Walk into ten older warehouses in Georgia and at least seven will have HVAC systems that don't match the current operation. The building changed; the equipment didn't.
Common mismatches
- Original spec was for storage, current use is pick-and-pack
- Mezzanines added without HVAC updates
- Office buildouts pulling air from warehouse zones
- More headcount than the original ventilation plan
Symptoms of an undersized system
- Short cycling RTUs
- Hot zones near roll-up doors and dock areas
- High humidity inside the conditioned space
- Climbing energy bills with no operational changes
The fix
A proper load calculation, updated for current use, is the starting point. From there, the answer is usually a mix of additional units, destratification fans, and better envelope sealing — not a full system replacement.
