Top notch mechanical contractor. Very professional.
Consider Flores Electric if...
- ✓ You need residential electrical work such as panel upgrades, outlet installations, whole home rewiring, EV charger installation, or bringing older home electrical systems up to current code
- ✓ You value clear communication throughout the project, with detailed explanations about scope, pricing, and timelines from a contractor accustomed to working directly with homeowners
- ✓ You appreciate thorough cleanup practices and professional conduct on residential job sites, with a contractor who understands the unique concerns of having work done in an occupied home
- ✓ Your project requires coordination with local municipalities and utility companies for permitting, which Flores Electric routinely handles for panel upgrades and major electrical work
Consider Therma if...
- ✓ You operate a commercial or industrial facility requiring custom HVAC duct manufacturing, specialty ducting components, or process equipment fabrication rather than residential electrical services
- ✓ Your project involves mechanical contracting needs such as plumbing systems, medical gas installations, steam systems, or large-scale metal fabrication with precision requirements
- ✓ You need high-volume manufacturing capacity for custom metal components or specialty electrical gutters for commercial applications
- ✓ You're looking for a contractor with experience serving Silicon Valley industrial and commercial facilities rather than residential properties
Questions to Ask Before Hiring
- → Ask Therma directly if they perform residential electrical work and whether their team has experience with typical home electrical projects, as their business model focuses on commercial mechanical contracting
- → Ask Flores Electric about their specific experience with your type of electrical project and request references from similar residential work completed in the past year
- → Confirm with either contractor how they handle permitting and inspections for your specific project, as requirements differ significantly between residential electrical and commercial mechanical work
The Bottom Line
For residential electrical projects, choose Flores Electric without hesitation. Their entire business model centers on serving homeowners with the exact services you likely need: panel upgrades, rewiring, code compliance work, EV charger installations, and routine electrical repairs. Therma operates in a different sector entirely, focusing on commercial mechanical contracting and industrial fabrication. This isn't a close comparison requiring careful evaluation of trade-offs; it's a straightforward match between contractor specialization and homeowner needs. Contact Flores Electric for your residential electrical project.

Frequently Asked Questions
Therma holds a mechanical contractor license and specializes in HVAC duct manufacturing and industrial fabrication, not residential electrical work. For home electrical projects like panel upgrades, rewiring, or outlet installations, you need an electrical contractor like Flores Electric who specializes in residential services. Contact Therma directly if you have commercial mechanical needs rather than residential electrical work.
The licensure difference is less significant than the specialization gap. Both companies are experienced contractors, but those years were spent developing expertise in completely different areas. Flores Electric's seven years focused on residential electrical projects directly relevant to homeowner needs, while Therma's nine years built capabilities in commercial mechanical contracting and industrial fabrication.
Flores Electric is the appropriate choice for residential panel upgrades, as this work falls squarely within their specialization. They routinely coordinate permitting with local municipalities and utility companies for panel upgrades, and customers specifically mention 100 to 200 amp panel upgrades in their feedback. Therma's commercial mechanical focus does not align with typical residential electrical upgrade projects.
If you need commercial-grade HVAC duct manufacturing, custom metal fabrication for industrial equipment, or mechanical contracting services for a commercial property, Therma would be appropriate. For typical residential electrical needs like wiring, outlets, panels, lighting, or EV chargers, Flores Electric's residential electrical specialization makes them the clear match.

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.
