Trane A5PG3042A1090 Single Packaged Gas Electric Unit 40000 Btu Cooling 90000 Btu Heating 3.5 Ton R-454B

Product Description

The Trane A5PG3042A1090 is a single packaged gas/electric heating and cooling unit designed for residential and light-commercial rooftop or ground-level installations. It delivers 40,000 BTU/h of cooling capacity at 3.5 tons and 90,000 BTU/h of first-stage natural gas heating input, all in a self-contained cabinet that eliminates the need for separate indoor and outdoor equipment. The unit operates on 208-230 volts, single phase, 60 Hz and uses R-454B refrigerant, a lower-global-warming-potential alternative to R-410A. Rated at 13.40 SEER2 and an EER2 of 10.6, it meets current efficiency standards. Licensed HVAC technicians handle installation and commissioning.

The A5PG3042A1090 is built for multiposition application, making it suitable for rooftop curb-mount or ground-pad installations in residential new construction and replacement projects. It is part of the Trane A5PG3042A product family, which spans 2 to 5 ton configurations in the same platform. The unit is listed alongside models A5PG3024A1060A, A5PG3030A1070A, A5PG3036A1070A, A5PG3048A1090A, and A5PG3060A1115A as members of the same convertible, entry-level packaged gas/electric series. Typical applications include replacing aging package units on small commercial buildings, mobile homes with rooftop configurations, or residential structures where a split system is not practical.

Compatibility

The A5PG3042A1090 is part of the Trane A5PG3042A product family and is documented alongside models A5PG3024A1060A, A5PG3030A1070A, A5PG3036A1070A, A5PG3048A1090A, and A5PG3060A1115A in the same product data series.

Installation Notes

Installation must be performed by a licensed HVAC technician in accordance with local mechanical codes, IFGC requirements for gas piping, and NEC requirements for electrical connections. Disconnect and lock out all electrical power and close the gas shutoff valve before servicing the unit. Rooftop installations require a code-compliant curb that matches the unit footprint; confirm curb dimensions before ordering. R-454B requires recovery equipment rated for A2L refrigerants — do not use legacy R-22 or R-410A recovery cylinders.
