Moisture at a construction site warrants serious attention, particularly because most building materials absorb moisture. As a result, a common construction drying solution includes the use of an on-site HVAC system in an attempt to maintain ideal relative humidity levels. The problem with this approach is that HVAC units are meant to condition air so the occupants inside feel comfortable. Using an HVAC system for a different reason increases the appliance’s load, causing unnecessary wear and tear. It’s simply the wrong tool for the task.
