Trane A5PH3042A1000 Single Packaged Heat Pump 3.5 Ton 13.4 SEER2 Convertible R-454B

Product Description

The Trane A5PH3042A1000 is a single-package electric heat pump designed for residential applications where both heating and cooling functions must be housed in one self-contained cabinet. Rated at 3.5 tons with a 13.4 SEER2 efficiency rating, this unit operates on 208-230V/1-phase/60Hz power and uses R-454B refrigerant, the low-GWP refrigerant required under current EPA regulations. The unit delivers 43,000 BTU of cooling capacity and 39,000/24,400 BTU of heating capacity, with a rated airflow of 1,440 CFM. HSPF2 is rated at 6.7 BTU per watt-hour, and the unit maintains heating operation down to 17 degrees F outdoor ambient. Licensed HVAC technicians handle installation, startup, and commissioning.

The A5PH3042A1000 is configured for convertible airflow, meaning it supports both downflow and horizontal discharge orientations. This makes it suitable for rooftop, slab, or curb-mount installations on residential or light-commercial structures where a single outdoor cabinet serves as the complete system. The unit is part of the RunTru by Trane product line and is listed as model A5PH3042A1000A in Trane product and submittal documentation. Minimum branch circuit ampacity is 31 amps. Power input at rated conditions is 3.12 kW.

Compatibility

This unit is part of the Trane single packaged heat pump entry-level series covering 2 to 5 ton capacities, documented under Trane literature reference PKGR-PSD015B-EN. It is designed as a self-contained replacement or new-construction packaged heat pump for residential and light-commercial curb, slab, or rooftop installations.

Installation Notes

Installation must be performed by a licensed HVAC technician holding EPA 608 certification, as this unit contains R-454B refrigerant. Before any service or electrical connection work, disconnect and lock out all power at the breaker. Verify that branch circuit wiring meets the 31-amp minimum ampacity requirement and is sized in accordance with the NEC. Confirm the installation orientation, downflow or horizontal, before mounting, as duct connections and drain routing differ between configurations.
