Heat pump installation cost in Whangarei
Here's what a heat pump actually costs to buy and fit in a Northland home, and what pushes the number up or down. No surprises when the quote lands.
A single high-wall heat pump supplied and installed in Whangarei usually runs about $2,500 to $4,500. Multi-room and ducted systems climb from there, often $6,000 to $15,000-plus depending on size, layout and how tricky the run is. A proper quote beats any ballpark.
What actually moves the price of a heat pump install
The unit itself is only part of it. Two homes in Kensington can get the same model and pay different prices because the install is different. The big drivers are how far the indoor and outdoor units sit apart, how easy the pipe run is, whether we're going through a cavity or up into a roof space, and the electrical work at your switchboard.
Coastal homes out at Ruakaka and Waipu are their own thing. Salt air chews through cheaper outdoor units, so we'll often spec a coated, corrosion-resistant model that costs a bit more up front and lasts a lot longer than saving a few hundred dollars and replacing it early.
- The heat pump model and its heating output (kW)
- Distance and difficulty of the pipe run between units
- Mounting height and access, including roof or subfloor work
- Switchboard and wiring changes if your board is full or old
- Corrosion-resistant units for coastal salt exposure
- Removing and disposing of an old unit if there is one
One room, a few rooms, or the whole house
The cheapest way in is a single high-wall unit in the room you live in most. If you want more than one room off a single outdoor unit, multi split heat pumps run several indoor heads off one compressor, which suits a lot of the newer open-plan builds along Bream Bay. For a whole-home solution with hidden vents, ducted heat pump systems cost the most but heat every room evenly.
In an older bungalow with a cold slab or draughty floor, floor console heat pumps throw heat low and warm faster from a standing start. A good heat pump installation is what makes any of these actually perform, and the same gear does air conditioning in our sticky Northland summers, so you're buying year-round comfort, not just winter heat.
Why the right size beats the biggest or cheapest unit
It's easy to think heat pumps are all much of a muchness and the biggest one is the safe bet. They're not. An oversized unit short-cycles, never runs long enough to pull moisture out of the air, and leaves you with a warm but still-damp room. That matters here, because a correctly sized unit is what clears the condensation off your windows through a humid Whangarei winter.
Undersized is the other trap, and it's common in our older uninsulated bungalows around Raumanga and Kamo. Those homes lose heat fast and need more output than the room's floor area alone suggests. Sizing and install quality move the outcome far more than which brand's badge is on the wall. Run your rooms through our heat pump sizing calculator for a rough output, then we'll confirm it on site.
The Warmer Kiwi Homes grant and getting a real number
Some households qualify for help. The Warmer Kiwi Homes grant covers up to 80% of the cost of an approved heater, capped, if you own and live in the home and hold a Community Services Card or live in a lower-income area. You apply through EECA, not through us, and they confirm what you're eligible for.
Beyond that, the only honest price is a quote for your house. We'll look at the rooms, the layout and the run, and give you a fixed figure with no moving parts. If you'd rather talk it through first, call us on 09 434 1234.

Send us the rooms you want warm and roughly where you are, from the harbour suburbs out to the coast, and we'll come back with a straight price.
Common questions about heat pump cost
How much does it cost to install a heat pump in NZ?
For a single high-wall unit supplied and installed, most homes pay somewhere around $2,500 to $4,500 in NZ. Multi-room and ducted systems run higher, often $6,000 to $15,000-plus. The final number depends on the unit, the size you need and how involved the install is.
Is the price for supply and install or just the unit?
Our quotes are always supply and install, so the price covers the unit, the mounting, the pipe run, the electrical work and getting it running. A unit-only price from a retailer looks cheaper because it leaves out the labour, brackets, wiring and consumables, which is where a lot of the real cost sits.
How much does a ducted heat pump cost?
A ducted system is the priciest option because there's a lot more to it than a wall unit. Expect roughly $10,000 to $18,000-plus depending on the number of rooms, the size of the home and how much ductwork the roof space allows. New open-plan coastal builds are often the easiest and best-value candidates for ducted.
