Friedrich FRA15AY42AJ1NALHP Condensing Unit 3.5T 15 SEER2

Product Description

The FRIEDRICH FRA15AY42AJ1NALHP is a 3.5-ton residential split-system condensing unit rated at 15 SEER2 and designed to operate on R454B refrigerant. This outdoor unit houses the compressor, condenser coil, and condenser fan motor, rejecting heat absorbed from the indoor coil. At 42,000 BTU/h of cooling capacity, it is sized for mid-to-large residential applications. Single-stage operation means the compressor runs at full capacity when called, providing straightforward staging logic for compatible air handlers and coils. Licensed HVAC technicians perform installation and commissioning, including refrigerant handling under EPA Section 608 certification requirements.

This condensing unit is intended for residential split-system cooling installations where an outdoor unit pairs with a compatible indoor evaporator coil and air handler. Single-stage capacity suits homes in the range typically served by 3 to 4-ton equipment. The R454B refrigerant charge is a lower-GWP A2L refrigerant, meaning installers must follow current local codes and manufacturer guidelines addressing A2L flammability classification during service, installation, and commissioning.

Key Features

• 42,000 BTU/h cooling capacity serves mid-to-large residential loads
• 15 SEER2 efficiency rating meets current federal minimum efficiency standards
• R454B refrigerant charge uses a lower-GWP, A2L-classified refrigerant
• Single-stage compressor operation simplifies controls integration with compatible air handlers
• 3.5-ton nominal capacity for flexible residential split-system applications

Compatibility

Designed for use in residential split-system cooling or heat pump applications requiring a 3.5-ton, single-stage outdoor condensing unit compatible with R454B refrigerant and rated at 15 SEER2. Pair with a manufacturer-approved indoor evaporator coil and air handler to achieve rated system efficiency.

Installation Notes

Installation must be performed by an EPA Section 608-certified HVAC technician with experience handling A2L refrigerants, as R454B carries a mild flammability classification requiring adherence to updated code requirements and safe-handling procedures. Disconnect and lock out all electrical power before beginning any work on the unit. Follow local mechanical and electrical codes, including applicable sections of the NEC, for disconnect sizing, wiring, and clearances. Do not attempt to field-modify refrigerant circuit components or substitute a different refrigerant type.
