The MaxAir e LV Low Velocity Air Handler is a compact hydronic fan coil system designed for residential combination heating and cooling applications. Equipped with an energy-efficient ECM motor, it delivers consistent airflow, quiet operation, and integrates with boilers or water heaters for space heating while supporting DX cooling coils for year-round comfort.
The MaxAir e LV Low Velocity Air Handler is engineered for hydronic heating systems that combine domestic hot water production with whole-home comfort. Designed to operate with boilers or approved water heaters, these compact air handlers provide efficient heating while also accommodating direct expansion (DX) cooling coils for air conditioning.
Each unit features an electronically commutated motor (ECM), providing high efficiency, low electrical consumption, quieter operation, and continuous airflow capability. The ECM motor automatically adjusts to maintain consistent airflow, improving comfort while reducing operating costs.
The compact cabinet allows installation in basements, utility rooms, closets, crawl spaces, or attic applications where conventional furnaces are impractical. Multi-position installation flexibility makes these systems an excellent choice for new construction, renovations, and replacement projects.
Proper equipment sizing is essential for maximizing system efficiency and comfort. Heating capacity must be matched to the home's heat loss, while airflow requirements must correspond with the duct system and optional cooling coil selection. Our design process ensures your air handler is correctly sized for both heating and cooling performance.
Professional installation also includes proper hydronic piping, electrical connections, condensate drainage, airflow balancing, and commissioning. Correct venting and piping arrangements for the connected boiler or water heater are equally important to ensure safe, reliable long-term operation.
At 4Most Energy, every installation is completed according to manufacturer recommendations and local building codes to provide dependable comfort for years to come.
