Description
The MRCOOL VersaPro MPG36S090MO13C is a 3-ton (36,000 BTU) gas/electric package unit that combines R-454B air conditioning rated at 13.4 SEER2 / 11 EER2 with a 90,000 BTU, 81% AFUE natural gas furnace in one outdoor cabinet. Everything is factory assembled and charged, so a single unit on a pad or roof handles both cooling and heating for homes and light commercial spaces. The multi-position cabinet connects to horizontal or downflow duct runs, and an LP conversion kit is included for propane installations.
The MRCOOL® VersaPro® Series 36K 90,000 BTU Gas Package Unit delivers reliable, year-round comfort in one efficient, space-saving system. It combines a 13.4 SEER2 air conditioner with an 81% AFUE gas furnace, providing dependable cooling for hot summers and consistent heating through cold winters. This hybrid design is a cost-effective upgrade that improves comfort while helping lower monthly energy bills.
Environmentally conscious homeowners will appreciate the R-454B refrigerant, a next-generation formula with a much lower global warming potential than traditional refrigerants—delivering a greener solution without compromising performance. Built for long-term durability, the power-painted galvanized steel cabinet resists rust and weather damage, while the horizontal discharge design reduces operational noise—ideal for residential neighborhoods.
Inside, aluminum tubing with microchannel coils enhances heat transfer, provides better corrosion resistance than copper, and reduces maintenance while extending system life. High-efficiency compressors paired with an ECM blower motor ensure smooth, quiet performance, precise airflow, and consistent temperature regulation. Built-in safety controls monitor high/low pressure and coil temperature variations, protecting the system even under extreme conditions.
For installation flexibility, the VersaPro® 36K 90,000 BTU supports horizontal and downflow configurations. Its compact footprint fits where larger units cannot, and an LP conversion kit is included for propane use. When registered, it comes with a 10-year limited parts warranty and a lifetime heat exchanger warranty, providing lasting value, energy efficiency, and reliable all-season comfort.
