Frequently Asked Questions
Therma is a mechanical contractor, not an electrical contractor—they specialize in HVAC, plumbing, and custom metal fabrication for commercial/industrial clients. If you need electrical work, Boss Electric is the appropriate choice. Therma does not appear to focus on residential projects based on their documented expertise.
Limited review history makes it difficult to identify a definitive pattern, but some customers have reported communication challenges. Before hiring, ask Boss Electric about their communication process, typical response times, and how they handle project updates. Request recent references who can speak to their responsiveness.
Only if you have a commercial facility needing both electrical and mechanical work. For residential electrical needs, Boss Electric is the relevant option. For commercial mechanical systems or custom metal fabrication, Therma is appropriate. These contractors serve different trades and markets entirely.
They're equally experienced within their respective specialties, but those specialties don't overlap. Nine years of electrical contracting experience doesn't translate to mechanical systems expertise, and vice versa. Choose based on which trade matches your actual project requirements, not just years in business.

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.
