The size of air conditioner you need will depend on several factors, including the size of your home, the climate in your area, the number of windows in your home, the level of insulation, and the amount of shade around your home.
The cooling capacity of an air conditioner is measured in British Thermal Units (BTUs). As a general rule of thumb, you will need 20 BTUs per square foot of living space to effectively cool your home. However, this is just a rough estimate, and it’s always best to have a professional perform a load calculation to determine the exact size of air conditioner you need.
A load calculation takes into account all the factors mentioned earlier and is done by a licensed HVAC contractor. The contractor will assess your home’s size, layout, and insulation, as well as your family’s needs and preferences to determine the most appropriate size of air conditioner.
Installing an air conditioner that is too small will not effectively cool your home, while installing one that is too large can be inefficient and waste energy. It’s important to get the sizing right to ensure optimal performance and energy efficiency.
