This is a wall-sleeve heat pump and backup-heat air conditioning unit 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 heating and cooling on a 265V circuit.
The HEH124J35AXXX is a 265V packaged terminal heat pump (PTHP) built for hospitality corridors, multi-family retrofits, and additions where a heat pump's efficiency is preferred over straight electric-resistance heat. It pairs a heat pump compressor rated at 11,600 BTU/h heating with a 3.7 kW electric heat strip for backup heat below the compressor's practical operating range. AHRI-rated performance figures (EER 11.6, COP 3.4) are drawn from the manufacturer catalog. 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: industry-standard 42 in wide x 16-1/16 in high (Amana WS900E / WS900QW series or compatible).
- Voltage: 265V commercial circuit. Operating range 239V minimum / 292V maximum.
- Total heater load: 3.7 kW, 14.2A, MCA 17.9A, MOP 20A.
- Power cord: 7-20P plug configuration.
- Wall Sleeve is NOT included and is sold separately.
- Exterior Architectural Grille is NOT included and is sold separately.
- 265V models require an Amana sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit with PSHW04A disconnect switch — sold separately, not included with the chassis.
- Not compatible with 115V circuits.
- Not compatible with 230/208V circuits — that voltage class is served by the sibling chassis HEH123J, not this unit.
- Not a drop-in fit for non-standard or custom-depth sleeve openings; confirm sleeve model before ordering.
On 265V hospitality retrofits, techs often reuse an existing sleeve without re-checking the pitch, and that's where trouble starts. The technical friction: a sleeve that's level or pitched the wrong direction lets condensate run back toward the drywall instead of out to the exterior weep. Over a cooling season, that moisture migrates into the wall cavity and rots framing long before anyone notices a drip inside the room. The long-term prevention is simple — set the sleeve with a 1/4-bubble pitch to the outside, checked with a torpedo level across the sleeve rail before you fasten it permanently. The expert validation: this is the same pitch tolerance called out in Amana's own framing diagram for this chassis, not a field guess. The professional standard: verify the sleeve extends a minimum of 1/4 inch beyond the exterior wall face per the framing spec, and document the pitch check in your commissioning notes — property managers doing NEC-compliant 265V rollouts across multiple units will ask for this record during warranty claims.
Key Benefits
- Heat pump compressor delivers 11,600 BTU/h heating with a COP of 3.4, reducing reliance on resistance heat in moderate outdoor temperatures.
- 3.7 kW backup electric heat strip covers colder conditions when the heat pump alone can't meet load.
- Dehumidification rating of 1.7 pints/hr supports guest comfort in humid climates.
- Fresh air ventilation adjustable from 65-95 CFM for make-up air in occupied rooms.
- R-32 refrigerant.
- Meets or exceeds ASHRAE 90.1 efficiency standards.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit is designed to fit an industry-standard 42-inch wide by 16-1/16-inch high sleeve opening, such as the Amana WS900E or WS900QW series.
What breaker size and plug type does this unit require?
This 265V configuration with the 3.7 kW electric heat strip requires a Minimum Circuit Ampacity (MCA) of 17.9A and Maximum Overcurrent Protection (MOP) of 20A. It ships with a 7-20P power cord.
Can this be hardwired for 265V commercial applications?
Yes. All 265V Amana PTAC/PTHP models must be installed with an Amana brand sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit paired with the PSHW04A disconnect switch. These are sold separately and are required for code-compliant 265V installation.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
[NEEDS VERIFICATION] - installation labor requirements are not specified in the provided catalog 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 fits the industry-standard 42-inch wide by 16-1/16-inch high sleeve opening. It is not a drop-in fit for non-standard or custom-depth openings without selecting the corresponding Amana deep or custom sleeve variant.
