Friedrich FRP15AY42AJ2NA Heat Pump 3.5 Ton 15 SEER2

Product Description

The FRIEDRICH FRP15AY42AJ2NA is a two-stage residential heat pump designed for split-system heating and cooling applications. Rated at 42,000 BTU/h cooling capacity across 3.5 nominal tons, it carries a 15 SEER2 efficiency rating and operates on R454B refrigerant, a lower-GWP alternative to R-410A now required under current EPA refrigerant transition guidelines. The two-stage compressor modulates between low and high capacity, allowing the system to match load conditions more closely than a single-stage unit. Installation is performed by a licensed HVAC technician with EPA 608 certification for handling regulated refrigerants.

This unit is suited for residential and light-commercial split-system installations where 3.5-ton capacity is specified. The R454B refrigerant charge and two-stage operation make it applicable to new construction and replacement projects requiring compliance with current efficiency and refrigerant standards. Pairing this outdoor unit requires a matched indoor coil and air handler rated for R454B and compatible with two-stage control wiring.

Key Features

• 42,000 BTU/h cooling capacity at 3.5 nominal tons
• 15 SEER2 efficiency rating meets current federal minimum standards
• Two-stage compressor operation for improved load matching and comfort
• R454B refrigerant — lower global warming potential, compliant with current EPA transition requirements

Compatibility

Designed as an OEM split-system outdoor heat pump unit requiring a matched indoor coil and air handler rated for R454B refrigerant and two-stage operation.

Installation Notes

Installation must be performed by a licensed HVAC technician holding a valid EPA 608 certification for handling mildly flammable A2L refrigerants such as R454B. Follow all local mechanical codes and the manufacturer installation manual for clearance, electrical disconnect, and refrigerant line sizing requirements. De-energize the unit and shut off the disconnect before any service work. R454B requires tools and recovery equipment rated and labeled for A2L refrigerant service — do not use equipment designated for R-410A only.
