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 electricians who need a 265V, per-room heating and cooling system with electric heat backup for cold-weather performance.
The PMH094J35AXXX is a 265V packaged terminal heat pump (PTHP) built for hospitality properties, multi-family additions, and commercial spaces that need self-contained, per-room comfort without central ductwork. It combines a heat pump compressor with a 3.7 kW electric heat strip for backup heating capacity in colder conditions, and it 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: Standard 42 in wide x 16-1/16 in high.
- Voltage: 265V (commercial-grade circuit; not a residential 115V or 230/208V unit).
- Total amperage with electric heat: 14.2A; MCA 17.9A; MOP 20A.
- Power cord/plug: NEMA 7-20P.
- Wall Sleeve and Exterior Architectural Grille are sold separately and are NOT included with this unit.
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits. The 230/208V version of this chassis is sold as model PMH093J — order that model instead if your building supply is 230/208V.
- 265V installation requires an Amana PTSB4**E sub-base or the PTPWHWK4 hardwire kit with PSHW04A disconnect switch (both sold separately).
- Not a drop-in replacement for non-standard or undersized sleeve openings.
On 265V installs, techs sometimes reuse a standard sleeve mounting job without re-checking pitch, because the electrical side (matching the 7-20P cord to the correct sub-base or hardwire disconnect) takes priority. But condensate drainage depends entirely on the sleeve, not the chassis. Set the sleeve with a 1/4-bubble pitch to the outside wall using a torpedo level before final fastening — this keeps condensate draining outward instead of pooling back against the interior drywall, which is what causes rot and mold callbacks six months later. On the electrical side, verify the receptacle or sub-base is rated for 265V and matches a 7-20P NEMA configuration before energizing the circuit; mismatched or field-modified plugs on 265V circuits are a direct NEC violation and a fire risk. Confirm both the sleeve pitch and the receptacle match before the drywall or exterior grille goes on — it's much harder to fix either one afterward.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit is designed to fit a standard 42 in x 16-1/16 in sleeve opening, but the sleeve itself (e.g., WS900E) ships as a separate item.
What breaker size and plug type does this unit require?
With the 3.7 kW electric heat strip installed, this configuration requires a Minimum Circuit Ampacity (MCA) of 17.9A and Maximum Overcurrent Protection (MOP) of 20A, using a 7-20P power cord/plug configuration at 265V.
Can this be hardwired for 265V commercial applications?
Yes. This is a 265V model. It must be installed using an Amana brand sub-base (PTSB4**E series) or the PTPWHWK4 hardwire kit with PSHW04A disconnect switch, both sold separately. It is not compatible with 115V or 230/208V circuits.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
265V hardwire or sub-base installations should be performed by a licensed electrician familiar with NEC receptacle and disconnect requirements. Exact warranty conditions related to installation 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 fits 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 dimensions.
