Top notch mechanical contractor. Very professional.
Consider Nci Electric if...
- ✓ You need residential electrical work like panel upgrades, outlet installation, or home rewiring
- ✓ You're installing an EV charger at your home and want a contractor experienced with residential code requirements
- ✓ You're undertaking a home remodel and need an electrician who works patiently with homeowners through extended projects
- ✓ You want a contractor with a track record of thorough safety inspections who identifies hazards in older homes
Consider Therma if...
- ✓ You operate a commercial or industrial facility needing custom HVAC ductwork manufacturing
- ✓ You require precision metal fabrication for mechanical systems, electrical gutters, or specialty ducting components
- ✓ You're managing a commercial project needing comprehensive mechanical contracting including plumbing, medical gas, or steam systems
- ✓ You need high-volume manufacturing capabilities for mechanical components rather than residential service work
Questions to Ask Before Hiring
- → Before contacting Therma for any residential project, ask directly if they perform residential work—their business model focuses on commercial and industrial clients
- → If considering Nci Electric, ask for references from projects similar to yours, particularly if you have an older home that may need safety upgrades
- → Ask Nci Electric about their typical project timeline and scheduling process to ensure alignment with your needs
The Bottom Line
If you're a homeowner needing electrical work, choose Nci Electric—Therma doesn't serve the residential market. Nci Electric has a decade of experience with residential electrical projects, maintains proper insurance and bonding, and receives consistent praise for professional home service and thorough safety work. Therma is an excellent commercial mechanical contractor, but their expertise in industrial HVAC manufacturing and commercial systems isn't relevant to residential electrical needs. Contact Nci Electric for your home project.

Frequently Asked Questions
No. Therma is a commercial mechanical contractor specializing in HVAC duct manufacturing and industrial fabrication work. They do not perform residential electrical services. Their customer base consists of commercial and industrial facilities in Silicon Valley, not homeowners.
This appears to be a matching error. These companies serve completely different markets with different specializations. If you need residential electrical work, Nci Electric is the relevant contractor. If you need commercial mechanical systems or duct manufacturing, Therma would be appropriate.
Nci Electric focuses on residential electrical services for homeowners. Their project history includes panel replacements, EV charger installations, and home remodeling electrical work—not the commercial mechanical systems and industrial fabrication that Therma specializes in.
Not in this case. While both have approximately 9-10 years of licensed experience, they've developed expertise in completely different fields. Their similar tenure doesn't make them comparable options for any single project type.

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.
