Ruud RA13NY42AJ1NALHP Condensing Unit 3.5 Ton R454B

Product Description

The RUUD RA13NY42AJ1NALHP is a residential split-system air conditioning condensing unit rated at 42000 BTU/h (3.5 nominal tons) and designed to operate on R454B refrigerant at 13 SEER2 efficiency. The unit houses the compressor, condenser coil, and condenser fan motor in a single outdoor cabinet, rejecting heat from the refrigerant circuit to the surrounding air. It is part of the M1 series and is installed by licensed HVAC technicians as the outdoor half of a split cooling system paired with a matched indoor air handler or coil. The R454B refrigerant charge is a lower-GWP A2L blend, so technicians must verify their equipment and procedures are rated and compliant for A2L refrigerants before servicing.

This condensing unit is suited for residential cooling applications where a 3.5-ton system capacity is required. It pairs with a compatible indoor evaporator coil or air handler to form a complete split-system cooling circuit. The M1 series is designed for standard residential installations and is a direct-expansion cooling-only unit. Contractors selecting this unit should confirm that the matched indoor coil and refrigerant line set are rated for use with R454B to achieve the published 13 SEER2 rating and to meet current efficiency standards.

Key Features

• 42000 BTU/h nominal cooling capacity (3.5 tons)
• 13 SEER2 efficiency rating meets current minimum efficiency standards
• Operates on R454B, a lower-GWP A2L refrigerant replacing R410A
• M1 series platform designed for residential split-system cooling
• Outdoor condensing unit configuration houses compressor and condenser fan in one cabinet

Compatibility

Designed as an OEM-style residential split-system condensing unit intended for pairing with a compatible R454B-rated indoor evaporator coil or air handler. No specific compatible indoor unit model numbers were provided in the product data.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification; A2L refrigerant handling requires equipment and procedures specifically rated for flammable refrigerant classifications. Disconnect and lock out all electrical power to the system before making any refrigerant, electrical, or mechanical connections. Follow all local mechanical and electrical codes, including NEC requirements for disconnect sizing and clearance. The unit should be mounted on a level pad with adequate clearance on all sides per manufacturer installation instructions.
