
- Typical installed cost
- $1,800 to $4,200 supplied and installed for a 2.5 to 7.1 kW head
- Annual running cost
- $180 to $450 a year for a living area used most evenings
- Expected lifespan
- 10 to 15 years, often 12 in coastal air
- Install time
- Half a day, usually one crew, no ceiling work
- Maintenance
- Wash the filters every few months, pro service every 2 to 3 years
- Best climate fit
- Anywhere. The default choice in mild coastal and apartment settings
- Resale impact
- Neutral. Buyers expect it, they do not pay extra for it
Multi-split (3 to 5 heads)
- Typical installed cost
- $6,500 to $14,000 for three to five indoor heads on one or two outdoor units
- Annual running cost
- $450 to $1,000 a year, lower than ducted if you only run one or two heads
- Expected lifespan
- 10 to 15 years, but heads fail individually rather than all at once
- Install time
- Two to four days depending on pipe runs and wall penetrations
- Maintenance
- Filters per head, so more units to clean, roughly $250 a service visit
- Best climate fit
- Strong everywhere. The only realistic option in homes with flat or no roof cavity
- Resale impact
- Mildly positive, especially in apartments and renovated terraces
Ducted reverse cycle
- Typical installed cost
- $9,000 to $18,000 for most 3 to 4 bed homes, $17,000 to $25,000+ double storey
- Annual running cost
- $600 to $1,300 a year with zoning, materially more without it
- Expected lifespan
- 12 to 20 years on the unit, ductwork often outlasts two units
- Install time
- Three to five days, plus electrical and possible switchboard work
- Maintenance
- Annual filter and coil service around $250 to $400, duct checks every few years
- Best climate fit
- Best in hot dry inland and cold southern climates where whole-home load is real
- Resale impact
- The clearest positive of the three, frequently named in listing copy
What a ducted vs split system cost comparison costs in Canberra
The ducted-versus-split decision in Canberra is driven mainly by heating, because the cold, frosty winters mean a home needs reliable whole-house warmth for months, and a ducted reverse-cycle system heats every room evenly through one central unit, which suits the climate far better than trying to warm a whole house with a split in each room. Split systems still work and cost much less to install, but heating a large, cold home room by room is less comfortable, so the big temperature range tends to tip Canberra homes toward ducted where the budget allows.
The counterweight is cost, because ducted is a much bigger install and Canberra's high local labour base lifts it further, so a smaller home or one where only the living area and a bedroom need conditioning may sensibly choose splits. Zoning a ducted system is important to avoid heating empty rooms through the long winter. Many ex-government homes were built with ducted systems or gas ducting that can be converted, giving a head start on ducted. A well-insulated home makes either system cheaper to run across the frost. The dry summers mean cooling is a lighter, secondary consideration.
Both systems are licensed to install: a licensed refrigeration or ARC-certified technician handles the refrigerant and a licensed electrician the wiring, under Access Canberra for the electrical side. Ducted is the larger job through the roof space. For a Canberra home, the clearest way to make the ducted-versus-split decision is whole-home even heating for the frosty winter, budget permitting, versus cheaper room-by-room splits.

Frequently asked questions
Does Canberra's winter favour ducted?
Often. The cold, frosty winters mean a home needs reliable whole-house warmth for months, and a ducted reverse-cycle system heats every room evenly, which suits the climate better than warming a whole house with a split in each room in Canberra.
When do splits suit a Canberra home?
When cost rules or only part of the home needs conditioning: ducted is a much bigger install and Canberra's high local labour base lifts it, so a smaller home or one needing only a living area and a bedroom conditioned may sensibly choose splits.
Do ex-government homes help with ducted in Canberra?
They can. Many ex-government homes were built with ducted systems or gas ducting that can be converted to reverse-cycle, giving a head start on a ducted install rather than running ducts into a home from scratch in Canberra.
Do I need a licence to install either in Canberra?
Yes. Both are licensed: a refrigeration or ARC-certified technician handles the refrigerant and a licensed electrician the wiring, under Access Canberra for the electrical side, whether ducted or split.
