VersaPro 3.5 Ton 90K BTU Packaged A/C & Gas – R-454B – Downflow/Horizontal

The MRCOOL® VersaPro® Series 42K 90,000 BTU Gas Package Unit is an all-in-one heating and cooling system designed to provide consistent, year-round comfort. It combines a 13.4 SEER2 high-efficiency air conditioner with an 81% AFUE gas furnace, delivering reliable cooling during hot summer months and dependable warmth during the coldest winters. This hybrid design offers an effective upgrade that improves comfort while helping lower monthly energy costs.

The unit uses R-454B refrigerant, a next-generation formula with a much lower global warming potential than older refrigerants. This provides a more environmentally responsible solution without sacrificing performance.

Built for long-term durability, the power-painted galvanized steel cabinet protects against rust, weather damage, and wear, while the horizontal discharge configuration keeps operation quiet. Inside, aluminum tubing with microchannel coils maximizes heat transfer efficiency and provides superior corrosion resistance compared to copper, reducing maintenance needs over time.

High-efficiency compressors paired with an ECM blower motor ensure smooth, quiet, and consistent airflow. Integrated safety controls monitor high/low pressure and coil temperatures, helping maintain reliable operation even under demanding conditions.

For installation flexibility, the VersaPro® 42K supports horizontal and downflow configurations and features a compact footprint for tight spaces. An LP conversion kit is included for propane use, and a convenient access panel simplifies maintenance.

When registered, the unit comes with a 10-year limited parts warranty and a lifetime heat exchanger warranty, providing long-term reliability, efficiency, and peace of mind.
