Carrier is one of the oldest names in air conditioning. Willis Carrier invented modern air conditioning in 1902, and the badge has been on walls ever since.
In New Zealand, Carrier heat pumps come through AHI Carrier, the sole distributor of Carrier and Toshiba air conditioning here since 1998. It has support centres in Auckland and Christchurch, and branches in Wellington, Napier, New Plymouth and Dunedin.
Which Carrier heat pumps can you buy in New Zealand?
Allure Plus is the main wall unit. It runs from 2.0 to 8.0 kW of cooling, comes with wi-fi built in, has a UV lamp inside to stop bacteria and mould building up, and the outdoor unit cleans itself.
Ambi and Ambi Fabric are the newest wall units. Ambi Fabric has a textured fabric finish for rooms where a plain white box would look out of place. Both use a smart energy-saving mode that learns how you use the heat pump, run as quietly as 18 dB on the quiet setting, and come with a detachable Bluetooth controller that mounts on the wall with no wiring. The Carrier app also shows how much power the unit uses by the day, week or month.
The bi-flow floor console blows air from the top and the bottom, in two sizes with 4.2 and 5.3 kW of heating. Its quietest setting is about 21 dB, which suits a bedroom. Our floor console guide covers where one makes sense.
Multi-splits run three to six rooms off one outdoor unit. Indoor options include Allure Plus wall units, compact ceiling cassettes and bulkhead units hidden in a ceiling box.
For whole-house heating, Carrier’s Xpower ducted systems pair with the Comfort Zone controller. It’s a 7-inch touchscreen that splits the house into up to eight zones, or 16 with a second controller, each with its own temperature in half-degree steps.
There’s also the Carrier Blue hot water heat pump, an all-in-one unit in 190 and 300 litre sizes with built-in frost protection. Our guides on single-room vs multi-room and hot water heat pumps help you choose.

Does Carrier make a heat pump for cold climates?
There’s no separate cold-climate model in the Carrier line-up here. The Allure Plus, multi-splits and floor console all list a heating range down to minus 15°C outside, which covers a frosty Canterbury or Central Otago morning.
Output drops as it gets colder, so make sure the quote is sized for your coldest weeks, not an average one. Our guide on what size heat pump you need shows how.
Will a Carrier last near the sea?
Carrier outdoor units have a Golden Fin coating on the coil to slow rust, which helps in seaside towns from Ōrewa to Ōamaru. The Ambi adds corrosion treatment on the coil ends too.
The warranty itself doesn’t cover weathering or corrosion, though, and it expects you to add extra protection in sea air, near industry or in sulphur zones like Rotorua. Ask about it at quote time if you live on the coast.
How long is the Carrier warranty in New Zealand?
Carrier heat pumps supplied by AHI Carrier from 1 June 2025 and installed in New Zealand homes carry ten years:
- Years 1 to 5: parts and approved labour.
- Years 6 to 10: parts only, and you pay the technician’s time.
It covers high-walls, ducted systems, floor consoles and multi-splits. Carrier Blue hot water and Aquasnap units get five years parts and labour instead.
The ten years only count if the installer registers the system. The form records each unit’s model and serial number, the install date, a leak test and refrigerant check, heating and cooling readings, and the electrical Certificate of Compliance. The installer also declares the job followed the manufacturer’s guidelines. Ask for your warranty number before they leave.
The cover stays with you and the address where it was installed. It doesn’t pass to a new owner, and it doesn’t cover a unit moved to another house, poor installation, power supply faults, storm or vermin damage, or filters and batteries.

How to read a Carrier model number
Carrier model numbers come in a set of three. On an Allure Plus, the indoor unit starts with 42 (42QHG035N8-1), the outdoor unit with 38 (38QHG035N8) and the system as a whole with 53 (53QHG035-1).
The letters after that mark the range, and the three digits give the cooling size: 020 is 2.0 kW, 035 is 3.5 kW and 080 is 8.0 kW. Multi-split outdoor units start with 38QUM.
Write down both the indoor and outdoor codes and their serial numbers. You need them for the warranty form and for any service call.
Can you control a Carrier heat pump from your phone?
Carrier heat pumps have wi-fi built in, so you don’t need an add-on. Everything runs through Carrier’s Smart Home app, which can control all your Carrier units from one phone. Our guide to smart heat pumps covers timers and scheduling.
What Carrier error codes mean
On the Allure Plus, a Smart Diagnosis check in the app tests 97 functions and shows an EC code when it finds a problem. You can also run a self-check from the app to see whether the unit needs maintenance.
If the system detects a refrigerant leak, it stops by itself and shows the error on the indoor unit, the controller and the app. Don’t keep restarting it. Call a technician, because a leak needs a qualified person to find and fix.
Carrier multi-split outdoor units have a check point button and a status display that shows error codes, which helps a technician find the fault faster. For other symptoms, our heat pump problems guide covers the checks to try first.
Who do you call when a Carrier needs a service or repair?
Ring the installer first. Warranty work is done in normal business hours by AHI Carrier or a repair agent it authorises.
If your installer has gone, call AHI Carrier customer service on 09 355 6720 with your warranty number, model and serial numbers. Keep the filters clean, the outdoor unit clear and the drain flowing, because the warranty lists all three as your job. Our servicing guide has the full routine.
Of the 1,020 installer websites checked in October 2026, 55 mention Carrier.
