What commercial HVAC certifications should I look for in Connecticut?
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. In Connecticut, commercial work typically requires a state contractor license. Manufacturer certifications from Carrier, Trane, or Lennox indicate authorized service capability.
