MRCOOL VersaPro® 3.5 Ton 90,000 BTU Packaged A/C & Gas Unit (R-454B) — MPG42S090MO13C
Overview
The MRCOOL® VersaPro® MPG42S090MO13C is a packaged heating-and-cooling solution built for consistent performance and long service life. It pairs a 13.4 SEER2 A/C section with an 81% AFUE gas furnace, uses R-454B refrigerant, and is designed with a durable power-painted galvanized steel cabinet. A horizontal discharge layout helps reduce perceived outdoor noise, while the microchannel coil construction supports efficient heat transfer and corrosion resistance. The system’s ECM blower motor improves airflow control and comfort consistency.
Fuel type: Natural Gas / Propane (LP conversion kit included).
