Actual costs will depend on job size conditions and options.
Attic size for 1500 sq ft house.
So for instance a 1 500 square foot home would look something like this.
House square footage times 30 divided by 12 000 1 0 required tonnage.
So you would want to install a 3 5 ton unit.
The average cost per square foot is between 0 64 1 19.
Example 20 wide by 50 long attic.
So for a 500 square foot area your estimate will vary between 145 to 200 if you do it yourself.
