A furnace fan is an electrically-powered device used in residential buildings for the purposes of circulating air through duct work. A furnace fan consists of a fan motor and its controls, an impeller, and a housing, typically as an assembly incorporated in a residential central heating, ventilation, and air conditioning (HVAC) product.

    After a regulatory action has been completed, Executive Order 12866 requires agencies to identify the substantive changes between the draft submitted to Office of Information and Regulatory Affairs (OIRA) for review and the action subsequently announced, and to identify those changes made at the suggestions or recommendation of OIRA.

    OIRA Compare Document (coming soon)

    DOE published a final rule to establish test procedures for measuring the electrical consumption for electrically-powered devices used in weatherized and non-weatherized gas, oil and electric furnaces and modular blowers to circulate air through ductwork. This final rule establishes procedures that will take effect on February 3, 2014. These procedures will be mandatory for product testing to demonstrate compliance with future energy standards and for representations starting 180 days after publication.
