1500 sq ft.
36000 Btu
12000 btu = 1 ton 1 ton per 400 sq ft 1200 / 400 = 3 3 times 12000 = 36000 btu
700 to 1000
around 400 SF, not ft
24,000 btu's
2180 SqFt/500 = 4.4 tons of AC required x12000 BTU/ton = 52800 BTU's Answer is it takes 52800 BTU's to cool a 2180 SqFt home
600 BTU/ ft is what i have been told.
18,000-21,000 BTU's
One Small room "144 Sq ft"
5280 ft = 1 mile ⇒ 36000 ft = 36000 ÷ 5280 ft = 69/11 miles ≈ 6.82 miles
Too many variables as to R-factor in ceilings and walls and windows. The direct sun exposure. How many times per hour doors are opened, etc. But, with a ceiling height of 8 feet, roughly i ton (12,000 btu) will cool 600 sq. ft. Therefore, 25,000 is generally good for up to 1100-1200 sq. ft.
