What is the recommended location for a cooling coil on a suspended or horizontal furnace?

The recommended location for a cooling coil on a suspended or horizontal furnace is on the supply air side. Placing the cooling coil in this position allows for better management of air temperature as it directly impacts the conditioned air being distributed into the space. When the cooling coil is located on the supply side, it effectively cools the air before it reaches the living or working areas, ensuring a comfortable environment.

This orientation also helps in reducing the load on the furnace itself, as the cooled air enters the space at a lower temperature, maintaining efficiency and performance. Furthermore, placing the cooling coil on the supply air side minimizes the potential for moisture accumulation on the cooler surfaces, which can be a concern when cooling air that has already been conditioned. Overall, positioning the cooling coil on the supply side optimizes the heating and cooling dynamic of the entire system, enhancing overall comfort and efficiency.
