The International Mechanical Code (IMC) is a set of regulations that governs the design, installation, and maintenance of mechanical systems in buildings. It aims to ensure safety, efficiency, and environmental protection in heating, ventilation, and air conditioning (HVAC) systems. The IMC is updated regularly to incorporate new technologies and practices. Developed by the International Code Council (ICC), the IMC is used by architects, engineers, and contractors to create compliant mechanical systems. It serves as a model code that can be adopted by local jurisdictions, helping to standardize building practices across different regions.
