05/11/2026 Commercial Mechanical Express REQUIRES RESUBMIT Replacement of commercial AC units constitutes new work so the submittal will require a heating/cooling load calculation to justify the capacities of the units being installed (Section C403.3.1, IECC 2018). While ventilation calculations are not required, a test and balance report is required to verify that the total supply airflow and the outside airflow are at least equal to that which the previous AC unit provided. Reference: Section C503.3, IECC 2018.
Note: New heating /cooling loads are not required for emergency replacement of cooling and heating equipment where there are no alterations, additions, or changes of occupancy, the equipment does not increase in capacity, and the equipment was installed prior to January 1, 2013
