Consider Carnahan Electric if...
- ✓ Your electrical problem is complex or has stumped other contractors, as Carnahan has a track record of successfully diagnosing issues others miss
- ✓ You want full insurance protection, including workers compensation coverage that shields you from liability if someone is injured during the work
- ✓ You value direct owner communication and relationship-building, as the owner personally answers calls and stays involved
- ✓ You need generator service or solar system diagnostics, where Carnahan has specific documented expertise
Consider Holderby Electric if...
- ✓ You need emergency electrical service late in the evening and value contractors who respond to urgent calls outside business hours
- ✓ You prioritize punctual arrivals and efficient completion of straightforward electrical work
- ✓ You're comfortable verifying workers compensation coverage directly or accepting the liability risk if coverage isn't available
- ✓ Your project is relatively routine electrical diagnostics or repair work rather than complex troubleshooting
Questions to Ask Before Hiring
- → For Holderby Electric: Ask explicitly about liability coverage and whether they carry workers compensation insurance now, and confirm with your homeowner's insurance whether you're covered if a contractor's worker is injured on your property
- → For both companies: Ask for references from projects similar to yours, particularly if your electrical issue is complex or involves systems like generators or solar
- → For Holderby Electric: Ask how they handle complications during projects and whether they subcontract any work, since subcontractor injuries could also create liability issues
The Bottom Line
Carnahan Electric is the safer choice for most homeowners, offering twice the experience, full insurance protection including workers compensation, and documented ability to solve complex electrical problems. The workers compensation gap at Holderby Electric creates real liability risk that could cost you far more than any project savings. Carnahan's 44 years and owner-involved approach provide additional confidence for technical problem-solving. If you're considering Holderby despite the insurance gap, confirm current workers comp status directly, verify your homeowner's policy covers contractor injuries, and ensure your project is straightforward rather than diagnostic work. For complex electrical issues, generator service, or maximum protection, Carnahan Electric is the clear choice.

Frequently Asked Questions
For routine repairs or installations, both companies have sufficient experience. The difference becomes meaningful when electrical problems are hard to diagnose or involve older homes with undocumented wiring changes. Carnahan's 44 years translates to having seen more unusual situations, which customers specifically mention when describing complex problems they solved that others couldn't. If your issue is straightforward, Holderby's 24 years is more than adequate.
If a worker from Holderby Electric is injured on your property, you could be directly liable for their medical bills, lost wages, and other damages. Many homeowner's policies exclude or limit coverage for contractor injuries, leaving you personally exposed. With Carnahan's workers compensation coverage, their insurance handles worker injuries regardless of fault. Before hiring Holderby, call your insurance agent to understand your specific coverage and risk exposure.
Both respond quickly to urgent needs and arrive punctually. The difference appears in technical depth: Carnahan customers specifically describe complex diagnostics, generator expertise, and solving problems other electricians missed, while Holderby feedback focuses on efficient completion of electrical diagnostics and repairs without mentioning unusual problem-solving. For emergency power restoration, either works; for mysterious electrical issues requiring investigation, Carnahan shows more documented capability.
Owner-answered phones typically mean faster decision-making, consistent communication, and accountability directly to the person responsible for the business reputation. Customers won't get passed between office staff and field crews. For complex projects requiring judgment calls or custom solutions, direct owner access often speeds up the process and ensures decisions align with your priorities rather than getting filtered through employees.

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.
