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...

HVACerz and the owner Barsin provide extremely high quality service! We needed a new heat pump and called HVACerz, in part because of the good reviews on Yelp and Google. We were not disappointed in...
Prompt, Professional, Clean and Efficient. Couldn't ask for anything more.
Consider Cinnamon Energy Systems if...
- ✓ You're installing solar panels and want heat pump installation coordinated as part of a whole-home electrification project with unified permitting and system design
- ✓ Your project requires battery backup integration, electrical panel upgrades, or utility interconnection coordination that benefits from extensive permitting history
- ✓ You prefer working with a contractor who has 13 years of experience navigating Santa Clara County's solar regulatory environment and can handle complex system engineering
- ✓ You value comprehensive project planning and detailed technical explanations over rapid installation timelines
Consider HVACerz if...
- ✓ You need pure HVAC work without any solar component and want the fastest possible service for emergency repairs or system failures
- ✓ Your heat pump or mini-split installation is straightforward without electrical panel upgrades or battery integration requirements
- ✓ Same-day or next-day availability matters because your current system has failed or you're facing extreme weather conditions
- ✓ You prefer working directly with a smaller operation where owner involvement provides consistent communication and hands-on attention throughout the project
Questions to Ask Before Hiring
- → Ask Cinnamon about typical timelines from contract signing to installation completion and whether HVAC-only projects without solar integration fit their current scheduling priorities
- → Ask HVACerz whether they coordinate with solar contractors if you later decide to add solar, and if they handle electrical panel upgrades needed for heat pump installations
- → Ask both contractors for references from projects similar to yours, specifically heat pump installations with or without solar integration depending on your needs
The Bottom Line
Your decision should be driven entirely by project scope, not contractor quality, since both are properly licensed and insured. Choose Cinnamon Energy Systems if you're installing solar panels, battery backup, or complex home electrification projects where their 13 years of permitting experience and system integration expertise justify longer timelines and comprehensive planning. Choose HVACerz if you need standalone HVAC work, emergency repairs, or heat pump installation without solar integration, where their rapid response times, single-day completions, and hands-on service model deliver exactly what heating and cooling projects require. Don't hire a solar specialist for pure HVAC work if speed matters, and don't hire an HVAC specialist for solar integration.

Frequently Asked Questions
Yes, both can install heat pumps independently. HVACerz specializes in standalone HVAC installations and typically completes them within a single day. Cinnamon can handle heat pump installations but primarily works on projects integrated with solar and battery systems, so ask whether HVAC-only work fits their current scheduling and pricing structure.
For a straightforward heat pump replacement with adequate existing electrical capacity, the experience gap matters less than service model differences. However, if your installation requires electrical panel upgrades, complex ductwork modifications, or coordination with solar equipment, Cinnamon's additional years navigating permitting and electrical integration provide meaningful advantages that newer contractors are still developing.
HVACerz demonstrates significantly faster response times based on customer feedback, with same-day and next-day service frequently mentioned. Cinnamon's projects involve more extensive planning phases including system design, permitting, and utility coordination, resulting in longer timelines from initial contact to installation. If speed is your primary concern and solar isn't involved, HVACerz is the clearer choice.
This could provide continuity if you're confident about adding solar within a year or two, since they'd already understand your electrical setup and HVAC configuration. However, don't pay a premium or accept longer timelines for HVAC work based solely on potential future solar installation. Ask Cinnamon directly whether they offer any advantage for customers who return for solar after initial HVAC 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.
