We created a separate and distinct category for mobile home equipment because of the unique demands placed on cooling and heating systems used in these applications. The primary difference between a mobile home furnace and a furnace designed for a site-built home is the way the furnace is ducted, vented, and installed.

The ducting in a mobile home is smaller and therefore more restrictive, so the furnace blower must be designed to overcome the greater resistance to airflow. This ensures proper air delivery from each supply register. Standard furnaces will not provide the rated air delivery in a mobile home application.

Finally, the return air is drawn through a louvered grill on the front of the furnace, without the need for return ducting. The return air on a standard furnace is drawn from the top (or bottom) and must be ducted to a remote location. Standard furnaces from almost all other manufacturers are not designed or rated for use in mobile homes and can be unsafe if an attempt is made to use them improperly. All furnaces and equipment in this category are design-specific for use in mobile and manufactured homes.

The Coleman E.B. Series Electric Furnace for mobile and manufactured homes is actually two systems in one: As a powerful air handler they can handle up to 4 tons of air conditioning (3.5 tons when used with heat pumps).
