What is the maximum capacity of a mini-split heat pump that a Journeyman Technician may install in a one or two-family dwelling?

A Journeyman Technician is permitted to install mini-split heat pumps with a maximum capacity of 36,000 BTUs in one or two-family dwellings. This capacity limit is established to ensure that technicians are working within a framework that promotes safety, efficiency, and compliance with local codes and regulations.

Mini-split heat pumps are versatile heating and cooling systems commonly used in residential applications, especially in homes where ductwork may not be feasible. The 36,000 BTU limit allows technicians to adequately serve the heating and cooling needs of a typical home while ensuring they possess the necessary skills and knowledge to operate these systems safely.

Understanding this capacity limit is crucial because it dictates the scope of work that a Journeyman Technician is authorized to perform. Exceeding this capacity would require additional training, certification, or a different classification of license, reinforcing the importance of adhering to the specified guidelines within the Maine Fuel Code.
