The Uniform Mechanical Code (UMC) is a set of regulations that provides guidelines for the installation, maintenance, and inspection of mechanical systems in buildings. It covers various aspects, including heating, ventilation, air conditioning, and refrigeration systems, ensuring they operate safely and efficiently. The UMC is designed to protect public health and safety while promoting energy efficiency. Developed by the International Association of Plumbing and Mechanical Officials (IAPMO), the UMC is updated regularly to reflect advancements in technology and changes in industry practices. It serves as a model code that local jurisdictions can adopt or modify to suit their specific needs, helping to standardize mechanical practices across different regions.
