Equipment Sizing shall be verified by the following:

Heating and cooling equipment shall be sized in accordance with ACCA Manual S based on building loads calculated in accordance with ACCA Manual J. 

One of the most important sections of this code to the HVAC contractor is Duct Sealing.

 Duct Sealing shall be verified by either of the following:

1. Post-construction test: Leakage to outdoors shall be less than or equal to 12 CFM per 100 square feet of conditioned floor area when tested at a pressure differential of 0.1 inches w.g. (25 Pa) across the entire system, including the manufacturer's air handler enclosure. All register boots shall be taped or otherwise sealed during the test.

2. Rough-in test: Total leakage shall be less than or equal to 12 CFM per 100 square feet of conditioned floor area when tested at a pressure differential of 0.1 inches w.g. (25 Pa) across the roughed in system, including the manufacturer's air handler enclosure. All register boots shall be taped or otherwise sealed during the test.  If the air handler is not installed at the time of the test, total leakage shall be less than or equal to 12 CFM per 100 square feet of conditioned floor area.

 Exceptions: Duct tightness test is not required if the air handler and all ducts are located within conditioned space.

 Metro requires that the duct tightness performance testing for residential new construction must be performed by a certified third-party contractor.
