Ducted Heat Pumps in Hamilton
One system, warm air through every room, and nothing on the wall but a slim vent. Good for new builds and larger homes across Rototuna, Flagstaff and Cambridge.
A ducted heat pump hides in your roof and pushes warm air through vents into every room, run from one controller. It heats a whole Hamilton home evenly, clears damp Waikato winter chill from cold back rooms, and stays quiet with no boxes on the walls.
How a ducted system heats the whole house
The main unit sits in your roof space. Insulated ducts run out to a vent in each room, and a controller in the hallway sets the temperature. You warm the whole house from one place instead of chasing heat around with separate units.
That suits our damp Waikato winters. Cold back bedrooms and the condensation you wipe off windows come from uneven heat, and moving warm air through every room evens things out. Modern subdivisions in Rototuna, Flagstaff and Cambridge usually have the roof height to make it work cleanly. If you want to compare it against wall units and other options first, have a read of the different types of heat pump.
Which homes are a good fit
Ducted works best in newer homes with a decent gap between the ceiling and the roofline, which is why the new builds on the Waikato plains are ideal. If you're building or renovating, running the ducts before the linings go up is far tidier and cheaper than doing it later.
Older or single-storey homes with a shallow roof can be tight. In those cases a ceiling cassette heat pump or a couple of well-placed high-walls often does the job for less. We'll tell you straight which way makes sense for your place. A ducted setup can also handle cooling, so it doubles as air conditioning through summer.
- One controller for the whole home
- Nothing on the walls, just slim vents
- Even heat that clears damp and condensation
- Cooling in summer from the same system
- Zoning so you don't heat empty rooms
Sizing and getting the install right
Ducted lives or dies on sizing and duct layout. Too small and it never keeps up on a cold Waikato morning; too big and it short-cycles and wastes power. We work out the load from your floor area, ceiling height, insulation and window sizes before we quote anything. You can get a rough idea yourself with our heat pump sizing calculator.
The install itself takes longer than a single high-wall because we're running ducting through the roof and cutting vents in each room. It's worth getting the plan right up front. Here's what's involved in a proper heat pump installation in Hamilton.

Ducted heat pump questions, answered
How much does a ducted heat pump cost in NZ?
A ducted system for a typical Hamilton home usually runs from around $12,000 to over $20,000 fitted, depending on the number of rooms, zoning and how easy the roof access is. New builds tend to sit at the lower end because the ducts go in before the linings. For a full breakdown see our page on heat pump installation cost at heat pump installation cost.
Is a ducted heat pump better than multiple high-wall units?
It depends on the home. Ducted gives you even heat everywhere from one controller and nothing on the walls, which suits larger or new homes. Several high-walls can be cheaper to fit and let you heat one room at a time, which suits smaller or older houses. If you've got the roof space and want whole-home comfort, ducted usually wins on feel.
Can you retrofit a ducted heat pump into an existing house?
Yes, but it's more work than a new build. We need enough roof height to run the ducts and reasonable access to each room's ceiling. Single-storey homes with a shallow roof can be difficult, and in those cases a cassette or high-wall setup is often the better call. We'll have a look and tell you if it's practical.
