This is a wall-sleeve air conditioner and electric heater built for hotel rooms, apartments, or additions where central ductwork isn't available. It's a 265V commercial unit for property managers and contractors who need self-contained, per-room climate control on a dedicated circuit.
The HEC074J35AXXX is a 265V packaged terminal air conditioner with electric heat, sized for hospitality rooms, additions, and multi-family units where a wall sleeve replaces central ductwork. It's built on Amana's HEC (High-Efficiency Cooler) chassis and meets or exceeds ASHRAE 90.1 efficiency standards. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Critical Fit & Power Requirements
- Wall sleeve opening: industry-standard 42 in wide x 16-1/16 in high (Amana WS900E / WS900QW or compatible sleeve series).
- Voltage: 265V. Operating range per manufacturer note: 239V minimum / 292V maximum.
- Electric heat: 3.7 kW, single stage, 12,600 BTU heating output at 265V.
- Electrical requirements with heater: 17.9A MCA, 20A MOP, 14.2A total amps, 3,770 total watts.
- Power cord: factory-installed NEMA 7-20P plug.
- Required accessory (not included): Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A. 265V units cannot operate on a standard cord-and-plug wall receptacle alone without one of these.
- 265V models use factory-installed cartridge-style time-delay fuses, not a standard LCDI cord — the LCDI power cord (UL 484) applies only to units under 250V.
- Wall Sleeve is NOT included. Exterior Architectural Grille is NOT included. Both must be ordered separately.
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — for a 230/208V version of this chassis, see sibling model HEC073J.
- Not a drop-in fit for non-standard or custom wall sleeve openings.
On 265V PTAC replacements, the technical friction point is almost never the chassis — it's the sub-base wiring and receptacle mismatch. Field crews sometimes reuse an old 230V sub-base assuming "close enough," which leaves the unit under-fused and the disconnect rated wrong for 14.2A total draw at 3.7 kW heat. Confirm the sub-base is the Amana PTSB4**E series (or install the PTPWHWK4 hard-wire kit with PSHW04A disconnect) rated for 265V before setting the chassis, and verify polarity and voltage at the receptacle with a multimeter against the NEMA 7-20P pin configuration. This prevents nuisance trips, overheated conductors, and callbacks that show up months later as a "no heat" complaint. Torque the sub-base lugs to the disconnect manufacturer's spec and log it — most property management preventive-maintenance programs require documented torque values on commercial electrical connections at PTAC turnover, and it satisfies NEC Article 440 grounding and disconnect requirements for room air conditioners.
Key Benefits
- 14 EER rating on the cooling side for verified efficiency at this capacity.
- 1.7 pints/hr dehumidification for moisture control in occupied rooms.
- Adjustable fresh-air ventilation, 65-95 CFM, for make-up air in tightly sealed rooms.
- R-32 refrigerant chassis (lower GWP than legacy R-410A systems).
- Single-stage 3.7 kW electric heat strip delivers 12,600 BTU of supplemental heat at 265V.
- Meets or exceeds ASHRAE 90.1 commercial efficiency standards.

Compatibility & Fitment
- Fits the industry-standard 42 in wide x 16-1/16 in high wall sleeve opening.
- Compatible with 265V circuits only, using a NEMA 7-20P plug, when paired with the required Amana sub-base or hard-wire kit.
- Requires an Amana PTSB4**E series sub-base or PTPWHWK4 hard-wire kit with PSHW04A disconnect — sold separately, not included with this unit.
- Wall Sleeve NOT included — order separately (e.g., WS900E, WS900QW, or applicable variant).
- Exterior Architectural Grille NOT included — order separately.
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — use sibling model HEC073J for a 230/208V installation instead.
- Not a drop-in replacement for non-standard or custom-sized sleeve openings.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit fits the industry-standard 42 in wide x 16-1/16 in high wall sleeve opening (e.g., Amana WS900E / WS900QW series), but the sleeve and exterior architectural grille must be purchased separately.
What breaker size and plug type does this unit require?
This 265V configuration with 3.7 kW electric heat requires a Minimum Circuit Ampacity of 17.9A and a Maximum Overcurrent Protection of 20A. It ships with a factory-installed 7-20P power cord.
Can this be hardwired for 265V commercial applications?
Yes. All 265V Amana PTAC models must be paired with an Amana brand sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit with PSHW04A disconnect switch. Neither is included with this unit and must be ordered separately.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
265V circuits and the associated sub-base or hard-wire kit are commercial-grade electrical work. Installation should follow NEC receptacle and disconnect requirements. Exact warranty conditions are detailed in the manufacturer warranty document in the Resources tab.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis is designed for the industry-standard 42 in x 16-1/16 in wall sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings.
