Heat pump installation in Queenstown
Your installer will specify a unit rated to hold its output below zero and put it where it can still defrost and drain with snow against the wall, so it heats the house on the coldest mornings instead of struggling through them.
What it costs
These are fitted prices including GST: the unit, brackets, pipework, the electrical connection, commissioning and the tidy-up. A cold-climate model sits at the top of these prices rather than above them, and so does sizing up for a cold pocket.
| Type | Supplied & fitted | Suits |
|---|---|---|
| High-wall bedroom or small room | $2,200 to $3,200 | Around 2.5kW. The cheapest way to heat one room properly. |
| High-wall standard living area | $3,000 to $4,800 | A 5 to 6kW unit, which is where most homes here land. |
| High-wall large or open-plan | $4,200 to $6,000 | A 7 to 8kW unit for a knocked-through living, dining and kitchen space. |
| Floor console low stud or replacing a fire | $3,200 to $6,000 | Sits at skirting height, so it works where there's no usable high wall. |
| Multi-split 2 to 3 rooms | $5,500 to $10,000 | Living area plus bedrooms from one outdoor unit, which matters where only one spot is sheltered. |
| Multi-split 4 or more rooms | $10,000 to $14,500 | Enough heads to cover most of a larger home. |
| Ducted whole home | $14,000 to $28,000+ | Zoned and hidden in the roof. The spread depends on the number of zones and how easily the ducting runs. |
You'll get a firm price once your installer has the right measurements and details of your job. Costs can vary a lot, and the cost page goes into why.

How a heat pump installation works
A single high-wall is usually done in a day, start to finish.

Tell us your town, the rooms you want warm and roughly how the house is built. That's enough to come back with options and a price.
Site visit
Your installer walks the house, checks the glazing, insulation and how exposed the place is, and works out where the outdoor unit can live year-round.
The install
Three to five hours for a single high-wall. Multi-room and ducted work takes longer and gets scheduled in advance.
Commissioning
Tested, the electrical work certified, and you get shown how to run it, including what normal defrost behaviour looks like so a frosty morning doesn't worry you.
Which type of heat pump suits your home
A well-sized high-wall in the living area does the job in most homes here, and there's no sense buying more system than that. Where the whole house needs to hold a temperature, or there's no sensible wall, the other types of heat pump are worth comparing.
High-wall
The cheapest and by far the most common. What matters here isn't the brand but whether the model holds its rated output when it's below zero outside.
Floor console
Sits low against the wall and pushes warm air out at floor level. The answer in the low-stud cottages around Arrowtown and central Queenstown, and where a fire has come out and you want heat from roughly the same place.
Multi-split
Several indoor heads off one outdoor unit. On an exposed or snow-prone section that means one outdoor position to get right rather than three.
Ducted
Zoned whole-home heating hidden in the roof, so the living areas run by day and the bedrooms at night. It is cheapest to fit before the linings go up, which is why the new builds at Jack’s Point, Lake Hayes Estate and Hanley’s Farm specify it from the start.
What size heat pump do you need
One decision matters more than any other here, and it's not the brand. Heating output is almost always advertised at 7 degrees, and a unit's real capacity falls away as the air gets colder, so a model picked on that number can be well short on the mornings you actually need it. A cold-climate-rated unit holds close to its output down to around minus 15. Everything else is a detail beside that.
Bedroom or small room
About 2.5kW.
Standard living area
5 to 6kW.
Large or open-plan
7 to 8kW.
Undersizing is the common mistake here, not oversizing. A unit running at its limit never quite gets there on the coldest nights, and burns more power trying.
Three districts, three winters
In the Wakatipu, cold air drains off the ranges and pools on the valley floors, so Frankton and Lake Hayes sit in the coldest air in the basin on a still night. Over the Crown Range the Upper Clutha opens into a high inland basin running a true continental winter, and the flats at Albert Town and Hawea Flat are genuine frost pockets that get sized up as a matter of course.
East over the hills, the Central Otago basins at Cromwell, Alexandra and Clyde swing from hard frost to baking summer, so the same system has to do both jobs well.
An old cottage needs more than a new build
A single-glazed timber cottage in central Queenstown or Arrowtown loses heat through the walls and windows faster than the unit can put it back, and an exposed home catching the wind off the lake loses it faster again. The newer builds at Jack's Point, Hanley's Farm, Shotover Country and Quail Rise are insulated and double glazed, so they hold a temperature on far less.
The sizing calculator gives you a starting figure and your installer settles it on site.
