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, so it's built for property managers and electricians working in hospitality or multi-family buildings with 265V circuits already in place — not a drop-in swap for a standard household outlet.
The PTC124J50AXXX is a standard-cooler PTAC chassis paired with a 5.0 kW electric heat strip, built for hospitality and multi-family properties running 265V circuits — common in new construction and larger commercial retrofits. The unit uses R-32 refrigerant and is rated to meet or exceed 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 (WS900E / WS900QW series, 14 in standard depth).
- Voltage: 265V commercial circuit. Voltage range must stay within 239V–292V for proper operation.
- Electric heat: 5.0 kW, single stage, rated 17,100 BTU/h heating output at 265V.
- Total electrical load with heater: 19.2A total amps, 23.9A MCA, requires a 25A overcurrent device (MOP).
- Power cord: factory 7-30P plug, matched to a 265V NEMA 7-30R receptacle.
- 265V units require an Amana sub-base (PTSB4**E series) or the PTPWHWK4 hardwire kit with PSHW04A disconnect switch — both sold separately. This is not a cord-and-plug-only install like lower-voltage models.
- Wall Sleeve is NOT included.
- Exterior Architectural Grille is NOT included.
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — for a 230/208V version of this chassis, see the sibling model PTC123J, which uses a different power cord and heater electricals.
- Not a drop-in fit for non-standard or custom sleeve openings; verify sleeve dimensions before ordering.
Key Benefits
- EER of 11.2 on the cooling side, with 11,800 BTU/h cooling capacity for single-room zoning.
- Single-stage 5.0 kW electric heat strip delivers 17,100 BTU/h of supplemental heat at 265V.
- 1.7 pints/hr dehumidification helps manage humidity in guest rooms and additions without a separate dehumidifier.
- 65 CFM fresh-air ventilation option for makeup air in tightly sealed rooms.
- R-32 refrigerant and ASHRAE 90.1-compliant efficiency for commercial specification projects.
- Factory-installed cartridge-style time-delay fusing standard on 265V units for circuit protection.

Compatibility & Fitment
- Fits the industry-standard 42 in x 16-1/16 in wall sleeve opening (WS900E / WS900QW series and compatible variants).
- Compatible with 265V circuits only, within a 239V–292V operating range, using the 7-30P cord and a 265V sub-base or hardwire kit (sold separately).
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — use sibling model PTC123J for a 230/208V install.
- Wall Sleeve NOT included — order separately (e.g., WS900E, WS900QW, or a compatible variant matched to your framing).
- Exterior Architectural Grille NOT included — order separately (SGK, AGK, or PGK series).
- Not a drop-in fit for custom or non-standard sleeve openings; confirm rough-opening dimensions before purchase.

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 opening (WS900E / WS900QW sleeve series, 14 in standard depth).
What breaker size and plug type does this unit require?
With the 5.0 kW electric heater installed, this unit has an MCA of 23.9A and requires a 25A overcurrent device (MOP). It ships with a 7-30P power cord for a matching 265V NEMA 7-30R receptacle.
Can this be hardwired for 265V commercial applications?
Yes. All 265V Amana PTAC models must be installed with an Amana brand sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit paired with the PSHW04A disconnect switch. These are sold separately and are required for 265V installs; this is a factory time-delay-fuse-equipped unit and is not intended for plug-and-play use on standard household circuits.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
265V commercial installations involve dedicated circuits, sub-base or hardwire kit selection, and cartridge-style time-delay fusing. This work should be performed by a licensed electrician or HVAC professional familiar with NEC receptacle and disconnect requirements. Refer to the warranty documentation in the Resources tab for exact installation terms.
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 fit for non-standard or custom sleeve openings without verifying dimensions against the sleeve model you select.
