- → Ask Therma directly if they handle residential electrical projects or if their focus remains commercial mechanical work
- → Request recent project examples that match your scope to ensure the contractor has relevant experience
- → Verify which company can pull the necessary permits for your specific project type in your jurisdiction

Wooding Electric brings 32 years of electrical expertise with proven residential service quality, punctuality, and thorough diagnostics. Therma excels at commercial mechanical contracting and custom metal fabrication but doesn't serve the residential electrical market.

Frequently Asked Questions
Therma holds a mechanical contractor license and specializes in industrial HVAC duct manufacturing and custom metal fabrication for commercial facilities. Their project portfolio shows no residential electrical work. For electrical projects, Wooding Electric is the appropriate choice with 32 years of electrical contracting experience.
You likely wouldn't unless you're confusing mechanical contracting with electrical work. Therma serves commercial and industrial clients needing custom metal fabrication, specialty ductwork, and mechanical systems. If you have a commercial facility needing custom ductwork or fabrication alongside electrical work, you'd need to hire both companies for their respective specialties.
The experience gap matters less than the fundamental trade difference. Wooding Electric's 32 years provides deep electrical expertise for diagnosing hidden issues and handling complex installations. Therma's 9 years is solid for their mechanical contracting work, but they serve an entirely different market with different technical requirements.
For electrical work during renovation—panel upgrades, new circuits, lighting—Wooding Electric is the clear choice with extensive residential experience and consistent feedback on communication and efficiency. Therma would only be relevant if your renovation involves custom metal fabrication or industrial-grade mechanical systems, which is uncommon in residential projects.

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.
