Air conditioner size is measured in BTU or British Thermal Unit. BTU refers to the energy required to heat one pound or 0.45kg of water by one degree. Air conditioners measure the amount of air that can be heated or cooled by BTUs.

Several factors affect the amount of energy needed to heat or cool a room such as you determine which air conditioner size is the best for you.

  1. The area of the house.
  2. The number of floors in a building.
  3. The height of the ceilings.
  4. The number of people occupying or living in the area etc.

If the air conditioner unit is too large, it will shut off before dehumidifying an area and if it is too small, it will run constantly, costing you money without ever cooling or heating the room.

The common types of air conditioner sizes are the 12000 BTU, 18000 BTU and 24000 BTU. These sizes are commonly suited for your home and small office.

We’ve put together the list below to help you calculate the air conditioner size needed to heat or cool your home.

  1. 9-14 sqm = 5,000 BTU’s per hour.
  2. 14-23 sqm = 6,000 BTU’s per hour.
  3. 23-28 sqm = 7,000 BTU’s per hour.
  4. 28-33 sqm = 8,000 BTU’s per hour.
  5. 33-38 sqm = 9,000 BTU’s per hour.
  6. 38-43 sqm = 10,000 BTU’s per hour.
  7. 43-51 sqm = 12,000 BTU’s per hour.
  8. 38-43 sqm = 10,000 BTU’s per hour.
  9. 65-93 sqm = 18,000 BTU’s per hour.
  10. 130-139 sqm = 24,000 BTU’s per hour.
