Mechanical Code refers to a set of regulations and standards that govern the design, installation, and maintenance of mechanical systems in buildings. These systems include heating, ventilation, air conditioning (HVAC), plumbing, and refrigeration. The code ensures that these systems operate safely and efficiently, protecting both occupants and the environment. The International Mechanical Code (IMC) is one of the most widely adopted codes in the United States. It provides guidelines for various aspects of mechanical systems, such as ductwork, equipment sizing, and energy efficiency. Compliance with the Mechanical Code is essential for obtaining building permits and ensuring public safety.
