Say goodbye to inconsistent temperatures in your home with the 3.5 Ton MRCOOL ProDirect Central Air Handler – Multiposition. Designed to handle areas between 1,750 to 2,100 square feet, this high-capacity air handler delivers powerful, reliable airflow with a SEER2 rating of up to 15. It features a 4-way convertible design for maximum installation flexibility—ideal for upflow, downflow, or horizontal configurations. The insulated galvanized steel cabinet comes with thermal insulator covers on each panel to reduce energy loss and prevent internal moisture buildup. For added protection and durability, the coils are guarded by a louvered steel shield.
This unit works seamlessly with the MRCOOL ProDirect condenser (sold separately), which includes Goldfin Corrosion Protection—an advanced nano-coating applied to coils for improved longevity. Built to support year-round performance, the system includes automatic defrost features, a removable air filter for easy maintenance, and compatibility with piston-style expansion devices. The internal components—like the multi-speed blower motor and direct-drive scroll compressor—ensure consistent and quiet climate control throughout your entire home.
