Questions to Ask Before Hiring
- → Ask Therma directly if they serve residential clients, as their profile suggests commercial-only focus
- → Ask Purplefox for references from projects similar to yours, given their one year of independent licensing
- → Ask about each company's typical project size and client type to confirm alignment with your needs
- → Ask Purplefox how they handle unexpected complications given their newer status versus asking Therma about their residential service capabilities
The Bottom Line
Unless you manage a commercial facility needing mechanical contracting or custom HVAC fabrication, Purplefox Electrical is your only relevant option for residential electrical work. Therma's nine years of experience applies to commercial mechanical projects and industrial manufacturing, not home electrical services. If you're a homeowner in Campbell needing electrical upgrades, solar installation, or panel work, choose Purplefox based on their residential focus and responsive service model. If you manage commercial property requiring ductwork or mechanical systems, contact Therma directly about your industrial project needs.

Frequently Asked Questions
Therma's profile indicates they specialize in commercial mechanical contracting and industrial HVAC fabrication, not residential electrical work. You should contact them directly to confirm, but their expertise and customer feedback center entirely on commercial facilities and custom manufacturing rather than home services.
For standard residential electrical work like panel upgrades, circuit installations, and solar systems, one year of licensed operation provides adequate experience, particularly given Purplefox's compliance with workers comp and bonding requirements. However, for complex troubleshooting or older homes with unusual wiring, you may want additional references from similar projects.
Therma is clearly better suited for commercial mechanical work with nine years of experience in HVAC duct manufacturing, custom fabrication, and commercial systems. Purplefox focuses on residential electrical services and does not offer the mechanical contracting or fabrication capabilities that commercial HVAC projects require.
For straightforward residential electrical projects, Purplefox's one year of licensing combined with positive customer feedback on workmanship and professionalism is sufficient. The more significant issue is that Therma offers mechanical services for commercial clients, not residential electrical work, making the experience comparison irrelevant for most homeowners.

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.
