The software includes an HVAC part catalog that contains hundreds of parts in thousands of sizes. The part types range from large components, such as rooftop air conditioning units, to small components, such as grilles. For some HVAC parts, such as air terminals and VAV boxes, you can assign flow values; these values can be used to calculate duct sizes.
