When shopping around for an air conditioner for your property, it is important to make the right decision. Different units offer different cooling capacities. A unit with too much cooling capacity will be expensive and inefficient to operate. A unit with insufficient capacity won’t be able to get the job done and will provide you with unending frustrations. There is also a surprisingly close relation between dehumidifying the air and the unit’s cooling capacity.


An over-sized air conditioner will quickly cool the air, without running long enough to dehumidify the air. This will lead to the detested “cold, clammy” atmosphere that no one wants. How do you determine the level of cooling capacity that your eventual unit should have? This is determined in most part by the type of construction of your property, as well as the geographical location of your home.


Here are a few tips on how to choose the right air conditioner for your home. Start by measuring the square footage of the room that the air conditioner will be operating in. After this, calculate the cooling capacity that you’ll need from your unit. Natural Resources Canada, Energy Star website offers guidelines for BTUs per square footage such as:


  • 1000 BTU up to 300 sq. feet
  • 5,000 to 7,000 BTU from 300 up to 550 sq. feet
  • 8,000 to 12,000 BTU from 550 up to 1,000 sq. feet
  • 14,000 to 18,000 BTU from 1,000 up to 1,200 sq. feet
  • 21,000 to 24,000 BTU 1,500 up to 2,000 sq. feet
