ARLINGTON, Va. — The Air Conditioning Contractors of America Educational Institute (ACCA-EI) Standards Task Team (STT) is seeking public review of BSR/ACCA 3 Manual S – 201x, Residential Equipment Selection, as a revised and re-designated industry standard. The comment deadline is June 24.

This revised standard provides procedures for selecting and sizing residential comfort cooling and heating equipment. The standard has been divided into two parts — a normative portion that details the selection/sizing criteria and an informative portion that provides discussion, guidance, and example problems related to procedure intent and use.

A review version of the proposed second edition of Manual S (dated April 17), and the public review response form, can be downloaded at
