Manual J, S and D calculations, Test and Balance, and Blower and Duct Testing are vital to determining the heating and cooling loads for each room or zone within a building. HVAC professionals use these load calculations to select appropriately sized equipment, such as furnaces, air conditioners, heat pumps, and ductwork.
Overall, these calculations and tests help ensure that HVAC systems are sized correctly to meet the building's heating and cooling needs efficiently. Ensuring these calcuations leads to improved comfort, energy savings, and reduced operating costs over the life of the system.
