Load Calculation Question.........
Observed a load calculation with software and it recommends a 1-ton system for a heat gain up to 15,000 btu's.
Recommends 1 1/2- ton system for heat gain up 21,000.
Why a 12,000 btu system for 15,000 Btu heat load?
Why a 18,000 btu system for 21,000 Btu heat load?
Thanks for any feedback?
