Top notch mechanical contractor. Very professional.
Consider Corporate Electric if...
- ✓ You need electrical work such as panel upgrades, rewiring, lighting installation, or electrical repairs
- ✓ You value the diagnostic capability that comes from 20 years navigating California electrical codes and evolving safety standards
- ✓ Your project is residential rather than commercial in scope
- ✓ You're comfortable proceeding with limited review history and plan to request references directly
Consider Therma if...
- ✓ You need commercial mechanical work, particularly custom HVAC ductwork or specialty metal fabrication
- ✓ Your project involves industrial or commercial facilities requiring process equipment fabrication
- ✓ You need medical gas systems, plumbing fitting, or steam systems for a commercial property
- ✓ You want documented customer feedback showing technical capabilities and manufacturing quality for commercial-scale projects
Questions to Ask Before Hiring
- → For Corporate Electric: Can you provide references from recent residential electrical projects similar to mine, given the limited online review history?
- → For Therma: Do you handle residential projects, or is your focus primarily commercial and industrial clients?
- → For both: What is your typical timeline from initial consultation to project completion for a project of my scope?
- → For both: Will the owner or a dedicated project manager be my point of contact throughout the work?
The Bottom Line
If you need electrical work, Corporate Electric is your only appropriate choice from these two contractors—Therma doesn't do electrical. If you need commercial mechanical systems or custom metal fabrication, Therma is the specialist with documented customer satisfaction in that niche. For residential homeowners needing electrical service, proceed with Corporate Electric but request references directly given the limited review history. If you need residential HVAC work, contact Therma to confirm they handle residential projects, or look for a residential-focused HVAC contractor instead.

Frequently Asked Questions
You typically wouldn't unless your project requires both trades, such as a major renovation involving electrical upgrades and HVAC work. For standard residential electrical projects, Corporate Electric is the appropriate choice. For commercial mechanical systems or custom metal fabrication, Therma is the specialist.
The available data shows Therma focuses primarily on commercial and industrial clients, with customer feedback mentioning Silicon Valley facilities and high-volume manufacturing capabilities. If you have a residential HVAC need, you should ask Therma directly whether they take residential projects or if their focus is exclusively commercial.
Only if you need electrical work, since that's Corporate Electric's specialty. The 20 years of licensure demonstrates sustained capability in electrical services, but the lack of review data means you'll need to request references directly. You cannot use Therma's mechanical contracting reviews to evaluate Corporate Electric's electrical work—they're different trades entirely.
Yes, both maintain workers compensation insurance and identical $25,000 bonds, which protects you if work isn't completed as agreed. Both have active California contractor licenses. From a liability and financial protection standpoint, they're equivalent—the difference lies in their trade specialization and track records.

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.
