Description
The Goodman CAUTA1818A3 1.5 Ton uncased evaporator coil is an R-32 indoor coil built for matched Goodman split systems. Its uncased design lets installers fit it directly into an existing plenum or a field-built cabinet, making it a practical choice for replacement work where space is tight.
Sized for 1.5 tons (18,000 BTU) of cooling, the CAUTA1818A3 measures 14.0" wide by 18.0" tall and supports upflow / downflow installations. A factory-installed TXV meters refrigerant precisely for consistent performance with R-32 condensers and heat pumps.
