How To Calculate The Air Conditioner Size For Your Whole House
To calculate the ideal ducted aircon size for your house, follow these simple steps:
- A rough calculation of the size of your DAYTIME living areas – kitchens, family rooms, lounges, media, study, entrances, hallways, stairs.
*Bedrooms aren’t used as much during the day
- Multiply the size of your daytime living areas by ceiling height. High ceilings require more air to cool.
This rough calculation can be affected by a number of factors, including insulation or large windows. Mention this calculation when you speak with one of our experts.
