A well-sized system with sealed ductwork, balanced airflow and careful commissioning will outperform a premium unit installed poorly.
Operating costs depend heavily on insulation, energy tariffs, weather, star rating and how well zoning is used.
| System type | Cost per hour | Annual cost | Efficiency |
|---|---|---|---|
| Ducted gas heating with zoning | $0.40-$0.80 | $300-$600 | Lowest |
| Reverse cycle ducted heating | $1.00-$2.00 | $400-$800 | Efficient |
| Multiple split systems | $0.50-$1.50 per unit | $200-$500 per unit | Good |
| Portable electric heaters | $2.00-$4.00 | $1,200-$2,400 | Poor |
Ducted suits premium whole-home comfort. Split systems can still be better for smaller or staged projects.
| Factor | Ducted Heating | Multiple split systems |
|---|---|---|
| Initial cost for a 4-bedroom home | $4,000-$8,000 gas or $10,000-$25,000 reverse cycle | $6,000-$12,000 |
| Aesthetics | Invisible ceiling grilles only | Visible wall units in each room |
| Running costs | 30-40% lower with zones used well | Higher if several rooms run at once |
| Property value | Premium whole-home feature | Useful but less integrated |
| Control and flexibility | Whole-home system with zones | Independent control per indoor unit |
| Installation requirement | Roof/subfloor access and duct layout needed | Easier retrofit for selected rooms |
| Maintenance | One system to service | Multiple indoor units to clean and service |
Understand common issues, likely causes and how annual servicing helps prevent bigger repair bills.
Cause: Thermostat issue, gas supply problem, electrical fault or pilot ignition issue.
Solution: Check controller settings, then book licensed diagnosis for gas/electrical faults.
Cause: Blocked vents, faulty zone dampers, duct leaks or unbalanced airflow.
Solution: Damper adjustment, duct sealing, airflow balancing or zone repair.
Cause: Dirty filters, duct leaks, poor insulation, oversized system or poor zoning habits.
Solution: Annual service, filter cleaning, duct sealing and better zone scheduling.
Cause: Loose ductwork, fan vibration, bearing wear or expanding duct material.
Solution: Secure ductwork, balance fan, inspect motor and replace worn parts.
Cause: Possible gas leak, valve fault, cracked heat exchanger or incomplete combustion.
Solution: Turn off gas, ventilate, leave the home and call the gas emergency line.
