Trane A5AC5048A1000 Split System Air Conditioner 48000 Btu 4 Ton 15.2 SEER2 Single Stage R-454B

Product Description

The Trane A5AC5048A1000 is a single-stage outdoor condensing unit from the RunTru by Trane product line, delivering 48,000 BTU/h (4 tons) of cooling capacity at 15.2 SEER2 efficiency. The unit operates on R-454B refrigerant and is factory charged with the full system refrigerant load. It runs on a 208-230/1/60 electrical supply with 24-volt system control and is built with an all-aluminum coil construction. Licensed HVAC technicians install this unit as part of a ducted central split cooling system, pairing it with a compatible indoor air handler to complete the refrigerant circuit and airflow path.

This condenser is designed for residential ducted central cooling applications. It is a single-stage unit, meaning the compressor operates at one capacity level, making it well suited for straightforward load-matching in homes that do not require variable-capacity staging. The unit has a rated sound power level of 71 dB(A), which is typical for outdoor condensing units in this capacity class. Nominal dimensions are 34.25 inches wide and 22.875 inches deep, with an operating weight of 257 pounds. Based on available documentation, compatible indoor air handler pairings include the A5AHC006A1D30A, a convertible R-454B air handler with a 4-way poise all-aluminum plate fin coil.

Key Features

• 48,000 BTU/h (4-ton) single-stage cooling output at 15.2 SEER2
• R-454B refrigerant — factory charged to full system charge at the plant
• All-aluminum coil construction for corrosion resistance in outdoor exposure
• 24-volt system control interface, compatible with standard thermostat wiring
• 208-230/1/60 power supply — single-phase, suitable for standard residential service
• Rated sound power level of 71 dB(A) per AHRI Standard 270-2008
• Maximum overcurrent protection of 35 amps

Compatibility

Documented compatible indoor pairing includes the A5AHC006A1D30A convertible air handler. This condensing unit is part of the A5AC5 model family and is intended for use in ducted central split cooling systems designed for R-454B refrigerant. Do not pair with indoor coils or air handlers rated for R-410A without confirming refrigerant compatibility.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician due to the R-454B refrigerant, which is classified as an A2L mildly flammable refrigerant requiring adherence to current ASHRAE 15 and local mechanical code requirements. Disconnect and lock out all electrical power to both the indoor and outdoor units before performing any service work. The unit is factory charged and should not require additional refrigerant charge on a properly sized new installation, but system pressures should be verified after startup. Follow the manufacturer installation, operation, and maintenance documentation for mounting clearances, line set sizing, and electrical rough-in requirements.
