The MRCOOL MGM96EE080B3NB-O is a high-efficiency residential natural gas furnace engineered to deliver improved comfort and energy performance. With an 80,000 BTU input capacity and a 96% AFUE rating, this condensing furnace maximizes heat extraction from combustion gases to reduce fuel consumption.
This two-stage furnace operates at a lower heating output during moderate conditions and increases to full capacity during peak demand. Two-stage performance enhances indoor temperature consistency, reduces short cycling, and supports improved overall comfort.
Designed for upflow or horizontal installation, this unit provides flexibility depending on mechanical space and duct configuration. As a 96% AFUE condensing furnace, it utilizes PVC venting and must be installed in accordance with local building and fuel gas codes.
Professional installation by a licensed HVAC technician is required to ensure proper sizing, airflow calibration, venting setup, and code compliance.
