A major trend we have noticed at OneAir over the last few years is that more people than ever before are using their heat pumps for cooling and not just for winter heating. This is especially the case for two-storey homes, where the upper floors - especially bedrooms - get extremely hot on sunny days and modern homes which are more air tight and trap heat better than older homes with lots of air gaps used to do.
The good news is that heat pumps or conditioners, more commonly known as heat pumps in NZ, have become a staple in Kiwihomes, offering a haven from sweltering summer days and of course serving as heating solutions during winters. While some use their heat pumps only for heating in winter, more NZers are turning the mode button to “cool” than ever before, due to a combination of rising summer temperatures, greater awareness of - and appreciation for - the air conditioning feature or a combination of both. This comprehensive buyer's guide will help you navigate the complexities of choosing, owning, and maintaining an air conditioner, ensuring you make a decision that suits your needs and budget.
Using the Air conditioning systems is no longer considered a luxury, but a practical necessity for many homeowners, especially elderly residents for whom oppressive heat can present significant comfort and even health concerns. With rising temperatures during summer and the need for efficient heating in winter, air conditioners cater to year-round comfort. However, making an informed choice requires understanding the options, costs, and maintenance involved. This guide will break down everything you need to know about air conditioners in New Zealand, explicitly tailored to our unique climate and lifestyle.
Before discussing specific types and features, let's review the overall advantages and potential drawbacks of owning an air conditioner.

Features to Look for When Buying an Air Conditioner in New Zealand
There are hundreds of different heat pump models for sale in NZ, each with their own specific features and performance abilities. These features can make a significant difference to your home comfort, experience and even family health, so a careful consideration of your requirements and preferences is essential if you want to be happy with your choice in the long term. Based upon our years of experience dealing with thousands of heat pumps all across NZ, we have listed the below summary of the most-important features we hear mentioned most by our customers.
Must Haves:
High Energy Efficiency Rating (EER) / Low power consumption:
Like a car’s km/L fuel consumption figure, the higher this number is, the better, and small heat pumps generally have a higher efficiency than larger heat pumps. Unlike a car though, heat pumps have different efficiency ratings depending upon whether they are operating in heating or cooling mode. EER is the measure of how efficient a heat pump is at creating cool air. For small heat pump units below 5kW, look for an EER of 4.0 or higher EER. while for larger 5kW and above models look for EER figures of 3.5 or more
TIP: Be careful when comparing ENERGY STAR stickers as heat pumps imported to NZ before 1 July 2021 will have the old ERL energy rating labels compared to those imported after this date which use the new ZERL standard.
Correct size / Capacity:
Measured in kilowatts (kW), generally speaking a 2.5kW system is suitable for small rooms, while larger spaces like family living rooms require 5 kW or more. There are however lots of variables in this calculation, including insulation levels and how much glass the room has that is in direct sunlight for long periods. Other factors influencing sizing are what part of NZ you are in, how cold your winters get and if a Healthy Homes formula for rental properties has been applied. Ask an experienced installer [link to relevant article] to explain what variables he has identified and how he has adjusted his sizing formula to accommodate them.
Noise Levels
Opt for models with an indoor unit noise rating below 30 decibels for quiet operation, 25dB or less if inside a bedroom
Location in NZ
Warranty and Support:
Ensure the unit comes with a comprehensive warranty and reliable customer support.
Nice to Haves:
WIFI : allows more options to control your air conditioning system
Quiet mode : some models have this available for indoor and outdoor units
Front digital temperature display: instant readout of the temperature set point allows you to quickly see if it is running and helps decisions regarding s temperature adjustments
Draught-free mode : while some people may enjoy the feeling of a strong, cool breeze blowing at them, others may wish to avoid this sensation, especially when sitting down to eat dinner or watching TV.
