General Electric nam42v2ta4 Air Handler 3.5 Ton

Product Description

The General Electric nam42v2ta4 is a 3.5-ton, two-piece variable speed air handling unit designed for residential and light commercial forced-air HVAC systems. It delivers conditioned air through the supply duct system by matching blower speed to system demand, which improves comfort and efficiency across a wide range of load conditions. The variable speed motor reduces energy consumption during partial-load operation compared to single-speed alternatives. Installation is handled by licensed HVAC technicians working with split or packaged refrigerant systems.

This unit is suited for residential new construction and retrofit applications where a 3.5-ton cooling or heating capacity is specified. The two-piece configuration allows for installation in tight mechanical spaces such as closets, utility rooms, and attic platforms where a single large cabinet would be difficult to maneuver. It is compatible with standard refrigerant line sets and low-voltage thermostat wiring typical of central ducted HVAC systems.

Key Features

• 3.5-ton rated capacity for residential and light commercial applications
• Variable speed blower motor adjusts airflow to match system demand
• Two-piece cabinet design simplifies installation in confined spaces
• Compatible with standard low-voltage thermostat control wiring
• Designed for use in ducted split-system HVAC configurations

Compatibility

Designed as an OEM-style air handling unit for use in 3.5-ton ducted split-system HVAC applications requiring a variable speed, two-piece configuration.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes and manufacturer guidelines. Disconnect and lock out all electrical power to the system before beginning any service or installation work. Ensure the refrigerant circuit is properly evacuated and charged by an EPA Section 608 certified technician. Verify that the existing duct system and line set sizing are appropriate for a 3.5-ton unit before completing the installation.
