Warehouse HVAC & Ventilation for High-Desert Distribution
Warehouse HVAC is a different problem than office HVAC. High ceilings, thin insulation, dock doors constantly opening — cooling every cubic foot is often uneconomical. We spec targeted cooling zones plus destratification and high-volume evaporative to keep workers within OSHA limits.
Services we provide
- • High-volume evaporative cooling
- • Targeted rooftop or split-system cooling for workspaces
- • Destratification fans (HVLS)
- • Loading-dock heaters
- • Warehouse office space HVAC
Equipment we install and service
- • Portacool evaporative units
- • Big Ass Fans HVLS (12–24 ft diameter)
- • Modine gas unit heaters
- • Standard commercial split systems for offices
Key challenges in this vertical
- • Cooling entire warehouse is rarely economical
- • OSHA / Cal-OSHA heat illness prevention requires action >80°F
- • Roof insulation R-values often below R-19
Why DC Air
- • Hybrid mechanical + evaporative designs that meet Cal-OSHA at 30% of the cost of full mechanical cooling
- • Financing structured for e-commerce fulfillment budgets
- • Dock-door air-curtain integration
Frequently asked questions
Do we really need to cool the whole warehouse?
Rarely. Most operators zone-cool the pick/pack area, use HVLS destratification everywhere, and add spot evaporative near stationary workstations. Full-warehouse cooling costs 3–5x more for marginal comfort gain.
What are Cal-OSHA heat requirements?
Employers must provide water, shade, cool-down rest, and specific procedures once outdoor temp hits 80°F. Indoor rules apply once workplace temp exceeds 87°F. Fines start at $18,000 per violation.
Do HVLS fans really work?
Yes — a 20-ft HVLS fan covers 20,000 sq ft and moves ~85,000 CFM, giving a perceived 6–10°F cooling effect through air movement alone.
