Top notch mechanical contractor. Very professional.
Consider Mc Lean Electric if...
- ✓ You need electrical services such as panel upgrades, circuit installation, outlet work, or electrical troubleshooting for your home or commercial property
- ✓ You value the experience depth that comes with 23 years of navigating electrical code changes and complex residential wiring scenarios
- ✓ Your project involves older electrical systems where diagnosing hidden issues requires extensive field experience
- ✓ You're looking for a local Campbell-based contractor familiar with Santa Clara County permitting and inspection requirements
Consider Therma if...
- ✓ You need commercial HVAC duct manufacturing or custom metal fabrication rather than standard residential electrical work
- ✓ Your project involves specialty ducting components, medical gas systems, or industrial mechanical equipment that requires precision fabrication capabilities
- ✓ You're managing a commercial or industrial facility in Silicon Valley requiring high-volume manufacturing capacity for mechanical components
- ✓ You need plumbing, steam systems, or process equipment fabrication services beyond typical residential scope
Questions to Ask Before Hiring
- → Ask Mc Lean Electric for specific references from recent electrical projects similar to yours, given the limited review history available
- → Ask Therma directly whether they handle residential projects or if their focus on commercial and industrial work means your project falls outside their typical scope
- → Confirm with either contractor how long their current crew has been working together and what percentage of their work matches your project type
- → Ask about timeline expectations, as commercial-focused contractors may have different scheduling patterns than residential-focused ones
The Bottom Line
For homeowners needing electrical work—panel upgrades, rewiring, circuit additions, or electrical repairs—Mc Lean Electric is the appropriate choice as a veteran electrical contractor with 23 years of experience. Therma operates in a different specialty entirely, focusing on commercial mechanical contracting and industrial fabrication. Unless you're managing a commercial property requiring custom HVAC duct manufacturing or specialty mechanical fabrication, Therma's strengths won't align with typical homeowner needs. Choose based on which trade your project actually requires, then evaluate the contractor within that specialty.

Frequently Asked Questions
In most cases, you wouldn't—these companies serve different trades. This comparison only makes sense if you're uncertain about the scope of your project or if you have a commercial property needing both electrical and specialized mechanical work. For standard residential needs, the trade specialty should guide your choice before other factors matter.
Based on available data, Therma focuses on commercial mechanical contracting, custom duct manufacturing, and industrial fabrication rather than typical residential HVAC service. Their praised work involves specialty components and high-volume manufacturing for commercial clients. You should ask them directly whether residential projects align with their current business focus.
Yes, for complex electrical projects. Twenty-three years means Mc Lean Electric has worked through multiple electrical code revisions and encountered a broader range of problem scenarios, particularly valuable when diagnosing issues in older homes or managing complicated panel upgrades. However, this advantage only matters if you're comparing within the same trade.
Limited review history means you have less public feedback to assess service patterns, communication style, and project completion reliability. Compensate by asking for multiple recent references, verifying those references directly, and asking specific questions about timeline commitments and how they handle unexpected complications during electrical work.

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.
