Detailed Breakdown

1. Credentials Are Non-Negotiable

AC installation in California requires a licensed contractor with a C-20 HVAC license. Hiring a licensed pro means they’ve passed state exams, carry insurance, and follow California’s building codes. Always verify a contractor’s license through the CSLB database.

Beyond licensing, a reputable installer should provide:

• General liability insurance
  
• Workers’ compensation coverage (if applicable)
  
• A list of recent local installations and customer references
  

If a contractor hesitates to show this documentation, consider it a deal-breaker.

2. Know the Local Rules

Los Angeles has very specific rules when it comes to AC installation:

• A mechanical HVAC permit is required for most installations or replacements
  
• Installations must comply with Title 24 energy efficiency standards
  
• Post-install inspections ensure the unit is installed correctly and safely
  

Any installer who tells you permits are “optional” or unnecessary is either uninformed—or intentionally skipping steps. That can cause issues with insurance, safety inspections, or home resale.

Smart HVAC professionals (like those offering HVAC services understand that compliance isn’t just about paperwork—it’s about protecting your home.
