Ducted Air Handler
High-efficiency whole-home air conditioning — hydronic, silent, intelligent
The Messana ducted air handler is a high-efficiency chilled water fan coil engineered for whole-home comfort. Available in four sizes from 1.5 to 5.0 tons, with a variable-speed ECM motor, fully insulated galvanized steel cabinet, and three-way airflow flexibility — designed to integrate seamlessly with any Messana hydronic system.
The ECM advantage
Variable speed. Constant comfort.
At the heart of the air handler is a variable-speed ECM motor — a technology that transforms how a ducted system feels, sounds, and consumes energy. It is the reason this unit earns its place in the Silent Air ecosystem.
Three airflow positions
The air handler is field-convertible between three airflow configurations — adapting to the mechanical room layout, duct routing, and available space without requiring a different unit.
Build quality
Engineered for the long term
Every component of the air handler is specified for durability, efficiency, and quiet operation — from the galvanized steel cabinet to the copper-aluminum coil and corrosion-resistant drain pan.
Why choose Air Handler for your project:
When attic or crawlspace access exists, a single ducted air handler is the most cost-effective way to condition an entire floor or the whole house — one unit, one hydronic connection, one central coil that cools, heats, and dehumidifies up to 5 tons across every room, at a lower installed cost than running individual fan coils in each space.
