Frequently Asked Questions
No, these are separate licensed trades in California. Sanchez Electric holds an electrical contractor license, while Therma holds a mechanical contractor license. If your project requires both electrical and mechanical work, you'll need to hire separate contractors for each trade.
Based on their service description and customer feedback, Therma appears to focus primarily on commercial and industrial mechanical projects rather than residential work. If you're a homeowner, you should ask Therma directly whether they take residential projects before proceeding.
The experience gap reflects both different founding dates and different trades. For electrical work specifically, 34 years means Sanchez has encountered virtually every type of electrical problem, code change, and project complication. This depth of experience becomes valuable when diagnosing hidden issues or handling older electrical systems.
Both are properly licensed, insured, and bonded for their respective trades in California. The question isn't about qualifications but about trade specialization—one does electrical work and the other does commercial mechanical systems. Your project type determines which contractor is appropriate, not their relative qualifications.

Detailed Comparison
We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.
Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.
- Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
- Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
- Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
- Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.
Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
