Commercial HVAC Guide for Bay Area Small Businesses

Commercial HVAC for small businesses requires different considerations than residential systems. Understanding these differences helps you make better decisions for your business.

Commercial vs. Residential HVAC

Key Differences: Capacity: Commercial spaces often need more tonnage per square foot due to higher occupancy, equipment heat loads, and commercial kitchen demands. Duty Cycle: Business HVAC runs more hours daily, requiring commercial-grade equipment designed for extended operation. Zoning: Multiple zones for different areas (office, retail, storage) are common in commercial applications. Ventilation: Codes require more fresh air per occupant in commercial spaces.
