What Are Ducted Heat Pumps?
Professional installation of ducted whole-home heat pump systems throughout Papatoetoe and South Auckland. One central unit distributes conditioned air through ceiling or floor vents to every room in your home.
Ducted systems provide invisible climate control – no wall-mounted units, just discrete vents delivering consistent temperature throughout the entire house. Ideal for new builds, major renovations, or homes requiring whole-home heating solutions.
How Ducted Systems Work
A single outdoor unit connects to one central indoor unit (typically installed in ceiling space or under the floor). The indoor unit distributes heated or cooled air through a network of insulated ducts to vents in each room.
Key components:
- Outdoor heat pump unit
- Central indoor air handler
- Insulated duct network throughout ceiling/floor space
- Supply vents in each room (ceiling or floor mounted)
- Return air grilles for air circulation
- Zone control panels (2-6 zones typical)
Each zone can be controlled independently, allowing different temperatures in bedrooms versus living areas, or switching off unused spaces to save energy.
What’s Included in Installation
All ducted installations include:
- Complete system design and heat load calculations
- Outdoor unit installation with proper drainage
- Central indoor air handler unit
- Full duct network design and installation
- Supply vents and return air grilles
- Zone control system with wall controllers
- Electrical connections and circuit protection
- System commissioning and airflow balancing
- Full demonstration and handover
- 5-year installation warranty
- Manufacturer warranties on all equipment
Pricing and Investment
Ducted systems require higher upfront investment than wall-mounted units but provide whole-home coverage from one integrated system.
Typical pricing for Papatoetoe homes:
- 3-bedroom home (120-150m²): $12,000-$18,000
- 4-bedroom home (150-200m²): $16,000-$24,000
- 5+ bedroom home (200m²+): $22,000-$35,000
Final pricing depends on home size, duct complexity, zone requirements, ceiling/floor access, and brand/model specifications.
Cost vs. Multiple Wall Units
For whole-home heating, ducted systems typically cost less than installing 4-6 individual high wall units throughout a home. Operating costs are also lower due to integrated system design rather than multiple separate units.
Government Subsidies
Eligible homeowners can receive support through Warmer Kiwi Homes programme. As an EECA-approved provider, we handle applications and compliance requirements. Check subsidy eligibility criteria.

Ducted vs. Multi-Room Systems
Ducted advantages:
- Completely invisible (no wall units)
- Even temperature distribution throughout home
- Better for open-plan layouts
- Integrated ventilation options
- Cleaner interior aesthetics
Ducted limitations:
- Requires adequate ceiling or underfloor space
- Higher installation complexity
- Less flexible for staged installation
- If central unit fails, whole system affected
Alternative: Multi-room systems offer visible wall units with independent operation – better for retrofits or staged installations.
Installation Requirements
Space requirements:
- Minimum 600mm ceiling cavity height for standard ducting
- Adequate underfloor access if ceiling unsuitable
- Space for central indoor unit (typically 1.2m x 0.8m x 0.6m)
- Outdoor unit placement with proper clearances
Suitable properties:
- New builds and major renovations (ideal)
- Existing homes with accessible ceiling/floor space
- Homes with consistent ceiling heights
- Properties requiring whole-home solutions
Most Papatoetoe homes built after 1960 have adequate space. Older properties require individual assessment.

Zone Control Benefits
Modern ducted systems divide homes into 2-6 independently controlled zones. Typical zoning:
- Zone 1: Living areas (lounge, dining, kitchen)
- Zone 2: Master bedroom suite
- Zone 3: Secondary bedrooms
- Zone 4: Additional rooms or separate living spaces
Zone control advantages:
- Different temperatures for sleeping vs. living areas
- Disable zones in unoccupied spaces
- Reduce energy waste heating/cooling empty rooms
- Customise comfort for different family members
Installation Process
Most residential ducted installations complete in 2-4 days depending on home size and duct complexity.
Installation stages:
- Site survey and final duct design confirmation
- Outdoor unit installation
- Central indoor unit installation in ceiling/floor space
- Duct network installation throughout home
- Vent and grille installation in each room
- Electrical connections and zone control wiring
- System commissioning and airflow balancing
- Complete testing and demonstration
We protect all floors and furnishings, coordinate with other trades if required, and clean up thoroughly upon completion.
Maintenance Requirements
Annual professional servicing maintains efficiency and system longevity. Ducted systems require more comprehensive maintenance than wall units due to duct network and central air handler.
Annual service includes:
- Filter replacement (central return air filters)
- Indoor coil cleaning and inspection
- Outdoor unit coil cleaning
- Duct inspection for leaks or damage
- Zone damper operation verification
- Refrigerant pressure checks
- Electrical connection inspections
- Airflow measurement and rebalancing
- Zone controller calibration

Is a Ducted System Right for You?
Ducted systems work best for whole-home heating requirements in properties with adequate ceiling or underfloor access. Best suited for new builds, major renovations, or replacing existing ducted systems.
For smaller homes or single-room requirements, high wall units starting from $2,500 may be more cost-effective.
Service Areas
We install ducted systems throughout Papatoetoe, Flat Bush, Manukau Central, East Tamaki, and surrounding South Auckland areas.
All installations comply with New Zealand building standards with EECA-approved installation and 5-year workmanship warranty.
