Commercial HVAC differs from residential in scale, complexity, and requirements. Here's what Bay Area business owners should know.
Commercial vs. Residential HVAC
Key Differences - Larger capacity equipment - More complex controls - Different maintenance needs - Stricter regulations - Higher reliability requirements
Common Commercial Systems - Rooftop units (RTUs) - Split systems (larger) - VRF/VRV systems - Packaged units - Chiller systems (large buildings)
Small Business Common Systems
Rooftop Units (RTUs) Most common for small commercial: - Self-contained on roof - Heating and cooling in one - Easy service access - Various sizes available
Split Systems Similar to residential but larger: - Indoor and outdoor components - Good for limited roof access - Flexible installation
Ductless/VRF Growing in popularity: - Multiple indoor units - Individual zone control - High efficiency - Good for varied spaces
Maintenance Requirements
More Frequent Than Residential - Monthly filter checks - Quarterly professional visits (minimum) - Annual comprehensive inspection - Documentation for compliance
What Maintenance Includes - Filter changes - Belt inspection - Electrical checks - Refrigerant verification - Thermostat calibration - Safety inspections
Why Maintenance Matters More - Business continuity - Customer comfort - Employee productivity - Energy costs higher - Compliance requirements
Energy Considerations
Commercial Energy Costs - Higher usage = bigger bills - Demand charges add costs - Time-of-use rates impact - Efficiency matters more
Efficiency Upgrades - Programmable/smart controls - Variable speed equipment - Energy management systems - Regular maintenance - LED lighting (reduces cooling load)
Common Small Business Scenarios
Retail Stores - High traffic ventilation needs - Consistent customer comfort - Display/product considerations
Restaurants - Kitchen exhaust requirements - Makeup air needs - High cooling loads - Health department compliance
Offices - Individual comfort zones - Meeting room challenges - After-hours setback - Air quality priorities
Medical/Dental - Strict temperature requirements - Air quality regulations - Equipment cooling needs
Choosing a Commercial Contractor
Look For - Commercial experience - EPA certified technicians - Proper licensing - 24/7 emergency service - Maintenance plans available - Good references
Questions to Ask - Experience with your building type? - Response time for emergencies? - Maintenance plan options? - Energy efficiency services?
Bay Area Commercial Considerations
Title 24 Compliance - Stricter than residential - Required for most work - Impacts equipment choices
Local Codes - Fire department requirements - Health department (food service) - Building department permits
Climate Benefits - Mild climate = lower costs than many areas - Natural ventilation opportunities - Economizer systems work well
Emergency Planning
Minimize Downtime - Have contractor relationship established - Know emergency contact numbers - Consider backup equipment - Plan for temporary solutions
Documentation - Keep maintenance records - Document equipment details - Note warranty information - Have service history accessible
Cost Management
Budget Planning - Maintenance: $1,000-$5,000+ annually - Emergency repairs: Budget contingency - Replacement planning: Know equipment age
Reducing Costs - Preventive maintenance (reduces emergency calls) - Energy efficiency upgrades - Smart scheduling/controls - Employee training (thermostat use)
Commercial HVAC is an essential business expense. Proper planning and maintenance protects your investment and your business.
