Evaporator coils are used in combination with split air conditioners - with or without heat pumps. The Goodman CAPT3743C4 indoor evaporator coil is a cased coil with factory-installed thermal expansion valve (TXV) for cooling and heat pump applications. A TXV controls the rate the refrigerant flows into the evaporator, depending on conditions, for optimum performance. The CAPT3743C4 can be used with 36,000 (3 ton) to 42,000 (3.5 ton) BTU systems.
Included on all Goodman coils is the all-aluminum tube and fin coil construction. The use of single metal construction and a grooved tube help to deliver the most in heat transfer efficiency. Aluminum construction helps to hinder potential corrosion. The cabinet is finished in the same galvanized, leather grain-embossed finish as other Goodman system components. Foil-faced insulation covers the casing inside to reduce cabinet moisture. 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 CAPT series of evaporator coils can be set up for use in an upflow or downflow application. A downflow installation is typically used for attic installations, whereas an upflow installation is mainly in a cellar of the building. The CAPT evaporator coils require R410A refrigerant.

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 evaporator coil cabinet is 21" deep for easier attic access. This unit can be purchased by anyone, however, HVAC systems must be installed by a certified HVAC technician. An HVAC installer will have the experience required to make sure your new system is up and running properly.
Like all Goodman equipment, evaporator coils are designed, engineered, and built in the USA and built to last. They include a 10 year parts limited warranty and are AHRI Certified and ETL Listed.
