An air conditioner or heat pump is only as good as its evaporator coil. Luckily, Goodman designs their evaporator coils with the same mind for accessibility, longevity, and value as their other heating and cooling equipment. The CAUF is an uncased A coil for use in upflow or downflow applications. The all-aluminum construction and advanced design of this coil improve its durability and heat transfer efficiency. Whether you're replacing a failing coil or installing a new system, you can choose the CAUF with confidence. Goodman pressure tests each coil twice before it leaves the factory and backs them with an excellent warranty.
