Evaporator coils are used in conjunction with split air conditioner systems - with or without heat pumps. The Goodman CAPF series evaporator coils are cased coils and feature a flowrater valve. This type of valve has a fixed orifice and is constructed to deliver a fixed amount of refrigerant to the coil, regardless of conditions. Evaporator coils are for use split system air conditioner condensers as well as heat pump systems. As noted in the item code, it can be used with two different tonnages. The CAPF3743D6 can be used with 36,000 (3 ton) or 42,000 BTU (3.5 ton) systems. The flowrater/orifice is for use with the larger tonnage - in this instance 3.5 tons. For use with a 3 ton system a different orifice/flowrater is required (unless a TXV is required instead).
All Goodman coils feature an all-aluminum tube and fin coil design. Goodman uses a single metal, aluminum, and a grooved tube help to deliver the utmost in heat transfer efficiency. Aluminum construction helps to hinder potential corrosion. Like other Goodman products, the cabinet has a galvanized leather grain-embossed finish. Foil-faced insulation covers the casing inside to reduce cabinet condensate. A split seam is located on the front of the cabinet for easy access. Drain pans feature a low water-retention design and are made of DecaBDE-free thermoplastic. The thermoplastic design resists rust and is UV-resistant.
The CAPF series of evaporator coils can be connected for use in an upflow or downflow application. In an upflow installation you can take advantage of the natural flow the heat. In this type of installation, cold air enters at the bottom and hot air is exhausted out the top. The opposite is true in a downflow installation. Usually installed in attics, this installation takes cooler air into the top of the unit and released out the bottom or downward into the space. The CAPF3743D6 evaporator coils require either R410A or the newer R22 refrigerants.

Cased evaporator coils are typically used for new comfort system installations including a new furnace. They must be paired with the condenser unit in a split system - with or without a heat pump, as well as match the furnace for a proper/exact fit. Uncased coils are typically used in replacement installations in which you are inserting the coil into pre-existing ductwork.
The 21" deep cabinet is engineered to make installing the evaporator coil in an attic easy.. Professional installation by an HVAC technician is required. An HVAC tech will have the knowledge and tools required to make sure your new system is up and running properly.
All Goodman products including evaporator coils are built in the USA. They have a 10 year parts limited warranty and are AHRI Certified and ETL Listed.
