Understanding Right Air Conditioner Size

Proper sizing is the foundation of effective air conditioner system. Incorrect size of the unit may lead to inefficiency, increased energy cost and of course discomfort.

Calculate BTU Requirement

  • Measure The Square Footage of the Room

  • Multiply The Square Footage by 20 BTU Per Square Foot

  • Consider The Factors Like Ceiling Height, Sunlight Exposure and Occupancy.

For a 400 sq. ft. room you will need at least 8,000 BTU unit (400 x 20 = 8000).

Consider Room Size

While square footage is a primary factor other characteristics may also influence air conditioner choice like:

  • Ceiling Height: Higher celling may need more cooling power

  • Window Placement: South Facing Window Can Increase the Heat

  • Insulation Quality: Well-insulated room may retain cool air better

  • Room Purpose: Kitchen and Exercise Room Generates More Heat
