Allied Air 25m03 Air Handler 2.5 Ton 208/230V R-454B

Product Description

The ALLIED AIR 25m03 is a residential indoor air handler designed for split-system cooling and heat pump applications using R-454B refrigerant. Rated at 2.5 tons nominal capacity, this unit operates on 208/230V single-phase power at 60 Hz and delivers up to 1,341 CFM of airflow. The cabinet is constructed from galvanized steel and houses a constant torque motor, which maintains consistent airflow performance across a range of static pressure conditions. Licensed HVAC technicians install this unit as the indoor section of a matched split system, connecting it to an outdoor condensing unit or heat pump.

This air handler is suited for residential new-construction and replacement installations where R-454B refrigerant is specified. The unit is configured for indoor installation and connects to refrigerant line sets via a 3/8-inch liquid line and a 3/4-inch suction line. At 47 inches tall and 27 inches wide, it fits standard vertical air handler installations in utility closets, mechanical rooms, and attic platforms. The 1,341 CFM airflow rating supports typical 2.5-ton system designs in residential applications.

Installation Notes

Installation must be performed by a licensed HVAC technician. De-energize all electrical circuits and recover or isolate refrigerant before servicing or connecting line sets. R-454B is an A2L mildly flammable refrigerant — follow all applicable local codes, ASHRAE 15, and manufacturer handling guidelines during installation. Verify electrical supply matches the 208/230V single-phase requirement and that line set sizing matches the specified 3/8-inch liquid and 3/4-inch suction connections before startup.
