About the C-4 — Boiler, Hot Water Heating & Steam Fitting License
The C-4 Boiler, Hot Water Heating and Steam Fitting license authorizes contractors to install, maintain, and repair boilers, hot water heating systems, and steam fitting equipment. This specialized trade requires deep knowledge of pressure systems, safety protocols, and building codes. C-4 contractors work on both residential and commercial projects, from home radiant heating systems to large commercial boiler installations. Given the potential safety hazards of pressurized heating systems, it is critical to hire only licensed professionals for this type of work. California requires regular inspections of commercial boiler systems, making qualified C-4 contractors essential for building owners. When hiring, verify the contractor has experience with your specific type of system and ask about their emergency service availability.
About the C-7 — Low Voltage Systems License
The C-7 Low Voltage Systems license covers the installation, maintenance, and repair of systems that operate on low electrical voltage. This includes security alarms, fire detection systems, data and communication cabling, home automation, intercoms, CCTV surveillance, and structured wiring. As smart home technology and security needs continue to grow, C-7 contractors are increasingly in demand. Unlike C-10 electricians who work with standard electrical power, C-7 specialists focus on signal and data systems. This distinction is important because improper installation of low voltage systems can affect performance, void warranties, or create safety issues. When hiring a C-7 contractor, ask about their experience with your specific system type, whether they offer monitoring services, and if they stay current with rapidly evolving technology standards.
