This is a wall-sleeve air conditioner and heater for hotel rooms, apartments, or additions where central ductwork isn't available. It's built for property managers and homeowners who need self-contained, per-room climate control with electric backup heat.
The HEC123J50AXXX is an Amana high-efficiency PTAC with electric heat, suited to hospitality guest rooms, multifamily units, and additions where ducted HVAC isn't practical. It carries an EER of 11.9/11.9 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 (WS900E / WS900QW series or compatible).
- Voltage: 230/208V. Compatible with 230/208V circuits only, within the 197V-253V operating range.
- Electric heat: 5.0/4.1 kW single-stage strip; total heat amps 22.1/20.0A; MCA 27.6A; MOP (max breaker) 30A.
- Power cord/plug: NEMA 6-30P, factory-installed LCDI cord per UL 484 (applies to units under 250V).
- Wall Sleeve is NOT included - order separately (e.g., WS900E, WS900QW, or a deeper/heavier-gauge variant as required).
- Exterior Architectural Grille is NOT included - order separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits.
- Not compatible with 265V hardwire or sub-base installations. The 265V commercial version of this chassis is the HEC124J, which requires an Amana PTSB4**E sub-base or PTPWHWK4 hard-wire kit with PSHW04A disconnect - none of that applies here.
- Not a drop-in replacement for non-standard or custom sleeve openings - verify rough-opening dimensions before ordering.
The technical friction on any PTAC retrofit is condensate management - the sleeve has to shed water to the outside, not into the wall cavity. Field crews commonly set the sleeve dead level out of habit, which stalls drainage and lets moisture wick into drywall over time, leading to mold and structural rot behind the unit. Prevent this by pitching the sleeve roughly 1/4 bubble toward the exterior wall, verified with a torpedo level set on the sleeve's base rail before it's fastened. This pitch spec follows the manufacturer's framing diagram for the 42-1/4 in x 16-1/4 in minimum rough opening, and confirming it before final fastening is standard property-management practice for avoiding callback claims on water damage.
Key Benefits
- EER rating of 11.9/11.9 at 230V/208V for verified cooling efficiency.
- Dehumidification rate of 1.7 pints/hr to help manage humidity in guest rooms and living spaces.
- Fresh-air ventilation adjustable from 65-95 CFM for make-up air control.
- Dual airflow ratings (wet/dry, high/low) give installers flexibility for room size and duct static.
- Meets or exceeds ASHRAE 90.1 efficiency standards.
- R-32 refrigerant, a lower-GWP option compared to older R-410A systems.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis fits the industry-standard 42 in x 16-1/16 in sleeve opening, such as the WS900E or WS900QW series.
What breaker size and plug type does this unit require?
This configuration requires a 30-amp circuit (MOP 30A, MCA 27.6A) and uses a NEMA 6-30P power cord plug, per the electric heat performance rating for the 5.0/4.1 kW heater at 230/208V.
Can this be hardwired for 265V commercial applications?
No. This unit is rated 230/208V only. It is not compatible with 265V circuits and cannot use the Amana PTSB4**E sub-base or PTPWHWK4 hard-wire kit, which apply to the 265V commercial sibling chassis (HEC124J).
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
[NEEDS VERIFICATION] - installation labor requirements are not specified in the provided data. Refer to the manufacturer warranty document in the Resources tab for installation terms that affect warranty validity.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis is designed for the industry-standard 42 in wide x 16-1/16 in high sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings without verifying dimensions first.
Warranty & Registration
This unit carries a 1-Year Repair/Replace warranty and a 5-Year Parts Limited Warranty on the sealed system, per manufacturer badge documentation. Exact terms, including any distinction between residential and commercial hospitality usage, are detailed in the warranty PDF under the "Resources (System Manuals and Warranty)" Tab above - review that document before installation, and ask us before you order if anything is unclear.
