Customer Reviews
Cinnamon Energy Systems
I started thinking about solar last year, but it was not until this year when I became serious. I talked to as many as 6 companies who serve San Jose area, and in the end, I decided to go with Cinnamo...

We are quite happy with our solar power system installed by Cinnamon Energy Systems. We are fortunate enough to have south and west facing roofs and were able to work with them to install a system of...
Aircom Mechanical
If you have a commercial building you should get professional service from Aircom Mechanical.
Consider Cinnamon Energy Systems if...
- ✓ You're installing solar panels, battery backup systems like Tesla Powerwall, or heat pump HVAC systems and want a contractor whose primary business focuses on these specific technologies
- ✓ You value documented residential customer feedback showing consistent communication, professional installation crews, and clean worksite practices throughout multi-week solar projects
- ✓ Your project requires complex permitting and utility coordination in Santa Clara County, where Cinnamon has extensive established history
- ✓ You're planning system expansions or future electrification work and want a contractor customers reference hiring for multiple projects
Consider Aircom Mechanical if...
- ✓ You have a commercial mechanical project rather than residential work, where Aircom's focus appears to align better with available evidence
- ✓ You're considering a very basic mechanical repair like thermostat replacement and prioritize working with the longest-tenured contractor regardless of specialization
- ✓ You prefer a company that's been continuously licensed since 1986 and value maximum operational longevity over documented residential solar experience
Questions to Ask Before Hiring
- → Ask Aircom Mechanical directly about their residential solar and battery installation experience, number of residential solar projects completed in the past two years, and whether they can provide recent residential solar references
- → Ask Aircom whether solar and heat pump work represents a primary business line or occasional side work, and who would perform the installation if you're not getting their most experienced crew
- → Ask Cinnamon about typical project timelines from contract signing through final utility permission to operate, and how they handle any issues discovered during electrical panel assessment
- → Ask both companies about their warranty terms for equipment and installation workmanship, and who handles service calls if issues arise after installation
The Bottom Line
For residential solar panel installation, battery backup systems, or heat pump HVAC work, Cinnamon Energy Systems is the clear choice based on available data. Their 13 years of documented specialization in exactly these technologies, extensive positive customer feedback on residential installations, and proven expertise with permitting and utility coordination directly matches what homeowners need. Aircom Mechanical's impressive 39-year history demonstrates business longevity, but the lack of residential solar project visibility suggests this isn't their primary focus. Unless your direct conversation with Aircom reveals substantial residential solar experience not reflected in available data, choose Cinnamon for solar and electrification projects.

Frequently Asked Questions
Not necessarily for residential solar work. Aircom's licensing began in 1986, well before modern solar technology became mainstream, and available data shows minimal residential solar project visibility. Cinnamon's 13 years of licensing aligns with the modern solar era and includes documented expertise in current technologies like Tesla Powerwall, inverter systems, and utility interconnection processes that define today's solar installations. For solar projects, relevant specialization matters more than general longevity.
The available data suggests Aircom primarily serves commercial clients rather than residential customers. This isn't inherently problematic—many contractors successfully focus on commercial work—but it does mean you're selecting a company without visible track record in residential solar or heat pump projects. If you're a homeowner planning solar installation, you'd want to confirm directly that Aircom has substantial residential solar experience despite limited online feedback in that area.
Their contractor license classification may allow it, but available data doesn't demonstrate residential solar as a core business line. Cinnamon's project list specifically includes solar arrays, Tesla Powerwall integration, inverter replacements, and electrical panel upgrades with extensive customer feedback on these installations. Before hiring Aircom for solar work, ask directly about their residential solar volume, crew experience with your specific equipment, and relationships with solar equipment suppliers and local utility companies for interconnection.
Yes, if you have a commercial mechanical project or if your research reveals that Aircom has substantial residential solar experience not reflected in available review data. Their 39-year operational stability is meaningful for ongoing commercial relationships. However, for typical residential solar, battery, or heat pump installations, Cinnamon's documented specialization and extensive residential customer feedback provide more evidence they're set up to handle your specific project type efficiently.

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.
