Ruud RA15AY18AJ1NALHP Condensing Unit 1.5 Ton R454B 15 SEER2

Product Description

The RUUD RA15AY18AJ1NALHP is a 1.5-ton residential split-system condensing unit rated at 18,000 BTU/h cooling capacity. It operates on R454B refrigerant, a lower-GWP A2L alternative to R-410A, and carries a 15 SEER2 efficiency rating under the DOE M1 test methodology. Part of the RUUD M1 series, this outdoor unit houses the compressor, condenser coil, and fan assembly. It is designed to pair with a matched indoor evaporator coil and air handler to complete a split cooling system. Licensed HVAC technicians install and service this equipment.

This condensing unit is suited for residential light-commercial split-system cooling applications. The M1 series designation aligns with current DOE regional efficiency standards. At 1.5 nominal tons, it is commonly applied in smaller residential spaces or single-zone applications where moderate cooling capacity is appropriate. A matched indoor coil and compatible air handler or furnace with blower are required to complete the system installation.

Key Features

• 18,000 BTU/h nominal cooling capacity at 1.5 tons
• R454B refrigerant — lower global warming potential A2L refrigerant
• 15 SEER2 efficiency rating under DOE M1 test standards
• M1 series platform designed to meet current regional efficiency requirements
• Outdoor condensing unit configuration — houses compressor, condenser coil, and fan

Compatibility

Designed as an OEM split-system outdoor condensing unit intended to pair with a compatible matched indoor evaporator coil and air handler within the RUUD M1 series product line. No specific indoor unit model numbers were provided in the available data.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, as R454B carries a mild flammability classification requiring adherence to current local mechanical codes and manufacturer guidelines. 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 for airflow and service access per the installation manual. R454B requires tools and recovery equipment rated and listed for A2L refrigerant service.
