Living in Logan and South Brisbane means dealing with sweltering summers where temperatures regularly push past 35°C and the humidity is a killer. If you’re running your ducted air conditioning throughout your entire home just to keep one or two rooms comfortable, you’re paying far more than you need to.
At ClimateLink, we’ve helped hundreds of Logan families solve this exact problem. After installing many Daikin ducted systems across South Brisbane, we’ve seen firsthand how proper zoning transforms both comfort and running costs.
What Is Ducted Air Conditioning Zoning?
Zoning divides your ducted air conditioning system into separate controllable areas, allowing you to cool or heat specific rooms independently rather than conditioning your entire home at once.
Think about it this way: you wouldn’t have one light switch controlling every light in your house. Your air conditioning shouldn’t work that way either.
Motorised dampers installed within your ductwork open and close to direct airflow precisely where you need it. These dampers connect to zone controllers that let you set what areas you want running when.
Modern Daikin systems can support up to eight zones with standard controllers, or up to ten zones with advanced systems like Advantage Air’s MyAir. The MyAir 5 will also allow you to accurately different temperatures in different zones.
Why Logan Homes Benefit from Zoning
Logan’s subtropical climate creates specific challenges that make zoning particularly valuable.
Multi-storey homes face the heat rise problem. In Logan’s summer heat, upstairs bedrooms can be 3-5°C warmer than ground floor rooms. Zoning lets you push more cooling power upstairs while maintaining perfect conditions below.
Sun exposure varies dramatically. West-facing rooms that cop the afternoon sun need far more cooling than shaded areas. Zoning allows you to deliver 100% airflow to high-heat zones while reducing flow to 50-60% in naturally cooler rooms.
Not every room needs constant conditioning. Guest bedrooms sit empty most of the time. Home offices are only used during work hours. Research shows you can save 30-40% on running costs by conditioning only the spaces you’re actually using.
The Real Numbers: Energy Savings from Zoning
When Logan families ask me about zoning, they want to know the actual savings.
A comprehensive study published in the journal Energy and Buildings showed energy savings ranging from 21% to 42% compared to non-zoned operation, with payback periods of 3.2 to 4.3 years. The U.S. Department of Energy estimates that properly designed HVAC zoning systems can save up to 30% on heating and cooling bills.
For a typical Logan home with a 14kW Daikin ducted system:
- Without zoning: $1,200-$1,400 annually
- With 30% zoning savings: $360-$420 saved every year
- Over 15-20 years: $5,400-$8,400 total savings
The investment in quality zoning equipment typically ranges from $1,500-$2,500 depending on the number of zones. This means your zoning investment pays for itself within 4-6 years, after which the savings continue year after year.
How to Design Your Zone Layout
Creating effective zones requires understanding both your home’s physical characteristics and how your family actually uses the space. Here’s what we look at:
Start with your home’s structure. Two-storey homes naturally divide into upstairs and downstairs zones as a minimum. Consider separating north and west-facing rooms that receive intense Queensland sun from cooler south and east-facing areas.
Map your daily usage patterns. Most families follow predictable patterns: living areas during the day, bedrooms at night. We often find zoning all bedroom separately gives the best flexibility.
Group rooms by similarity. Rooms sharing similar characteristics work well as a single zone—open-plan living areas together, or home office spaces used only during business hours.
Plan for a constant zone. With modern Zone controllers – forgot the traditional constant zone that is set-up as a ‘spill’ zone to prevent overloading your ductwork. All the Zone controllers we work with allow a minimum zone number set for safety and no zone needs tor un all the time.
Optimising Airflow with Percentage Control
Modern zoning systems offer percentage-based airflow control, allowing you to fine-tune exactly how much cooling each zone receives.
- High-heat zones (large windows, afternoon sun): Set to 100% airflow
- Standard zones (moderate cooling needs): 70-80% airflow
- Low-demand zones (hallways, rooms close to indoor unit): 50-60% airflow
The beauty of Daikin systems with modern controllers is that you can make these adjustments from your smartphone and find the perfect balance for your home.
Smart Controllers: Taking Control Further
Modern zone controllers have revolutionised how families interact with their ducted systems.
Advantage Air’s MyAir integrates seamlessly with Daikin systems, providing up to ten zones with individual temperature control. Create custom schedules, monitor real-time energy usage, and set motion sensors to automatically adjust zones when rooms are unoccupied.
Daikin’s Airbase Wi-Fi control puts your system at your fingertips through a user-friendly app, allowing complete remote operation via your home Wi-Fi.
These controllers learn your patterns and preferences over time. Imagine your home automatically cooling down 30 minutes before you arrive from work, or shutting off zones when no activity is detected.
Common Zoning Mistakes to Avoid
Through our work with hundreds of Logan homes, we’ve identified several common issues:
- Closing off too many zones simultaneously creates pressure problems— we balance and program your system so this cannot happen
- Poor sensor placement in direct sunlight or near doorways provides inaccurate readings
- Setting unrealistic temperature differences between zones—most systems work best with no more than 4°C variation
- Undersizing for future needs—planning ahead costs less than retrofitting zones later
Maintenance for Zoned Systems
Zoned systems require straightforward maintenance:
- Clean return air filters every 1-3 months during heavy use—Logan’s humidity can quickly clog filters
- Annual professional servicing to check dampers, clean the evaporator coil, ensure drains are flowing, and inspect the complete ductwork and refrigerant cycle
- Keep outdoor units clear with at least 100mm clearance on all sides and ~1m at the discharge fan
- Monitor zone performance for any zones struggling to reach temperature
At ClimateLink, our service plans ensure your zoned Daikin system continues operating at peak efficiency year after year.
Is Zoning Right for Your Logan Home?
You’ll benefit most if your home has:
- Two or more storeys where heat rise creates temperature imbalances
- Large floor area (over 150m²) where cooling the entire space is wasteful
- Rooms with varied usage patterns throughout the day or week
- Family members with different temperature preferences
- Areas with significantly different sun exposure
- Plans to install solar panels (zoning reduces system size needed)
