Maytag 921951 Tube Fin Evaporator Coil 12.75x19 in

Product Description

The MAYTAG 921951 is a tube and fin evaporator coil designed for use in residential indoor air handler units. This replacement coil measures 12.75 inches by 19 inches and delivers 4.18 square feet of face area across a 3-row, 14-fin-per-inch configuration. The coil features a 0.067-inch orifice and is paired with TXV metering, making it a direct fit for systems requiring thermostatic expansion valve operation. Licensed HVAC technicians install this coil during coil replacement service or system refurbishment when the original coil has failed due to corrosion, refrigerant leaks, or physical damage.

This evaporator coil is intended for use in indoor air handler applications, specifically as a replacement component in the B6BMX and B6VMAX indoor air handler product lines. The uncased design fits within the existing air handler cabinet, and the replacement configuration mirrors the OEM part dimensions and fin geometry. It is suited for residential split-system cooling installations where TXV metering is already part of the refrigerant circuit.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle refrigerants under EPA Section 608 requirements. Shut down the air handler and disconnect power before beginning coil removal or installation. The refrigerant circuit must be properly recovered before removing the existing coil, and the system should be leak-tested and evacuated before recharging after the new coil is seated. Follow manufacturer service instructions and local mechanical codes throughout the procedure.
