General Electric NAS24E1TB5S 2 Ton Ecm Compact Air Handler

Product Description

The GENERAL ELECTRIC NAS24E1TB5S is a 2-ton, single-piece compact air handler designed for residential split-system cooling and heating applications. It uses an Electronically Commutated Motor (ECM) for variable-speed airflow, which improves efficiency and reduces energy consumption compared to standard PSC motor units. Rated at 24000 BTU/h, this unit is compatible with R454B refrigerant, a lower-global-warming-potential alternative to R410A now required in new equipment. Licensed HVAC technicians handle installation and commissioning of this equipment.

The NAS24E1TB5S is suited for residential applications where a compact, all-in-one air handler footprint is required. The single-piece construction simplifies installation in tight mechanical spaces such as closets, attics, or utility rooms. Its ECM motor delivers variable airflow to match system demand, making it well-suited for pairing with modern variable-capacity or two-stage outdoor condensing units. The R454B refrigerant designation means this unit meets current low-GWP refrigerant requirements for new residential HVAC equipment.

Compatibility

Designed as an OEM-style compact air handler for residential split-system HVAC applications using R454B refrigerant with a 2-ton outdoor condensing unit.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification, as this unit contains refrigerant. Disconnect all electrical power and ensure the refrigerant circuit is properly recovered before servicing any connected components. Follow local mechanical and electrical codes for equipment support, drain line routing, and low-voltage thermostat wiring. Consult the manufacturer installation manual for approved refrigerant line sizing and evacuation procedures specific to R454B systems.
