Surplus PTAC units (Packaged Terminal Air Conditioners) are self-contained heating and cooling systems that install through an exterior wall, delivering room-by-room climate control without any ductwork. All components, including the compressor, evaporator coil, condenser coil, fans, and heating elements, are housed in a single chassis that slides into a standard wall sleeve, with the indoor side facing the room and the outdoor side venting through an exterior grille. PTACs are the standard climate control solution in hotels, assisted living facilities, hospitals, college dormitories, and multi-family housing, and are increasingly used in residential add-on spaces like guest suites, basements, and sunrooms where running new ductwork is impractical.

PTAC units use electric resistance heating. A coil heats up, and a fan distributes warm air into the room. These are reliable in all climates but use more electricity for heating than heat pump models. PTHP units (Packaged Terminal Heat Pumps) add a heat pump that reverses the refrigeration cycle to extract heat from outdoor air and move it inside, which is significantly more efficient than resistance heating; most PTHP units include a resistance backup strip for temperatures below approximately 40°F when heat pump efficiency drops. For climates with mild winters, a PTHP is the more energy-efficient choice; for consistently cold climates or installations where heating cost is a secondary concern, a standard PTAC with electric heat is straightforward and dependable.

PTACs are the standard choice wherever multiple rooms each need independent thermostat control without shared ductwork. Hotels, motels, assisted living facilities, hospitals, college dorms, and apartment buildings are the most common commercial applications. In residential settings, PTACs are a practical solution for spaces that are difficult to connect to a central HVAC system: finished basements, detached guest suites, sunrooms, converted garages, home offices, and accessory dwelling units. The key fit criterion is a single zone needing dedicated heating and cooling; for multi-room coverage from a single outdoor unit, a ductless mini split would be a more appropriate choice.

PTACs offer commercial-grade durability and an easily swappable chassis. A failed unit can be unplugged and replaced in the same sleeve in under an hour, which is why hotels and multi-family operators favor them; mini splits are more energy-efficient and quieter but require professional installation of refrigerant lines and a separate outdoor condenser. Window air conditioners are the simplest to install but block natural light, offer limited or no heating capability, and are the least efficient of the three; PTACs provide both heating and cooling in one permanent through-wall unit without sacrificing window space. For residential buyers, a mini split is often the better long-term efficiency investment for a primary living space; PTAC units are the stronger choice for rental rooms, guest suites, and commercial applications where durability, fast replacement, and room-level control matter more than peak efficiency.

PTAC cooling capacity is measured in BTUs per hour; a widely used starting point is approximately 20 BTUs per square foot of conditioned space, though actual requirements vary with insulation quality, ceiling height, window area, and sun exposure. Common room sizes map roughly as follows: 9,000 BTUs for rooms up to 400 square feet, 12,000 BTUs for 400 to 550 square feet, and 15,000 to 17,000 BTUs for larger rooms and suites up to 700 to 800 square feet. Oversizing is as problematic as undersizing. An oversized unit cycles off before adequately removing humidity, leaving the room feeling damp; the Surplus City team at 765-482-7000 can help confirm sizing for a specific application.

Most residential and light commercial PTAC units require a 208/230-volt dedicated circuit; larger commercial applications and some hotel installations use 265/277-volt systems. It’s important to confirm the available voltage at the installation site before ordering. Amperage varies by model and heating output: 15-amp units are common for cooling-focused or lower heat output applications, while 20- and 30-amp versions deliver more electric heating capacity for colder climates. New installations require both a properly sized wall opening and a dedicated electrical circuit; an electrician should handle the circuit work, after which the chassis slides into the sleeve and plugs in.

Yes, the wall sleeve is a separate steel frame permanently installed in the wall opening that remains in place when the PTAC chassis is removed or replaced; most manufacturers use a standard 42-inch-wide by 16-inch-tall sleeve, meaning a new unit often fits an existing sleeve even when switching brands. In addition to the sleeve, a matching exterior grille and a power cord or hard-wire kit (depending on installation type) are typically required; Surplus City carries wall sleeves and related PTAC accessories alongside unit inventory. For replacement installations, measure the existing sleeve before ordering to confirm compatibility. A matching chassis slides directly in without requiring wall modification.

All surplus PTAC units and PTHP units at Surplus City Liquidators are brand-new and have never been installed. No units sourced from hotel renovations, no refurbished or reconditioned inventory. Surplus City purchases directly from manufacturers in large quantities, which is the source of the pricing advantage; every unit arrives in original manufacturer packaging, in excellent condition, and ready for installation. Property operators sourcing multiple units can order with confidence that each unit arrives without any prior service history.

PTAC and PTHP units ship nationwide. Customers can choose their preferred shipping method at checkout, where shipping costs are automatically calculated. For large or multi-unit orders, customers are welcome to contact the Surplus City team at 765-482-7000 to discuss bulk shipping rates and logistics. Customers can also pick up orders directly at any of Surplus City’s warehouse locations.
