This is a wall-sleeve heat pump air conditioner and heater for hotel rooms, apartments, or coastal properties where central ductwork isn't available. It's built for property managers and homeowners near saltwater environments who need self-contained, per-room heating and cooling with added corrosion protection.
The PMH073J25CXXX is Amana's DigiAIR heat pump PTAC platform, built around a chassis rated for cooling, heat pump heating, and auxiliary electric heat in a single self-contained unit. The Feature Code "C" designation on this model adds seacoast corrosion protection to the coil and cabinet construction, making it suited to coastal hospitality properties, marina-adjacent condos, or any installation within reach of salt air. This unit 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 required: industry-standard 42 in wide x 16-1/16 in high. Rough framing opening: approximately 42-1/4 in wide x 16-1/4 in minimum high.
- Voltage: 230/208V. Compatible with 230/208V circuits only.
- Amperage with electric heat installed: total 11.2/10.1A; MCA 14.1A; MOP (breaker size) 15A.
- NEMA Plug Type: 6-15P, factory-installed LCDI power cord per UL 484 (applies to this sub-250V unit).
- Wall Sleeve is NOT included and must be purchased separately (e.g., Amana WS900E, WS900QW, or seacoast-rated WS900SC).
- Exterior Architectural Grille is NOT included and must be purchased separately (SGK, AGK, or PGK series).
- Not compatible with 115V circuits.
- Not suitable for 265V commercial installs. The 265V commercial sibling of this chassis is model PMH074J, which requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A (both sold separately) — do not attempt to hardwire this 230/208V model as a substitute.
- Not a drop-in fit for non-standard or custom sleeve openings — verify dimensions against the sleeve model before ordering.
Pro-Installer Tip: Sleeve Pitch and Seacoast Drainage
On seacoast installs, condensate drainage gets overlooked because installers focus on the corrosion-resistant coil and assume the sleeve handles water the same way everywhere. It doesn't — salt-air humidity loads push more condensate volume through the sleeve than an inland install, and any back-pitch toward the room will wick water into the drywall and framing over time, even with a seacoast-protected chassis. Set the sleeve with a 1/4-bubble pitch toward the outside wall, level side-to-side, and confirm it with a torpedo level before securing — this matches Amana's own framing diagram guidance for this chassis family. Document the pitch check in your commissioning notes; it's a standard property-management best practice for hospitality PTAC/PTHP rollouts and protects you if a water-intrusion claim comes up later.
Key Benefits
- Heat pump operation delivers 6,200/6,100 BTU/h of heating from the compressor before the electric heat strip engages, reducing reliance on resistance heat in moderate climates.
- EER of 12.6/12.7 and COP of 3.6/3.6 place this unit's efficiency data on record for side-by-side comparison against other PTHP chassis.
- Built-in fresh air ventilation (25-35 CFM) supports make-up air needs in tightly sealed guest rooms.
- Seacoast corrosion protection (Feature Code C) targets coil and cabinet longevity in coastal or high-salinity environments.
- Single-stage 2.5/2.1 kW electric heat backup is sized to the 230/208V circuit without requiring a 20A or 30A upgrade.
- R-32 refrigerant is specified for this chassis (catalog note 7).

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit is designed to install into an industry-standard 42 in x 16-1/16 in wall sleeve opening, such as the Amana WS900E or WS900QW, or the seacoast-rated WS900SC sleeve.
What breaker size and plug type does this unit require?
With the 2.5/2.1 kW electric heat strip installed, this unit has a Minimum Circuit Ampacity (MCA) of 14.1A and requires Maximum Overcurrent Protection (MOP) of 15A. It ships with a factory-installed 6-15P power cord for a standard 230/208V, 15A NEMA receptacle.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V model and is not rated for 265V circuits. If you need a 265V commercial unit on this chassis, the sibling model PMH074J is designed for that voltage and requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, both sold separately.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
[NEEDS VERIFICATION] - installer licensing requirements for warranty validity are not confirmed in the provided specification data. Refer to the warranty PDF in the Resources tab for exact terms.
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, with a rough framing opening of approximately 42-1/4 in wide x 16-1/4 in minimum high. It is not a drop-in fit for non-standard or custom sleeve openings without verifying dimensions first.
