Side discharge/Horizontal Straight Cool Package Unit

A Package Unit Supply Return Plenum is an essential component in HVAC systems, responsible for distributing conditioned air from the package unit into your home and returning indoor air back to the system for recirculation. The supply plenum connects to the unit's output, directing cooled or heated air through the ductwork, while the return plenum ensures that stale air is drawn back into the system for filtration and reconditioning. Proper installation of supply and return plenums is crucial for optimal airflow and system efficiency. At acunitsforless.com, we offer high-quality plenums to complement your package unit and enhance indoor air circulation.

A Side Discharge/Horizontal Package Unit and a Downflow Unit differ primarily in how they direct airflow.

• Side Discharge/Horizontal Units release air from the side, making them ideal for homes or buildings where space is limited. These units are commonly used in areas with horizontal ductwork or where there’s limited vertical clearance. They are perfect for placement on rooftops or narrow exterior areas where vertical airflow is impractical.

• Downflow Units, on the other hand, discharge air downward, making them suitable for installations where the ductwork runs below the unit, such as in basements or attics. Downflow units are commonly used in homes with ducts that need direct downward airflow for efficient circulation.

Choosing between these two depends on the layout of your home and ductwork configuration. At acunitsforless.com, we offer both side discharge/horizontal and downflow units, ensuring you find the perfect system for your space and comfort needs
