✅ Full Product Description
The MAXAIR high-velocity hydronic air handler is a compact fan coil unit engineered for hydro-air heating using hot water supplied by a boiler. Designed for small-duct high-velocity HVAC systems, this air handler delivers efficient heating and cooling air distribution in homes where conventional ductwork is impractical or space-limited.
Unlike furnaces, MAXAIR hydronic air handlers do not generate heat directly. Heated water circulates through an internal coil connected to a boiler or hot-water heat source, and the blower distributes warm air through insulated small-diameter ducts. This configuration allows hydronic heating to be delivered through discreet duct outlets with minimal structural impact.
High-velocity hydronic air handlers are especially suitable for:
-
Older homes without duct space
-
Renovations and retrofits
-
Custom architectural homes
-
Boiler-based hydro-air systems
-
Combined boiler heating and AC cooling
-
Installations requiring minimal bulkheads
The FLEXAIR small-duct distribution system uses insulated 2½-inch supply ducts that fit inside standard wall cavities, reducing the need for soffits or major structural alterations. This makes high-velocity systems ideal for preserving interior finishes during HVAC upgrades.
MAXAIR high-velocity air handlers can integrate with central air conditioning or heat pump cooling by incorporating an evaporator coil, allowing one compact duct system to provide both hydronic heating and cooling. This approach is widely used in Ontario hydro-air HVAC designs for space-efficient comfort.
Bison Air installs MAXAIR high-velocity hydronic air handlers across Toronto and surrounding GTA communities including Markham, Richmond Hill, Vaughan, Aurora, Newmarket, and North York. Each installation is configured for proper boiler compatibility, airflow design, and small-duct distribution to ensure reliable hydro-air system performance.

✅ Installation & System Requirements
Hydronic air handlers require a boiler or compatible hot-water heat source and do not operate as standalone heaters.
Proper sizing depends on boiler capacity, airflow design, and small-duct layout.
Standard installation is included. Final installation scope may vary depending on electrical, duct routing, or structural conditions.
✅ Warranty
Parts: 1 year
Labor: 1 year (standard installation)
An optional extended 10-year labour warranty is available for $700, providing long-term installation coverage and service assurance.
