This manual supersedes Forced-Circulation Air-Cooling and Air-Heating Coils Operations Manual, January 2012.

AHRI provides independent verification of ACHC manufacturers’ stated equipment performance.

AHRI shall compare the ratings with the results obtained through use of the Participant’s Selection Rating Software.  Comparison shall only be made on jobs in which the Selection Rating Software implemented by the user matches that of the verified rating method, including issue date or code, of the current software held by AHRI. All certified product information, including current Selection Rating Software version, is shown in the AHRI Directory.
