How to Choose the Right Heating and Cooling Solution for your Unique Space

3 April 2020

Heat Pump Air Conditioning Systems are a hugely popular method of heating in New Zealand, but they are also an increasingly popular solution for cooling your home over the Summer months. 


Whether you are installing a Heat Pump for the first time or looking to update your current heating and cooling system, you will need to know what your options are for effective and efficient climate control.


What is the best solution for your unique space? Let’s have a look at the factors you will need to consider before making your home comfort choice.



Choosing the right type and size of Heat Pump Air Conditioning System for your needs


The size of your room or the area you wish to condition will be a key indicator for the type, capacity size and power you will need. The larger the area the higher the Heat Pump capacity required. 

The one that’s just right for you depends on how big or small your space is and the number of rooms you wish to condition and many other factors.


If you have a Heat Pump installed that is too small, it may struggle to keep the room at the required temperature and will use more energy to do so. Too large, and the heat pump will need to cycle on and off to keep the temperature in the desired range. 

The most popular and cost-effective solution is the ‘High-Wall Split’ Heat Pump Air Conditioning system. These systems are a one-room heating and cooling solution and have a single outdoor unit connected to one indoor unit. 


The warm or cool air produced by a High-Wall Split Heat Pump Air Conditioner is only focused in the room that houses the indoor unit. On one hand, this means they can be used quite efficiently, only heating or cooling the room that you will be using. However, this also means that you may not be able to control the temperature in all of your rooms, leaving some parts of the house cooler in the winter and warmer in the Summer. 


For whole-home comfort, a ‘Ducted Heating and Cooling System’ may be the right solution. Ducted heating and cooling systems supply warm or cool air into every room in the house through ducts, usually located in the roof space or beneath the house. 


Ducted heating & cooling systems are generally a great option for people who prefer a discreet heating and cooling solution and would like to control the temperature of an entire house. 


There are many variables that need to be considered for an effective and efficient comfort solution for your unique space. Some factors to consider when choosing a heating and cooling solution for your home include your location within New Zealand and your home’s aspect, your budget, insulation, windows and ceiling height. 



Location and Aspect:  Outdoor conditions will affect your home heating and cooling selection. Some areas in New Zealand experience sub-zero temperatures which require larger Heat Pump air Conditioners than in more temperate regions. Queenstown and Auckland have quite different requirements, so appropriate unit selection is important. The sun is our most valuable (and free) source of heat, and it can really affect the temperature inside a room with heat transfer through walls and windows. Considering the influence of the sun, rooms that are facing east or west may need a different capacity Heat Pump compared to a north-facing room.


Windows: A room that has plenty of windows can be draughty as well as allowing heat and cold to enter or escape quickly. The size of your windows and insulating properties of the glass will have a greater effect on the size of the Heat Pump Air Conditioner than the walls and ceilings of the room. Having larger windows in a room may mean a larger capacity system is required because the room is less insulated.


Insulation: A well-insulated room needs less heating to maintain a comfortable temperature. The better the insulation in the walls and ceiling of the room, the lower the Heat Pump capacity required.


Budget: A heating and cooling solution for your home can be a big investment and price is something to be considered. A perfect home-comfort solution though is a great asset to any home enhancing the way you live in your unique space.



With all these factors to consider in choosing the right heating and cooling solution for your space, finding a qualified and accredited installer is imperative. A Heat Pump Air Conditioning expert can tell you exactly what type and size solution will be right for you and your family, no matter the weather!
