Consider Next Generation Electric if...
- ✓ You need residential electrical services like EV charger installation, panel upgrades, or generator repair in the Gilroy area
- ✓ You value responsive communication and educational explanations about your home's electrical system
- ✓ You're comfortable verifying your homeowner's insurance covers contractor injuries since workers comp isn't on file
- ✓ You want a contractor with weekend availability and flexible scheduling for home projects

- ✓ Your project involves medical gas systems, process equipment, or high-volume mechanical contracting work
- ✓ You need precision fabrication capabilities for specialty ducting components or custom electrical gutters
- ✓ You require a contractor with workers compensation insurance for commercial project compliance
Questions to Ask Before Hiring
- → Ask Next Generation Electric about liability coverage details and confirm your homeowner's policy covers contractor injuries on your property
- → Ask Therma directly whether they take residential projects, as their portfolio suggests commercial-only focus
- → Ask Next Generation Electric for references from recent residential projects similar to yours in scope and complexity
The Bottom Line
If you need residential electrical services—EV charger installation, panel upgrades, generator repair, or electrical troubleshooting—Next Generation Electric is your only viable option here, despite the workers comp concern that you'll need to address through liability verification. Therma serves commercial and industrial clients with mechanical contracting and custom fabrication needs, not homeowners with electrical projects. This isn't a close call based on quality or experience; it's simply a matter of finding the contractor who actually does the work you need done. Contact Next Generation Electric for home electrical work, and verify insurance coverage before signing any contract.

Frequently Asked Questions
Based on their profile, Therma specializes in commercial mechanical contracting and industrial HVAC fabrication, not residential electrical services. Their expertise is in manufacturing custom ductwork and process equipment for commercial facilities. If you need home electrical work, Next Generation Electric is the appropriate choice between these two.
If a worker is injured on your property and the contractor lacks workers compensation insurance, you could potentially be held liable for medical costs and damages. Before hiring Next Generation Electric, verify your homeowner's insurance covers contractor injuries, or ask them to provide proof of alternative coverage. This is a real financial risk that shouldn't be dismissed.
The experience comparison is irrelevant here because they work in completely different fields. Next Generation Electric's 13 years in residential electrical work matters for home projects, while Therma's 9 years in commercial mechanical contracting applies to industrial facilities. Choose based on which service you actually need, not the years-licensed number.
Next Generation Electric is the clear choice for residential EV charger installation. Customer feedback specifically mentions successful EV charging outlet installations at homes, and the company serves residential customers in Gilroy. Therma focuses on commercial mechanical systems, not residential electrical service calls.

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.
