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 that heats efficiently until outdoor temperatures drop, then leans on its electric heat strip as backup.
The PMH123J25AXXX is an Amana DigiAIR heat pump PTAC (PTHP) built for hospitality corridors, additions, and multi-family units where per-room climate control replaces central ductwork. Cooling and heat pump performance data reflect the 230/208V dual-voltage rating shown on the unit's chassis specifications. 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.
- Wall sleeve opening: Standard 42 in wide x 16-1/16 in high (industry-standard PTAC sleeve size).
- Voltage: 230/208V — compatible with 230V or 208V single-phase circuits.
- Total amps with electric heat: 11.2/10.1A; MCA 14.1A; MOP (max breaker/fuse) 15A.
- Power cord/plug: 6-15P, factory-installed with LCDI device per UL 484 (applies because this unit operates under 250V).
- Wall Sleeve is NOT included and must be ordered separately (e.g., WS900E, WS900QW, or related sleeve models).
- Exterior Architectural Grille is NOT included and must be ordered separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits.
- Not for 265V hardwire-only installations — that application requires the commercial sibling chassis PMH124J with an Amana sub-base (PTSB4**E) or hard-wire kit PTPWHWK4 and disconnect PSHW04A.
- Not a drop-in fit for non-standard or custom sleeve openings outside 42 in x 16-1/16 in.
The technical friction on any PTAC/PTHP retrofit is condensate drainage through the wall sleeve, not the electrical hookup. Framing crews often set the sleeve dead level because it "looks right," but a level sleeve traps condensate against the interior wall and lets it wick into the drywall over months, causing rot and mold behind the unit long after the crew is gone. Pitch the sleeve 1/4 bubble toward the outside wall — verify it with a torpedo level set lengthwise on the sleeve rail before securing it — so gravity carries condensate out through the drain path instead of back into the room. This is standard practice in property management PTAC turnovers: confirm sleeve pitch on every unit swap, not just new construction, since sleeves shift over years of thermal cycling.
Key Benefits
- Heat pump operation (10,600/10,400 BTU/h heating) reduces reliance on electric heat strip in moderate outdoor temperatures, lowering per-room energy costs versus heat-strip-only PTACs.
- COP of 3.3/3.3 indicates efficient heat pump performance relative to straight electric resistance heat.
- EER of 11.3/11.5 supports ASHRAE 90.1 compliance for commercial specification.
- Fresh air intake (25-35 CFM) supports make-up air ventilation in sealed hospitality rooms.
- 2.5/2.1 kW auxiliary electric heat strip provides backup heating capacity when outdoor ambient drops below the heat pump's effective range.
- R-32 refrigerant charge, per manufacturer catalog note.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis fits the industry-standard 42 in wide x 16-1/16 in high sleeve opening (WS900E, WS900QW, and related Amana sleeve models).
What breaker size and plug type does this unit require?
This configuration uses a 6-15P power cord plug, with an MCA of 14.1 amps and a maximum overcurrent protection (MOP) rating of 15 amps. It ships with a factory LCDI power cord per UL 484, since it operates under 250V.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V unit and is not rated for 265V operation. The 265V commercial version of this chassis is the Amana PMH124J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
The manufacturer's exact installation and licensing requirements are detailed in the warranty documentation. Refer to the Resources (System Manuals and Warranty) Tab above for full terms before installation.
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.
