Commercial HVAC costs in California vary significantly based on system type, building size, and service complexity. Routine maintenance contracts typically run $150–$400 per unit per year. Emergency service calls average $300–$800 for diagnosis and basic repairs. System replacements for rooftop units range from $8,000–$35,000 depending on tonnage.

What commercial HVAC certifications should I look for in California?
Look for NATE (North American Technician Excellence) certified technicians, which validates hands-on HVAC competency. For refrigerant handling, EPA Section 608 certification is federally required.
