The Lennox 21N39 Scale Insert offers an energy-efficient way to add air conditioning comfort to rooms in your home. It's made to fit Lennox air conditioners with a removable, electric-resistance heating element, like the Lennox 21N20 and the Lennox 21N21. The maximum capacity is 19,000 Btu.

Easily integrated into the Lennox® 21N39 central air conditioning system, the unique design of this scale insert eliminates the need for ducting and reduces installation time. Its innovative patent-pending filter capture mechanism prevents air from entering the return plenum without first passing through the filter. This helps protect HVAC equipment and increases air quality in your home.
