Most Open Plan Homes Need More Capacity Than Expected
Open-plan areas often include kitchens, dining rooms and living spaces. Combined with large windows and Perth summers, these spaces typically require larger systems than homeowners initially expect.
Why Open Plan Spaces Are Harder To Cool
Connected Spaces
Conditioned air can move freely throughout the home.
Kitchen Heat
Cooking appliances create additional heat loads.
Large Windows
Glass can dramatically increase cooling requirements.
Higher Ceilings
More air volume requires greater capacity.
More Occupants
Shared spaces often have higher occupancy levels.
Voids & Stairwells
Air naturally moves between levels.
