When your facility depends on strong ventilation, a makeup air unit (MAU) keeps indoor air balanced, clean, and comfortable. These systems draw in fresh outdoor air, temper it, and replace the air that’s exhausted through hoods, vents, or industrial fans—crucial for restaurants, warehouses, and manufacturing spaces across the Carolinas.
At Top Mechanical Service, we deliver complete commercial makeup air unit services, including installation, repair, and maintenance, for businesses throughout Charlotte, NC, and Fort Mill, SC. Our licensed and certified technicians ensure your MAU system runs safely, efficiently, and in compliance with ventilation codes.