Replacing an old heat pump
Ten years or more, struggling, or throwing error codes usually means a replacement makes better sense than a repair, because parts get scarce and efficiency has moved on. There is a local reason as well: plenty of the units fitted around the district a decade ago were standard models never rated for this climate, so they have spent every winter working at the edge of what they can do. Replacing like for like repeats the mistake.
Pipework and cabling can sometimes be reused where they're the right size and in good condition, which takes a chunk off the price, and that gets checked rather than assumed. Pipework contaminated with the old refrigerant gets replaced, because leaving it shortens the life of the new system. Taking the old unit away is part of the quote.
A replacement is also the chance to fix the outdoor position. If the old unit sat on the ground where snow banks against the wall, or somewhere meltwater pools underneath it, moving the new one onto brackets clear of all that will do more for the next ten winters than an extra kilowatt would.
Worth knowing up front: your installer services and repairs the systems they install, not other companies' work. If someone else fitted your current unit they will still come out, look at it and quote a replacement.
Consent and electrical work
A standard high-wall heat pump needs no building or resource consent. Ducted work that forms part of a new build or a major renovation is normally covered by the consent for that project rather than needing its own, and Queenstown Lakes District Council is the authority if anything about your situation is unusual.
The electrical work is carried out and certified by a registered electrician, and the refrigerant work by someone holding an approved filler licence, which is a legal requirement in New Zealand. Both are part of the install and the paperwork comes with it.
Two local situations are worth raising before anything is booked. The Arrowtown historic precinct has rules about what can appear on a visible elevation, and a large share of housing across the Lakes is apartments, body corporate or cross-lease, where the permitted outdoor unit positions may already be decided. Both are quote-stage conversations rather than install-day surprises.
Looking after your heat pump
Systems here are worked harder than in a mild climate. They run long hours through sub-zero winters and then switch to cooling through hot, dry summers with dust and pollen on the breeze, and that workload is why servicing matters more here than it does further north. A clean and a check every year or two keeps the output up and catches small problems before a cold snap turns them into an emergency.
Through winter, keep the outdoor unit clear: brush snow off the top and away from the sides, and make sure meltwater can drain away instead of pooling and freezing underneath it.
Some frost on the outdoor coil is normal, and the unit runs a defrost cycle to clear it. Heavy or constant icing isn't, and it usually points to one of three things: a position where snow builds up against the unit, a system low on refrigerant, or a unit that was undersized and is working too hard. Book a service if that sounds like yours.
Common questions about heat pump installation
How much does heat pump installation cost in Queenstown?
Fitted, a high-wall runs about $2,200 to $3,200 for a small room, $3,000 to $4,800 for a standard living area and $4,200 to $6,000 for a large or open-plan space. Multi-split systems are $5,500 to $14,500 depending on the number of rooms, and zoned ducted starts around $14,000. All include GST.
Do I really need a cold-climate model?
Yes, and it's the decision that matters most. Standard units are rated at 7 degrees and lose output as the air cools, so they fall short exactly when you need them. A cold-climate model holds close to its rated output to around minus 15 and defrosts less often.
Is Wanaka colder than Queenstown?
Often, yes. Wanaka sits in a high inland basin running a true continental winter, and the flats at Albert Town and Hawea Flat are genuine frost pockets that frost harder and earlier than the township. Homes there get sized up as a matter of course.
How long does the job take?
Three to five hours for a single high-wall, so you're warm the same day. A long stretch of pipework or an awkward wall can stretch that to a full day, and multi-split and ducted systems are planned in advance over a longer period.
Why is my outdoor unit icing up?
A little frost is normal and the defrost cycle clears it. Heavy or constant ice usually means the unit is sited where snow builds up against it, it's low on refrigerant, or it was undersized and is working too hard. It's worth looking at rather than living with.
Can you heat a whole house evenly?
That's what a zoned ducted system is for: living areas warm by day, bedrooms at night, no hot lounge and freezing hallway. It's far cheaper designed in before the linings go up than retrofitted, so it's worth raising early if you're building.
Do I need consent?
Not for a standard high-wall. The electrical work is certified as part of the install. The Arrowtown historic precinct and body corporate or cross-lease rules are the two things worth checking first, and Queenstown Lakes District Council is the authority on consent itself.
What does it cost to run?
A correctly sized unit heating a living area typically adds somewhere between $40 and $90 a month through the coldest part of winter, depending on the hours you run it and how well the house holds heat. Heat pumps return roughly three to four units of heat per unit of electricity, and a cold-climate model keeps that advantage below zero where a standard one loses it.
