There are a lot of different factors that affect the sizing but the general formula is: Room Volume (L × W × H) × 185 + (People + Appliances) × 200 BTU/hr. For a standard 3 × 4 m bedroom with 2.7 m ceilings, a 9,000 BTU unit is usually sufficient. Refer to the calculator above for an accurate calculation on the unit size that will work best for your heating and cooling requirements!
