Make up air units have grown popular in the hospitality industry as the no-duct work needed packaged terminal AC. When outside humidity is around 55 degrees, these PTAC units are great for high humidity regions. They help avoid the stale smell in rooms that can result.

Designed to treat 100% outside air, the unit supply’s either cold or room-neutral air. It comes with a variety of control and reheat options.​ Often associated with the fit and function of rooftop units, make up air devices do not necessarily need to be on the rooftop, but instead can function normally inside the mechanical room of the property.
​
Also known as fresh air units, the best candidates for make up air are rooms where the air cannot be circulated. They are also effective for situations where the HVAC system cannot introduce fresh air. ​These air conditioning units introduce fresh air into a space which a heat pump is unable to do on its own. It’s important to note that operating costs will increase with this application due to the constant treating of new air when compared to an HVAC system that can provide a larger energy savings using recirculated air.
