What size unit do i need for my room?

  • Use the following chart to find the appropriate size air conditioner to use:
    AREA TO BE COOLED / CAPACITY (BTU/HR)

    [*]

  • 100 to 150 square feet = 5,000

    [*]

  • 150 to 250 square feet = 6,000

    [*]

  • 250 to 300 square feet = 7,000

    [*]

  • 300 to 350 square feet = 8,000

    [*]

  • 350 to 400 square feet = 9,000

    [*]

  • 400 to 450 square feet = 10,000

    [*]

  • 450 to 550 square feet = 12,000

    [*]

  • 550 to 700 square feet = 14,000

    [*]

  • 700 to 1000 square feet = 18,000

    [*]

If the room is heavily shaded, reduce needed capacity by 10%

If the room receives a lot of direct sun, increase needed capacity by10%

Add 600 Btu/Hr for each person in the room if there are more than two people

If the unit is for a kitchen, increase the capacity by 4,000-6,000 Btu/Hr.

Does the brand of air conditioner impact on how effectively they work within a given area? I assume that they are not all constructed in the same way i would imagine that some would be better for covering certain size areas or even areas that are shaped unusually?

brand doesn't impact how they cool. They all do the same basic function, pull air across a cold evaporator and blow it out into the room. Sure, some are probably better than others in some sense. The basic thing you look at is BTU rating and room size in square feet. Also consider if the outside of the unit will be in direct sunlight or not...etc.

They do offer specialty a/c units that don't sit in the window and blow the discharge air out a 4 inch duct. Pricey though.

Hey bro...If you don't know the answer to something, the stupidest thing to do is not ask. I wish I could turn the hands back and ask some questions myself. My pleasure to answer your question, difficult or not.
