Rheem ra14ay48aj1nalhp 4 Ton Ac Condenser 14.3 SEER2

Product Description

The RHEEM ra14ay48aj1nalhp is a 4-ton single-stage air conditioner condenser rated at 14.3 SEER2, designed for residential central cooling systems. It operates on R-454B refrigerant, a lower-GWP alternative that meets current EPA regulations and is positioned for long-term compliance as refrigerant transition standards evolve. Single-stage operation delivers consistent, reliable cooling output at a fixed capacity, making it a straightforward replacement or new-install choice for standard load calculations. Licensed HVAC technicians handle installation and commissioning of this outdoor condensing unit.

This condenser is suited for residential split-system cooling applications where a 4-ton capacity matches the calculated heat load of the structure. It pairs with a compatible indoor air handler or coil to form a complete split system. The 14.3 SEER2 efficiency rating meets current minimum efficiency standards under the DOE 2023 regional requirements. Typical installations are ground-mounted on a level pad adjacent to the structure, with refrigerant line sets and electrical disconnect run by a licensed mechanical and electrical contractor.

Key Features

• 4-ton cooling capacity for residential split-system applications
• 14.3 SEER2 efficiency rating meets current DOE regional minimum standards
• R-454B refrigerant — lower global warming potential, EPA-compliant formulation
• Single-stage compressor operation for straightforward capacity control
• Outdoor condensing unit designed for ground-level pad installation

Compatibility

Designed as an OEM-style residential split-system condensing unit intended to pair with a compatible indoor evaporator coil or air handler rated for R-454B refrigerant and matched to 4-ton capacity.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification for handling refrigerants. Disconnect and lock out all electrical power at the main panel and the local disconnect before beginning any service or connection work. The unit should be set on a level concrete or composite pad following local mechanical codes and the manufacturer installation instructions. Do not use R-410A or any refrigerant other than R-454B in this system, as the components are designed and rated specifically for R-454B.
