Make up Air Uncovered

Make up air units have grown popular in the hospitality industry as the no-duct work needed packaged terminal AC. When outside humidity drops around 55 degrees, make up air PTACs are great for high humidity regions to 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, with a variety of control and reheat options.​Often associated with the fit and function of rooftop units, make up air units 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 or the HVAC system cannot introduce fresh air. ​Many times they are added to 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.
