Manual S® - Residential Equipment Selection (2nd Edition)

Manual S® - Residential Equipment Selection (2nd Edition)

The Manual S® - Residential Equipment Selection (2nd Edition) from 1 Exam Prep is an official ACCA publication required for DBPR and CILB HVAC-related contractor license examinations in Florida. This manual provides detailed procedures for selecting residential heating and cooling equipment that complies with load calculations established in ACCA Manual J®. It includes methodologies for matching air conditioners, heat pumps, and furnaces to system design requirements, factoring in airflow, duct sizing, latent and sensible load, and manufacturer performance data. Recognized in PSI-administered Air A, Air B, and Mechanical Contractor exams, this reference ensures contractors meet Florida Building Code – Energy Conservation and ASHRAE performance standards for efficient, code-compliant HVAC system design and installation.


Manual S shows you how to select and size heating and cooling equipment to meet loads for a particular home, which are based on local climate and home construction specifics. Contractors in Miami, Phoenix, and Seattle - all extremely different climates - would never use the same equipment and expect the same results. Manual S provides sizing requirements for 11 types of cooling and heating equipment, as well as in-depth explanations and examples of how to use manufacturer's performance data. New for this edition: Contains new sizing rules that recognize multi- and variable speed equipment with larger over sizing limits. Covers 11 types of equipment (previous version covered only four). Heat pumps in heating dominated locations have an optional over-sizing procedure. There are an increased number of example problems for Manual S procedures, as well as explanations of details/nuances (for contractors and educators). The book is reformatted so the first sections contain mandatory code official language.
