Electric duct furnaces must be tested in accordance with which standard?

Electric duct furnaces must be tested in accordance with UL 1995, which covers the safety requirements for heat pumps, air conditioners, and similar equipment. This standard specifically addresses electric heating appliances that are integral to the HVAC systems, ensuring they operate safely and effectively. It outlines criteria for the design, construction, performance, and testing of such units, thereby promoting safety and efficiency in their operation within mechanical systems.

The provisions of UL 1995 are crucial for ensuring that electric duct furnaces do not pose risks to users or property and meet baseline performance standards that reflect industry practices. Adhering to this standard helps manufacturers and installers provide reliable heating solutions that comply with regulatory expectations, thus contributing to safe building environments.
