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...

Consider Cinnamon Energy Systems if...
- ✓ You're planning a solar installation and want to integrate heat pump HVAC as part of a comprehensive home electrification project, avoiding coordination headaches between multiple contractors
- ✓ Your project requires extensive electrical work, panel upgrades, or utility coordination that naturally accompanies solar integration
- ✓ You prefer working with a Los Gatos-based contractor with established permitting relationships throughout Santa Clara County for renewable energy projects
- ✓ You're interested in battery backup systems like Tesla Powerwall alongside HVAC upgrades to create an integrated energy solution
Consider Prime Air Conditioning if...
- ✓ Your primary need is HVAC service, repair, or replacement without any solar component, and you want a contractor whose entire business focuses on heating and cooling systems
- ✓ You value ongoing maintenance relationships with biannual inspections and the ability to call for emergency furnace or AC repairs when equipment fails
- ✓ You're located in Gilroy or Morgan Hill and prefer working with a local contractor with high owner involvement and established community presence
- ✓ You want a contractor experienced in traditional HVAC systems, ductwork installation, and both conventional and heat pump technologies without the solar specialization
Questions to Ask Before Hiring
- → If choosing Cinnamon for HVAC-only work, ask how many standalone heat pump projects they complete annually versus solar-integrated installations
- → If choosing Prime for a heat pump tied to future solar plans, ask about their experience sizing systems for homes planning solar integration and whether they coordinate with solar contractors
- → Ask both contractors about equipment brands they install, warranty coverage, and whether they perform their own service work or subcontract maintenance
- → Request references from projects matching your specific scope—solar-integrated HVAC for Cinnamon, or standalone HVAC system work for Prime
The Bottom Line
This comparison only makes sense if you're considering a heat pump or mini-split installation—the one service area where these fundamentally different contractors overlap. If you're installing solar panels, battery backup, or pursuing comprehensive home electrification, Cinnamon Energy Systems is the clear choice with relevant specialization. If you need HVAC repair, traditional system replacement, or ongoing heating and cooling service without solar components, Prime Air Conditioning's dedicated HVAC focus and maintenance infrastructure better serves those needs. The decision is straightforward: match the contractor's specialization to your actual project scope. Don't hire a solar contractor for HVAC-only work, and don't expect an HVAC specialist to navigate utility interconnection for solar installations.

Frequently Asked Questions
Prime can install heat pumps sized appropriately for your home, but their expertise is in HVAC performance rather than solar integration planning. If solar is part of your near-term plans, ask Prime how they approach sizing for homes that may add solar, and consider whether coordinating with a solar contractor upfront through Cinnamon might simplify future integration. Heat pumps work fine without solar, but electrical panel capacity and system sizing benefit from coordinated planning.
Cinnamon can handle heat pump and mini-split installations, but their business model centers on solar energy projects. If you have no solar plans, Prime's dedicated HVAC focus, emergency repair capabilities, and ongoing maintenance programs likely better match your needs. Cinnamon's value proposition increases substantially when HVAC integrates with broader electrification goals.
Prime Air Conditioning explicitly offers maintenance plans with biannual inspections and monthly billing options, with customer feedback highlighting their service responsiveness. Cinnamon's review patterns focus on installation project completion rather than ongoing service relationships. If regular HVAC maintenance and rapid repair response matter to you, Prime's service-oriented business model provides clearer infrastructure for long-term support.
Both serve Santa Clara County, so either can reach your home. Location becomes relevant for service speed and local relationships—Prime's Gilroy base and high owner involvement may benefit Morgan Hill and South County residents seeking quick service calls, while Cinnamon's Los Gatos location reflects their established permitting relationships throughout the broader county for solar projects. Consider which contractor is more accessible for your specific service needs.

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.
