Who must be a registered design professional in mechanical installations?

In mechanical installations, a registered design professional is essential because they possess the necessary qualifications and expertise to ensure that systems are designed and installed according to code, safety regulations, and industry standards. This designation often includes professional engineers or architects who have completed specific education and training, passed licensing exams, and maintained their credentials through continuing education. Their involvement ensures that mechanical systems are not only functional but also safe and efficient, supporting the overall integrity of building projects.

While other roles such as licensed contractors may be involved in the physical installation and maintenance of mechanical systems, they typically do not carry the responsibilities related to the design oversight required for compliance with building codes and regulations. Employees and maintenance workers, although they may have valuable skills, usually lack the formal designation and training necessary to take on the legal and technical responsibilities that come with being a registered design professional.
