This is a wall-sleeve heat pump 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 heat backup for colder days.
The PMH153J50AXXX is Amana's DigiAIR heat pump PTAC (PTHP) platform, built for hospitality rooms, multi-family units, and additions where a self-contained heating and cooling system replaces central ductwork. This unit uses a heat pump compressor for both cooling and primary heating, backed by a 5.0/4.1 kW electric heat strip for cold-weather operation when heat pump capacity alone isn't sufficient. Performance ratings referenced here align with Amana's published catalog data and ASHRAE 90.1 compliance. 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: Standard 42 in wide x 16-1/16 in high (industry-standard PTAC sleeve dimension).
- Voltage: 230/208V. Voltage window per Amana spec: minimum 197V / maximum 253V.
- Total electric heat amps: 22.1A (230V) / 20.0A (208V). MCA: 27.6A. MOP: 30A.
- Power cord: factory-installed 6-30P plug, requiring a NEMA 6-30R receptacle on a dedicated 30A circuit.
- This 230/208V unit ships with an LCDI (Leakage Current Detection Interrupter) power cord per UL 484, standard on all units under 250V.
- Wall Sleeve is NOT included — it must be ordered separately (see WS900E, WS900QW, WS900SC, and other sleeve options).
- Exterior Architectural Grille is NOT included — order separately (SGK, AGK, or PGK grille series).
- Not compatible with 115V circuits.
- Not for 265V hardwire-only sub-base applications — this unit is a standard 230/208V factory-cord unit, not a 265V hardwire configuration.
- Not a drop-in replacement for non-standard or custom wall sleeve openings outside 42 in x 16-1/16 in.
The most common callback on a PTHP install traces back to the wall sleeve, not the chassis itself. When a sleeve is set dead-level side-to-side but flat front-to-back, condensate from the heat pump's cooling cycle pools at the indoor lip instead of draining outdoor, and over months that moisture wicks into the surrounding drywall and framing. Set the sleeve with a 1/4-bubble pitch toward the exterior using a torpedo level before securing it — this matches Amana's own framing guidance for the WS900 series sleeves. On the electrical side, confirm the receptacle is a NEMA 6-30R matched to this unit's factory 6-30P cord; a mismatched or improvised receptacle on a 30A circuit is both an NEC Article 210 violation and a fire-risk item that property managers should flag during any turnover inspection.
Key Benefits
- Heat pump operation delivers 13,900/13,700 BTU/h of primary heating (230/208V) with a COP of 3.0/3.1, reducing reliance on resistance heat in moderate climates.
- 5.0/4.1 kW electric heat strip provides backup heating capacity (17,100 BTU/h at 230V, 14,000 BTU/h at 208V) for colder conditions.
- EER of 10.2/10.5 on the cooling side supports efficient per-room climate control.
- Fresh air intake (25-35 CFM) allows for make-up air ventilation without a separate system.
- Meets or exceeds ASHRAE 90.1 efficiency standards.
- R-32 refrigerant used in this chassis.

FAQ
Is the wall sleeve included with this unit?
No. This PTHP requires an industry-standard 42 in x 16-1/16 in wall sleeve, which is sold separately. Amana offers several sleeve models (WS900E, WS900QW, WS900SC, and others) depending on your seacoast or acoustic needs.
What breaker size and plug type does this unit require?
This 230/208V unit with the 5.0/4.1 kW heat strip has an MCA of 27.6A and requires a 30A circuit (MOP 30A). It ships with a factory-installed 6-30P power cord, and a NEMA 6-30R receptacle is required.
Can this be hardwired for 265V commercial applications?
No. This model is a 230/208V unit and is not designed for 265V hardwire applications. 265V configurations require a dedicated Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, which do not apply to this 230/208V unit.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
Amana's published warranty coverage is 1-Year Repair/Replace and 5-Year Parts Limited Warranty. Full installation requirements and any professional-installation conditions for warranty validity 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 wide x 16-1/16 in high wall sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings.
Warranty & Registration
This unit carries Amana's published 1-Year Repair/Replace warranty and 5-Year Parts Limited Warranty. Exact terms — including any distinctions between residential and commercial hospitality usage — are detailed in the manufacturer warranty document available in the "Resources (System Manuals and Warranty)" Tab above. Review that document before install if this unit will see commercial or hospitality-grade usage, since duty cycles in those settings can carry different terms than residential use.
