Questions to Ask Before Hiring
- → Confirm your project type first: does it require electrical work (Sanchez) or mechanical systems work (Therma)?
- → For Sanchez Electric: ask about typical response times for your specific project type and whether they have experience with your particular electrical needs
- → For Therma: ask whether they handle projects at your scale, as their focus appears to be commercial/industrial rather than small residential jobs
- → Request references from projects similar to yours in scope and complexity to verify the contractor handles your specific work type regularly
The Bottom Line
This comparison requires you to first identify your project trade. If you need electrical work—panel upgrades, wiring, circuits, lighting—Sanchez Electric is your clear choice with 34 years of proven experience and quick response times for both residential and commercial clients. If you need mechanical systems work—HVAC duct manufacturing, custom fabrication, plumbing, or specialty industrial systems—Therma is the relevant contractor. These companies don't compete for the same projects; they serve entirely different trades with different licensing and expertise. Identify whether your project is electrical or mechanical first, then contact the appropriate contractor.

Frequently Asked Questions
No, these are separate licensed trades. Sanchez Electric is licensed for electrical work only, while Therma is licensed for mechanical contracting. If your project requires both electrical and mechanical systems, you'll need to hire separate contractors for each trade or find a general contractor who can coordinate both.
Based on their profile, Therma focuses primarily on commercial and industrial mechanical work, particularly custom fabrication and specialty systems. For standard residential HVAC work, they may not be the right fit. Ask them directly if they service residential projects and whether they have residential references available.
Sanchez Electric's 34 years versus Therma's 9 years represents significant operational history, but this matters most within the same trade. The experience gap means Sanchez has encountered more electrical scenarios and complications. However, since they work in different trades entirely, the more important factor is matching your project type to the right contractor specialty.
You would need both contractors for a comprehensive facility project. Sanchez Electric would handle electrical panels, circuits, and lighting systems while Therma would address HVAC ductwork and mechanical systems. Coordinate scheduling between them or hire a general contractor to manage both trades, ensuring electrical and mechanical work is properly sequenced.

How We Compare Contractors
License Verification
All license data is sourced from official California CSLB records and verified regularly.
Review Analysis
Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.
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.
