Top notch mechanical contractor. Very professional.
Consider Pro Circuit Electric if...
- ✓ You need residential electrical work such as generator installation, pool lighting, automation systems, or exterior electrical projects that match their 25-year specialty
- ✓ You value specialized knowledge in Generac generator systems and backup power solutions for your home
- ✓ You're willing to verify liability coverage and confirm your homeowner's insurance covers contractor injuries given the lack of workers compensation
- ✓ You prioritize highly responsive service and direct owner involvement based on consistent customer feedback about accessibility
Consider Therma if...
- ✓ You need commercial mechanical work, HVAC duct manufacturing, or custom industrial fabrication rather than residential electrical services
- ✓ Your project involves medical gas systems, process equipment, or commercial plumbing installations in an industrial setting
- ✓ You require workers compensation coverage as a non-negotiable protection, though this would be for commercial projects outside residential electrical scope
- ✓ You need high-volume manufacturing capabilities or precision custom metal fabrication work
Questions to Ask Before Hiring
- → Ask Pro Circuit Electric specifically about their general liability coverage limits and confirm your homeowner's insurance policy covers contractor injuries on your property given the absence of workers compensation
- → Ask Therma directly whether they perform residential electrical work, as their experience and customer base appears entirely commercial and industrial
- → Ask Pro Circuit Electric for references from recent generator installation or residential electrical projects similar to yours
- → Ask both companies to clarify exactly which services they provide for residential properties versus commercial facilities
The Bottom Line
If you need residential electrical work, particularly generator installation, pool lighting, or home automation, Pro Circuit Electric is the appropriate contractor with 25 years of relevant residential specialization. Therma operates in a completely different market serving commercial and industrial mechanical needs. Before hiring Pro Circuit Electric, address the workers compensation gap by verifying their general liability coverage and confirming your homeowner's insurance protects you from contractor injury claims. Contact Therma only if you have commercial mechanical or fabrication needs, not for home electrical projects.

Frequently Asked Questions
You likely shouldn't unless you're unclear about what services each provides. Pro Circuit Electric handles residential electrical work like generators and lighting, while Therma manufactures HVAC ducts and does commercial mechanical work. If you need residential electrical services, Pro Circuit Electric is the relevant choice despite the workers comp concern.
It's a real liability concern. If a worker is injured on your property and the company lacks workers comp, you could be held financially responsible for medical costs and damages. Before hiring Pro Circuit Electric, verify they carry adequate general liability coverage and confirm your homeowner's policy provides protection. This is not a dealbreaker but requires due diligence.
Not if they don't actually perform residential electrical work. Therma's insurance is appropriate for their commercial mechanical projects, but you need a contractor with relevant residential electrical experience. Having proper insurance matters, but only if the contractor specializes in the work you need.
This comparison is only meaningful within the same specialty. Pro Circuit Electric's 25 years in residential electrical work means extensive experience diagnosing home electrical issues and handling generator complications. Therma's 9 years in commercial mechanical work is substantial for industrial projects but doesn't translate to residential electrical expertise.

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.
