What is the best size window air conditioner to put in a living room?

Question

It is probably a medium size living room. Don't have a lot of money to fix our big unit so we have to get little units. Anyone got good advice about what type of btu or size to buy for medium sized living room?

Answer 1

400-700 square feet per 12,000 BTU

It depends on how hot it gets in your area of the world and how big the room is.

A 20x20 room say in texas may need a 12000 BTU,  and in Minnesota the same area can be cooled with a 9000 BTU.  

Answer 2

You need to know the sq footage of the room then buy the btu that corresponds with that footage

Answer 3

measure the lenght and width of the room, and multiply to get square feet,, take that number and go where you are going to buy the unit...buy aunit that is larger than that number...

boxes will be marked " cools a 12 x 12 room" or " cools  144 square feet:
