This is a wall-sleeve heat pump system 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, with electric heat backup for cold snaps.
The PMH093J25AXXX is a DigiAIR heat pump PTAC built for hospitality rooms, additions, and multi-family units where ducted HVAC isn't practical. It combines a heat pump compressor with a 2.5/2.1 kW electric heat strip for backup capacity in colder conditions, and it's 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.
- Wall sleeve opening: industry-standard 42 in wide x 16-1/16 in high (standard depth 14 in) — Wall Sleeve NOT included, sold separately.
- Exterior Architectural Grille — NOT included, sold separately.
- Voltage: 230/208V. Factory power cord: NEMA 6-15P, UL 484 LCDI cord (applies to all units under 250V).
- Minimum Circuit Ampacity: 14.1A. Maximum Overcurrent Protection: 15A.
- Not compatible with 115V circuits.
- Not for 265V hardwire installations. The 265V commercial version of this chassis is the PMH094J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A — none of that hardware applies to or ships with this 230/208V unit.
- Not a drop-in fit for non-standard or custom sleeve openings — verify existing sleeve dimensions before ordering a replacement chassis.
On heat pump PTACs like this one, condensate forms on the coil during both cooling and defrost cycles, and a sleeve that's level or pitched inward will send that water into the wall cavity instead of outside. Set the wall sleeve with a 1/4-bubble pitch toward the exterior using a torpedo level before securing it in the rough opening — this keeps condensate draining outward and out of the drywall, subfloor, and insulation. Confirm the sleeve extends a minimum of 1/4 inch beyond the exterior wall face per the framing diagram, and re-check level side-to-side separately from the drainage pitch. This is standard property management practice for hospitality PTAC installs and prevents callback claims for water stains or mold remediation months after install.
Key Benefits
- Heat pump operation delivers 7,800/7,600 BTU of heating (230V/208V) without relying on electric heat alone, reducing operating cost in moderate climates.
- 2.5/2.1 kW electric heat strip provides backup heating capacity (8,500/6,800 BTU) when outdoor temperatures drop below heat pump efficiency range.
- EER of 12.4/12.5 and COP of 3.6/3.6 indicate efficient cooling and heat pump performance for a PTAC-class system.
- Fresh air ventilation CFM of 25-35 supports make-up air exchange for occupied rooms.
- R-32 refrigerant used in this chassis.
- Factory-installed 6-15P cord and LCDI device (UL 484) simplify plug-and-play installation on a standard 15A, 230/208V circuit — no hardwiring required.

Compatibility & Fitment
- Compatible with 230/208V circuits via a factory-installed NEMA 6-15P plug on a 15A circuit.
- Fits standard 42-inch wide x 16-1/16-inch high wall sleeve openings, standard 14-inch sleeve depth (WS900E / WS900QW series).
- Not compatible with 115V circuits.
- Not for 265V hardwire applications — the 265V version of this chassis is the PMH094J, and it requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, none of which apply to this 230/208V model.
- Wall Sleeve and Exterior Architectural Grille are sold separately — confirm sleeve compatibility before ordering.
- Not a drop-in fit for non-standard or custom sleeve openings.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis fits the industry-standard 42-inch wide x 16-1/16-inch high opening, with a standard 14-inch sleeve depth (WS900E / WS900QW series).
What breaker size and plug type does this unit require?
This unit ships with a factory-installed 6-15P power cord. Minimum Circuit Ampacity is 14.1A and Maximum Overcurrent Protection is 15A, so it's designed for a 15-amp, 230/208V circuit.
Can this be hardwired for 265V commercial applications?
No. This model is a 230/208V unit and is not rated for 265V. The 265V commercial version of this chassis is the PMH094J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, none of which are included or applicable here.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
Amana's warranty documentation should be consulted for the exact installation requirements. Refer to the Resources (System Manuals and Warranty) tab above for the full terms.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis is designed for the industry-standard 42-inch wide x 16-1/16-inch high wall sleeve opening. It is not a drop-in fit for non-standard or custom sleeve openings.
