This is a wall-sleeve heat pump and air conditioner for hotel rooms, apartments, additions, or offices where central ductwork isn't available. It's built for property managers and homeowners who need self-contained, per-room heating and cooling with electric heat backup for cold-weather performance.
The HEH123J35AXXX is a 230/208V packaged terminal heat pump (PTHP) built for hospitality properties, multi-family housing, and room additions that need independent heating and cooling without ductwork. It pairs a heat pump compressor with a 3.5/3.0 kW electric heat strip for backup heating capacity when outdoor temperatures drop below the heat pump's effective range, 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 (industry-standard PTAC dimension).
- Voltage: 230/208V. Min 197V / max 253V operating range.
- Total amps with electric heat: 15.5A (230V) / 14.1A (208V). MCA 19.5A, MOP 20A.
- Power cord/plug: NEMA 6-20P, factory-installed, with LCDI protection per UL 484 (applies to units under 250V).
- Wall Sleeve is NOT included and is sold separately.
- Exterior Architectural Grille is NOT included and is sold separately.
- Not compatible with 115V circuits.
- Not compatible with 265V commercial applications — the 265V sibling chassis (HEH124J) requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, none of which apply to or are included with this 230/208V unit.
- Not a drop-in replacement for non-standard or custom-depth sleeve openings — verify existing sleeve model before ordering as a replacement chassis.
On retrofit jobs, the most common callback on this chassis isn't the compressor — it's condensate weeping into the drywall below the sleeve. Wall sleeves need a 1/4-bubble pitch to the outside on the side-to-side level, confirmed with a torpedo level, not eyeballed off the framing. Skipping that pitch lets condensate migrate along the sleeve bottom and wick into the interior wall cavity over a heating-cooling cycle season, which shows up as stained drywall or mold complaints six months later, not on install day. Also double-check that the receptacle is a genuine NEMA 6-20R — a 6-20P cord forced into a mismatched 6-15R or 6-30R receptacle is both an NEC violation and a fire risk that will fail inspection. This is standard practice on any hospitality PTAC swap-out where the general contractor pre-installed sleeves before the electrical rough-in was finalized.
Key Benefits
- Heat pump operation delivers 11,100/10,900 BTU/h of compressor-based heating (230V/208V) before the electric heat strip engages, reducing electric heat runtime and operating cost compared to heat-strip-only PTAC units.
- 3.5/3.0 kW electric heat backup (230V/208V) maintains room temperature when outdoor conditions fall below the heat pump's effective range.
- EER of 11.8/12.0 and COP of 3.4/3.4 (230V/208V) provide measurable efficiency benchmarks for side-by-side comparison against other PTHP chassis.
- Built-in fresh air ventilation (65-95 CFM) supports make-up air requirements in sealed hospitality rooms.
- Rated dehumidification of 1.7 pints/hour at high fan speed for guest comfort in humid climates.
- R-32 refrigerant charge, a lower-GWP alternative used across this chassis family.

FAQ
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This unit fits the industry-standard 42 in x 16-1/16 in PTAC sleeve opening (e.g., WS900E, WS900QW, and related Amana sleeve models), but the sleeve and exterior grille are not part of this listing.
What breaker size and plug type does this unit require?
This 230/208V configuration with 3.5/3.0 kW electric heat requires a Minimum Circuit Ampacity (MCA) of 19.5A and Maximum Overcurrent Protection (MOP) of 20A. It ships with a factory-installed 6-20P power cord for plug-and-play connection to a matching NEMA 6-20R receptacle.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V model and is not rated for 265V circuits. The 265V commercial sibling of this chassis, HEH124J, requires an Amana sub-base (PTSB4**E series) or hard-wire kit PTPWHWK4 with disconnect switch PSHW04A, none of which are included with this 230/208V unit.
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 PTAC sleeve opening. Confirm your existing sleeve model before ordering if replacing an older unit, since non-standard or custom-depth sleeves may not be compatible.
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 specified in the provided source files. Refer to the warranty document in the Resources tab for exact terms.
