This is a wall-sleeve air conditioner and electric heater built for hotel rooms, apartments, additions, or any room without central ductwork. It's a self-contained, per-room climate control unit for property managers and homeowners who need reliable cooling and heat in a single chassis.
The PTC073J35AXXX is a standard-model PTAC (Packaged Terminal Air Conditioner) with a single-stage electric heat strip, sized for hospitality rooms, additions, and multi-family units where ductwork isn't practical. It uses R-32 refrigerant and 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: industry-standard 42 in wide x 16-1/16 in high (e.g., WS900E, WS900QW series).
- Voltage: 230/208V. Valid operating range 197V minimum to 253V maximum.
- Amperage with electric heat installed: 15.5A/14.1A total (230V/208V); MCA 19.5A; MOP 20A.
- Power cord: factory-installed NEMA 6-20P plug with LCDI device per UL 484 (applies to all units under 250V).
- Wall Sleeve NOT included — sold separately.
- Exterior Architectural Grille NOT included — sold separately.
- Not compatible with 115V circuits.
- Not compatible with 265V sub-base or hard-wire installations; the 265V commercial sibling on this chassis is the PTC074J.
- Not a drop-in fit for non-standard sleeve openings outside 42 in x 16-1/16 in.
The most common callback on PTAC installs isn't the electrical — it's water intrusion behind the drywall from a sleeve that was set dead level instead of pitched. Set the sleeve level side-to-side, then pitch it toward the outside wall by about a 1/4-bubble reading on a Torpedo Level so condensate drains outdoors instead of back into the wall cavity. Confirm the sleeve extends a minimum of 1/4 inch beyond the outside wall surface before securing it, per the framing diagram tolerances. On the electrical side, verify the receptacle is a genuine NEMA 6-20R matched to the unit's factory 6-20P cord — don't force-fit a 6-15R receptacle onto a 20A-rated appliance. This is standard property-management best practice for avoiding both water damage claims and NEC receptacle-mismatch violations during inspection.

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 sleeve opening, such as the WS900E or WS900QW series.
What breaker size and plug type does this unit require?
With the 3.5/3.0 kW electric heat strip installed, this unit requires an MCA of 19.5A and a maximum overcurrent protection (MOP) of 20A. It ships with a factory-installed 6-20P power cord for a NEMA 6-20R receptacle on a 230/208V circuit.
Can this be hardwired for 265V commercial applications?
No. This is a 230/208V model. It is not rated for 265V and does not use the Amana sub-base or hard-wire kit required for 265V units. If you need a 265V commercial unit on this chassis, look at the PTC074J sibling model.
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 spec data. Refer to the manufacturer warranty document 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-inch wide x 16-1/16-inch high wall sleeve opening. It is not a drop-in fit for custom or non-standard sleeve openings.
