Ruud RA15AY48AJ1NALHP Condensing Unit 4 Ton R454B 15 SEER2

Product Description

The RUUD RA15AY48AJ1NALHP is a 4-ton residential air-cooled condensing unit from the M1 series, rated at 48,000 BTU/h cooling capacity and 15 SEER2 efficiency. It operates on R454B refrigerant, a lower-GWP replacement for R-410A that meets current environmental regulations. This unit pairs with a compatible indoor coil and air handler to complete a split-system cooling installation. Licensed HVAC technicians handle installation and refrigerant service in compliance with EPA Section 608 requirements.

This condensing unit is suited for residential cooling applications requiring a 4-ton system. The M1 series designation places it in the standard efficiency tier, making it appropriate for new installations and direct replacements where a 15 SEER2 rating satisfies local energy code minimums. Typical installation scenarios include single-family homes and light-duty applications where a matched split system is configured with a TXV-equipped indoor coil.

Key Features

• 48,000 BTU/h nominal cooling output for 4-ton system sizing
• 15 SEER2 rated efficiency meets current minimum federal standards
• R454B refrigerant charge — lower global warming potential versus R-410A
• M1 series platform designed for residential split-system cooling

Compatibility

Designed as an OEM-style residential condensing unit for use in a matched split-system configuration. A compatible indoor coil and air handler rated for R454B refrigerant are required. Consult RUUD expanded rating tables to confirm matched system SEER2 certification before installation.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician. Disconnect all power to the system before any service work begins. R454B is an A2L mildly flammable refrigerant — follow applicable local codes and manufacturer guidelines for handling, leak detection, and system evacuation. Size the line set, disconnect, and overcurrent protection to match the unit nameplate ratings.
