What size of central and heat unit do you need for 916 sq ft?
You take the size of your home in square feet and times it by how many rooms you have. A 70,000 BTU furnace will heat a house 1600 square feet.
Rule of thumb is 1.5 tons per 1000 square feet of home.
1,680 square feet.
A commonly used formula is 600-650 square feet per ton. So it would be recommended to use a 2-ton heat pump for a 1300 square foot home. However, other variables are often considered, too, such as the age of the house.
75,000 square feet
The rule of thumb is 2-1/2 tons per 1000 square feet.
14ft x 76 ft = 1064 square feet.
There's no way to calculate that just from square footage.
Depends on cubic feet too, not just square feet. High ceilings such as cathedrals and trays make a difference, as well as the number of windows. Another consideration is one story or two story. I always prefer separate zones for each story. That said, I would estimate 5 to 6 tons for 2700 square feet single story with normal window situation and standard ceilings. Minimum 13 SEER.
14 feet x 70 feet = 980 square feet.
There is not an average cost to buy a central heat and air unit. You will need to purchase a unit based on the square footage of your home, the amount of insulation in place and whether or not you have duct work in place. The price range starts at $1200 and goes up with size of your home.
32 x 70 = 2,240 square feet.
