The INTERNATIONAL COMFORT PRODUCTS EVDWX42M21A is a cased, vertical V-coil evaporator coil designed for use with R-410A refrigerant systems. This coil serves as the indoor heat-exchange component in a split-system cooling or heat pump application, absorbing heat from return air and delivering conditioned air to the supply plenum. At a nominal 3.5-ton capacity, it is sized for residential and light-commercial installations where reliable latent and sensible cooling performance is required. The cased enclosure simplifies installation and maintains coil alignment during handling. Licensed HVAC technicians perform the installation as part of a matched split system or as a service replacement coil.
The EVDWX42M21A is intended for vertical upflow or downflow air handler configurations where a cased V-coil design is specified. Its compact cabinet footprint, measuring 15.063 inches long by 21 inches wide by 19.0625 inches tall, fits standard residential air handler platforms. This coil is a service replacement unit, meaning it is stocked and deployed when an existing coil fails and must be swapped without replacing the full air handler. It ships at 32 pounds, making single-technician handling practical on most residential jobs.
Designed as an OEM-style service replacement cased vertical V-coil for R-410A split-system cooling and heat pump air handlers requiring a 3.5-ton nominal evaporator coil.
Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification for handling R-410A refrigerant. Shut off all electrical power to the air handler and disconnect the refrigerant circuit before removing the existing coil. Follow local mechanical codes and manufacturer piping guidelines when making refrigerant connections; pressure-test and evacuate the system to the required micron level before recharging. Do not over-bend or kink refrigerant lineset connections during fitting.
