Friedrich FRP14AY42AJ2NA Heat Pump 3.5 Ton 14 SEER2

Product Description

The FRIEDRICH FRP14AY42AJ2NA is a two-stage residential heat pump rated at 3.5 nominal tons and 42,000 BTU/h cooling capacity. It operates on R454B refrigerant and carries a 14 SEER2 efficiency rating, meeting current federal minimum efficiency standards for split-system heat pumps. The two-stage compressor design allows the unit to run at a lower capacity stage during mild conditions, reducing runtime cycling and improving dehumidification performance. Licensed HVAC technicians install and commission this equipment as the outdoor condensing unit in a split-system heat pump configuration.

This unit is suited for residential and light-commercial applications requiring 3.5 tons of cooling and heating capacity. It is designed for split-system installation paired with a compatible air handler or furnace coil. The two-stage operation makes it a practical choice for climates with variable cooling and heating loads, where a single-stage unit would otherwise short-cycle. Installation must comply with applicable local mechanical codes and EPA Section 608 refrigerant handling requirements for R454B, an A2L mildly flammable refrigerant.

Key Features

• 42,000 BTU/h cooling capacity at 3.5 nominal tons
• 14 SEER2 rated efficiency meeting current federal minimums
• Two-stage compressor operation for improved part-load performance and dehumidification
• R454B refrigerant charge — an A2L low-GWP refrigerant requiring certified handling
• Outdoor condensing unit configuration for split-system heat pump installations

Compatibility

Designed as an OEM split-system heat pump outdoor unit intended for pairing with a compatible matched indoor air handler or furnace coil. Consult FRIEDRICH published matchup data to confirm rated system efficiency with a specific indoor unit before installation.

Installation Notes

Installation must be performed by an EPA 608-certified HVAC technician due to the use of R454B, which is classified as an A2L mildly flammable refrigerant requiring specific handling procedures and leak detection practices. Disconnect and lock out all electrical power to the system before making any electrical or refrigerant connections. Follow local mechanical codes, NEC requirements for disconnect sizing and wire gauge, and the manufacturer installation instructions for clearance, pad mounting, and line set sizing. Do not use recovery equipment or refrigerant handling tools not rated for A2L refrigerants with this unit.
