Ruud RA13NY18AJ1NALHP Condensing Unit 1.5 Ton R454B

Product Description

The RUUD RA13NY18AJ1NALHP is a 1.5-ton residential air conditioning condensing unit designed for split-system cooling applications. Rated at 18,000 BTU/h and achieving 13 SEER2 efficiency, this unit operates on R454B refrigerant, a lower-GWP alternative that meets current EPA requirements for new residential equipment. Part of the RUUD M1 series, it is sized for smaller residential loads and is typically installed by a licensed HVAC technician as the outdoor section of a split cooling system paired with an indoor air handler or coil cabinet.

This condensing unit is suited for residential split-system cooling installations where a 1.5-ton capacity meets the Manual J load calculation. The M1 series is positioned as an entry-level efficiency offering that complies with 2023 DOE SEER2 regional standards. It is commonly specified in smaller homes, additions, or single-zone applications. The R454B refrigerant charge requires technicians to be certified under Section 608 of the Clean Air Act and to use tooling compatible with mildly flammable A2L refrigerants.

Key Features

• 18,000 BTU/h nominal cooling capacity at 1.5 tons
• 13 SEER2 efficiency rating meets current DOE regional minimum standards
• R454B refrigerant — lower global warming potential, A2L classified
• Part of the RUUD M1 series for residential split-system cooling
• Outdoor condensing unit designed to pair with a compatible indoor coil or air handler

Compatibility

Designed as an OEM-style residential condensing unit for split-system cooling applications. No specific compatible indoor unit model numbers were provided in the product data. Consult RUUD engineering documentation to confirm matched indoor coil or air handler pairings for rated system efficiency.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician; R454B is an A2L mildly flammable refrigerant that requires approved recovery equipment and leak-detection practices. Disconnect and lock out all electrical power to the system before making any electrical or refrigerant connections. The unit should be mounted on a level pad with adequate clearance per the manufacturer installation instructions and local mechanical codes. Follow all applicable local codes and ASHRAE 15 safety requirements when working with A2L refrigerants.
