This is a wall-sleeve heat pump 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 cooling and heating in one chassis.
This PTH124J25AXXX pairs the Amana PTH124J heat pump chassis with a factory-installed 2.5 kW electric heat strip for 265V circuits, giving you compressor-driven heating with electric-resistance backup for cold-snap performance. It's suited to hospitality corridors, additions, and multi-family units where a heat pump reduces electric heat runtime compared to strip-heat-only PTAC models. Amana PTAC/PTHP chassis are built 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 required: 42 in wide x 16-1/16 in high (standard depth 14 in for WS900E / WS900QW sleeves).
- Voltage: 265V (operating range 239–292V). This is a commercial voltage class — not for 115V or 230/208V circuits.
- Electric heat: 2.5 kW, single-stage, 9.7 total amps, 12.2 MCA, 15A MOP.
- Plug/cord: NEMA 7-20P power cord included with the unit.
- Wall Sleeve NOT included — sold separately.
- Exterior Architectural Grille NOT included — sold separately (SGK, AGK, or PGK grille required).
- Required for 265V operation: Amana sub-base (PTSB4**E series) or hardwire kit PTPWHWK4 with disconnect PSHW04A — neither is included.
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — for that voltage, use sibling chassis PTH123J instead.
- Not a drop-in replacement for non-standard or custom sleeve openings.
On 265V hospitality retrofits, techs often reuse an existing 230/208V sub-base because it "looks the same" — it isn't, and the receptacle configuration won't accept the 7-20P plug on this unit correctly, or worse, gets force-fit and arcs under load. Always cross-check the sub-base model plate against a NEMA receptacle chart before energizing the circuit — the PTSB4**E series is the correct family for 265V Amana chassis. This isn't optional: mismatched sub-bases on 265V circuits are a documented cause of overheated terminals and nuisance breaker trips in multi-room hotel wings. Confirm cartridge-style time-delay fuse presence in the sub-base per NEC Article 440 before handing the room back to property management.
Key Benefits
- Heat pump operation (11,500 BTU/h heating) reduces reliance on electric strip heat in moderate outdoor conditions, cutting electric heat runtime versus strip-only PTAC units.
- 1.7 pints/hr dehumidification rate helps manage humidity in guest rooms and multi-family units without a separate dehumidifier.
- Fresh air ventilation adjustable from 65–95 CFM for make-up air in tightly sealed rooms.
- 11.3 EER cooling / 3.3 COP heating efficiency, rated to meet or exceed ASHRAE 90.1.
- R-32 refrigerant chassis.
- Compact 108 lb net weight (125 lb shipping) simplifies sleeve-mounted install and removal for service.

Compatibility & Fitment
- Fits industry-standard 42 in wide x 16-1/16 in high wall sleeve openings (rough opening approx. 42-1/4 in wide x 16-1/4 in minimum high).
- Compatible with 265V commercial electrical circuits (239–292V operating range) via NEMA 7-20P plug, when paired with the required Amana PTSB4**E sub-base or PTPWHWK4 hardwire kit with PSHW04A disconnect.
- Not compatible with 115V household circuits.
- Not compatible with 230/208V circuits — the 230/208V version of this chassis is sold as model PTH123J.

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 (WS900E / WS900QW standard depth 14 in).
What breaker size and plug type does this unit require?
With the 2.5 kW electric heat installed, this configuration has an MCA of 12.2A and a maximum overcurrent protection (MOP) rating of 15A. It uses a NEMA 7-20P plug at 265V.
Can this be hardwired for 265V commercial applications?
Yes. This is a 265V unit and must be installed with an Amana brand sub-base (PTSB4**E series) or hardwire kit PTPWHWK4 with disconnect switch PSHW04A. Neither is included with the unit.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
[NEEDS VERIFICATION] Installer licensing requirements are not specified in the provided data. Refer to the manufacturer warranty document in the Resources tab for installation conditions affecting warranty validity.
