Product Description
The 2024 International Mechanical Code (IMC) is the International Code Council’s current code for HVAC and mechanical systems, available here in the ICC paperback edition for contractors, inspectors, and engineers.
The IMC governs heating, ventilating, air-conditioning, exhaust, duct, chimney, refrigeration, and boiler installations in buildings covered by the International Building Code. It is written with both prescriptive and performance provisions, so new materials and methods can be approved on their merits. The 2024 edition is the newest in the three-year I-Code cycle and shares the redesigned page layout introduced across the 2024 family.
What's included
- 2024 International Mechanical Code, complete text, paperback
- Publisher: International Code Council (ICC)
- Single-column format, QR codes marking changed sections, shaded tables placed with their parent text
- Authenticity validation and ICC book registration
Who it's for
HVAC and mechanical contractors working under the 2024 I-Codes, mechanical inspectors and plan reviewers, and mechanical engineers detailing ventilation, exhaust, and refrigeration systems. Candidates for state mechanical contractor licenses and ICC certification exams that reference the 2024 IMC should use this edition, and trade school instructors teaching commercial HVAC code will want it as the class text.
Why this edition
Each IMC cycle tracks changes in refrigerants, ventilation rates, and energy-related equipment, and 2024 continues that work alongside the companion International Energy Conservation Code. The practical improvement most users notice first is the new layout: one column of modern type, tables beside the sections that cite them, and QR codes that point to the changes from 2021. Adoption varies by state, so confirm whether your jurisdiction enforces 2021 or 2024 before buying for an inspection; for exams, use whichever edition the candidate bulletin names.
Frequently asked questions
Is the 2024 IMC the current International Mechanical Code?
Yes. The 2024 edition is the latest, following the 2021 and 2018 editions on ICC’s three-year cycle.
Does the IMC cover residential HVAC?
Detached one- and two-family dwellings usually fall under the International Residential Code instead. The IMC applies to commercial and larger residential buildings.
Does the IMC include fuel gas piping?
No. Gas piping and appliances are covered by the International Fuel Gas Code, a separate ICC book.
