When it comes to choosing the perfect heat pump / air conditioning system for your home, there is no one-size-fits-all solution. Purchasing an oversized unit that blasts arctic-level cooling into an apartment-sized space can be inefficient, and a single unit situated in the middle of a five-bedroom house occupied by a family unfortunately will not keep the whole home comfortable.

All homes and families are different, with unique needs and requirements. A heat pump / air conditioner properly suited to the space will ensure your unit works as efficiently and effectively as possible. To find the perfect fit, it’s important to consider critical factors such as size, layout, occupant habits and sun orientation, to name just a few. 

Here are a few considerations before selecting your heat pump / air conditioning unit: 

  • Calculate the size of your home. Before going to a Fujitsu Accredited Installer, knowing how many rooms require heating or cooling and the size of each room is important, as this determines how powerful a heat pump / air conditioning system needs to be to effectively control the temperature in the space. There are several reasons why one type of heat pump / air conditioner may be a better fit for your home. Smaller homes and apartments may best suit one or two split system units. For larger homes, if there are more than two rooms to heat or cool, a multi-system might be best. If you are looking for a whole home comfort solution and have sufficient ceiling space, a whole home ducted system could be more suitable. 
  • Factor in insulation. Insulation plays a significant role in determining the right heat pump / air conditioning system for a home. Homes with better insulation retain cool and warm air better, reducing the workload of the heat pump / air conditioning system. Homes with poor insulation may require a more powerful heat pump / air conditioning system to effectively cool the space. A Fujitsu Accredited Installer will consider insulation when helping you determine the best solution, factoring in the amount of insulation in the walls and ceilings, as well as other factors such as square footage, the number of rooms, local climate, and the number and size of windows. 
  • Ceiling height and space. Ceiling height and space affect the volume of air that needs to be cooled. Taller ceilings require more cooling power to cool the same amount of space as a home with lower ceilings. Additionally, open floor plans with high ceilings can also result in a larger volume of air that needs to be cooled. A Fujitsu Accredited Installer can perform a load calculation and determine the correct system size for your home based on all relevant factors, including ceiling height and space. 
  • Which direction your home is facing relative to the sun. Homes facing north or south can receive more direct sunlight and therefore requires more cooling power. Homes that face east or west are typically more protected from direct sunlight and may require less cooling power.  


Request a heat load assessment  

A heat load assessment is an important component of the quote process conducted by a heat pump / air conditioning specialist. This is to ensure the correct size and type of heat pump / air conditioning system is specified and installed, providing you with the most efficient solution. New residential heat pump / air conditioning standards ensure specialists are adhering to these requests.
