Maytag 921953 Evaporator Coil 18.125x25 in 3-row Txv

Product Description

The MAYTAG 921953 is an uncased tube and fin evaporator coil designed as a direct replacement component for Maytag indoor air handler systems. Measuring 18.125 inches by 25 inches with a 5.58 square foot face area, this coil provides efficient heat exchange in split-system cooling and heat pump applications. It features a 3-row depth configuration with 14 fins per inch and a 0.08-inch orifice, and is engineered for use with a TXV metering device. Licensed HVAC technicians typically handle replacement of evaporator coils as part of system servicing or refrigerant circuit repair.

This evaporator coil is intended for use in residential indoor air handler installations where the original coil requires replacement. It is specifically noted for compatibility with the B6BMX and B6VMAX series indoor air handlers. The uncased design suits installations where the existing air handler cabinet houses the coil assembly. The TXV-compatible metering configuration allows precise refrigerant flow control, supporting system efficiency across a range of operating conditions common in residential split-system HVAC setups.

Installation Notes

Evaporator coil replacement must be performed by a licensed HVAC technician, as the work involves handling refrigerant under EPA Section 608 regulations. Shut down and de-energize the air handler and disconnect the refrigerant circuit before removing the existing coil. Verify TXV sizing and refrigerant line connections before completing system recharge. Follow applicable local mechanical codes and manufacturer service documentation throughout the installation process.
