Accurate calculations prevent:
Example 1: AC Tonnage for a 1,500 sq ft home (Hot Climate):
Example 2: Tile for a 10'x12' bathroom (10% waste):
Q: How do I adjust HVAC calculations for insulation quality?
A: Reduce BTU/sq ft by 5-10% for well-insulated homes; increase for poor insulation.
Q: What’s the difference between nominal and actual tile sizes?
A: Nominal includes grout gaps (e.g., 12"x12" tile may actually be 11.75"x11.75").
Q: Why add waste to flooring calculations?
A: Accounts for cuts, breaks, and pattern-matching (e.g., herringbone requires 15% waste).
Q: Can I calculate duct sizing with this tool?
A: No—duct sizing requires manual airflow (CFM) calculations based on room layout.
Q: How accurate are carpet estimates?
A: Depends on room shape. L-shaped rooms need more waste than square rooms.
Q: What’s the labor cost per sq ft for tile?
A: Typically \$4–\$8/sq ft (varies by tile type and subfloor prep).
Q: Do you include SEER ratings in AC calculations?
A: No—SEER affects efficiency, not tonnage. Use our Energy Cost Calculator for savings estimates.
