- ✓ You need solar panel installation, battery storage, EV charging stations, or related electrical work—this is Synergy 768's core specialty with 12 years of focused experience
- ✓ Project predictability matters to you, as customers consistently report on-schedule completion and projects finishing within established budgets
- ✓ You value direct owner involvement in project planning and oversight, which customers frequently mention as a strength
- ✓ You're planning a complex installation requiring permitting and utility coordination with PG&E, areas where the company receives specific positive feedback
Consider Matrix HG if...
- ✓ You need HVAC maintenance, repair, or furnace installation rather than solar or electrical work
- ✓ You can obtain detailed, written estimates upfront and verify all charges before authorizing work to address the pricing transparency concerns evident in customer feedback
- ✓ The 23-year operational history provides some confidence in technical knowledge, though you should request the specific technician's background
- ✓ You're prepared to ask explicit questions about payment arrangements and cost breakdowns given multiple customer reports of unexpected charges
Questions to Ask Before Hiring
- → For Matrix HG: Request a detailed, itemized written estimate before any work begins and ask explicitly what circumstances would result in additional charges beyond the estimate
- → For Matrix HG: Ask which specific technician will work on your project and request their background, given the variability in customer experiences
- → For Synergy 768: If considering electrical work outside their solar specialty, ask for references from similar non-solar electrical projects
- → For both: Confirm the timeline for project completion and what guarantees exist if delays occur
The Bottom Line
If you need solar panels, battery storage, or EV charging installation, Synergy 768 is the clear choice with consistent feedback about on-time, on-budget delivery and strong owner involvement. If you need HVAC work, Matrix HG has the relevant 23-year experience, but the multiple reports of pricing transparency issues require you to protect yourself with detailed written estimates and explicit cost agreements before authorizing any work. These contractors serve fundamentally different home systems, so your project type should drive the decision. For solar and electrical energy systems, go with Synergy 768. For HVAC, Matrix HG is an option only if you secure ironclad pricing documentation upfront.

Frequently Asked Questions
You likely wouldn't unless you're evaluating options for completely different projects or considering bundled work on your home. These contractors serve fundamentally different systems. If you need solar panels or EV charging, Synergy 768 is the relevant choice. If you need heating and cooling work, Matrix HG would apply. The comparison only makes sense if you're vetting contractors for separate, unrelated projects.
Not necessarily. While 23 years demonstrates business survival, multiple customers reporting unexpected charges and poor cost communication represents a pattern that directly affects your financial risk. Experience matters less if the business practices create disputes. You can mitigate this by demanding detailed written estimates and explicit cost agreements before authorizing any work, but the pattern itself is a legitimate concern.
Synergy 768 is licensed for electrical work and customers mention some non-solar projects like floor conversion and air conditioning installation. However, their primary focus and most consistent feedback centers on solar, battery storage, and EV charging infrastructure. If you need general electrical work unrelated to energy systems, ask specifically for references from similar projects to ensure their expertise extends to your needs.
Customers specifically mention owner Ed Cotas being involved in consultations, explaining technical details, and providing project oversight. This typically means more consistent communication and accountability throughout the installation process. For complex solar or EV charging projects with permitting and utility coordination requirements, having direct access to the decision-maker often translates to faster problem resolution and clearer project updates.

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.
