What type of systems does the International Mechanical Code apply to?

The International Mechanical Code specifically applies to permanently installed mechanical systems, which include a wide range of fixed installations designed to ensure the safe and efficient operation of heating, ventilation, air conditioning, refrigeration, and other related systems. This code establishes minimum regulations to safeguard life, health, property, and public welfare through proper design and maintenance of these systems.

Permanently installed mechanical systems are those that are built into or attached to the structure in such a way that they cannot be easily removed, making compliance with safety and efficiency standards crucial. This includes ductwork, water and gas piping, and installed HVAC units.

In contrast, standard HVAC systems, portable mechanical systems, and environmental systems might not encompass all the specifics required for compliance under the International Mechanical Code. For example, standard HVAC systems can refer to temporary or movable systems, while portable systems are meant to be easily relocated and not permanently installed. Environmental systems, on their own, do not encompass the full scope of mechanical installations required under the code.
