What Makes MDTECH a Licensed C-20 Contractor?
In California, the C-20 license is the gold standard for HVAC work valued at over $500. It requires passing both a Trade Exam and a Law & Business Exam, demonstrating technical expertise, safety knowledge, and legal compliance.
Here is what our status as a licensed Air Conditioning Contractor means for you:
1. Verified Expertise and Skill
Our licensing confirms we meet the state requirement of having at least four years of journey-level experience in the trade. This expertise translates directly to accurate diagnostics, efficient repairs, and professionally executed installations.
System Mastery: We are authorized and skilled to work on all aspects of your system, including warm-air heating, ventilation, air conditioning units, heat pumps, ductwork, and thermostats.
Refrigerant Compliance (EPA 608): Our technicians are EPA certified to handle and manage regulated refrigerants safely and legally, preventing environmental damage and ensuring your system operates at peak efficiency.
2. Financial and Consumer Protection
When you hire an unlicensed contractor, you assume all risk. Choosing MDTECH provides crucial legal and financial safeguards:
Contractor’s Bond: We maintain the required contractor’s bond (currently $25,000 minimum in California) with the CSLB, offering you a layer of protection should we fail to meet contract terms.
Workers’ Compensation: We carry the necessary insurance to protect our workers, ensuring you are not liable for any job-site injuries.
Liability Insurance: Our liability coverage protects your property against any accidental damage that might occur during service or installation.
3. Guaranteed Quality of Work
As a licensed contractor, we adhere to the strict California Building Codes and industry best practices. We ensure every job—from installing a new high-efficiency AC unit to repairing a furnace—is done correctly the first time.
| MDTECH Service | Contractor Requirement | Your Benefit |
| New AC Installation | Proper sizing, load calculation, and permitting | Maximum energy efficiency and cooling power. |
