Alfredo was professional and courteous, and so was the previous person who came out for quote. Modern Air does a great job with their client communications, and their cost is reasonable.
Consider Cinnamon Energy Systems if...
- ✓ You're installing solar panels, adding battery backup like Tesla Powerwall, or upgrading your electrical panel to support renewable energy systems
- ✓ Your project involves complex permitting, utility interconnection agreements, and coordination with local building departments where established relationships matter
- ✓ You're pursuing home electrification and need a contractor experienced in both the solar generation side and compatible heat pump HVAC installations
- ✓ You value detailed system design and engineering work with thorough explanations of technical specifications throughout the installation process
Consider Modern Air if...
- ✓ You need furnace or air conditioning repair, replacement, or maintenance rather than solar or battery work
- ✓ You require same-day or emergency HVAC service with responsive scheduling and quick diagnostic work
- ✓ Your project involves ductwork replacement, including specialized work like asbestos-wrapped duct removal that requires HVAC-specific expertise
- ✓ You prefer working with a high-involvement owner-operator known for honest recommendations and transparent pricing on heating and cooling systems
Questions to Ask Before Hiring
- → For Cinnamon Energy: What is your typical timeline from contract signing through final utility permission to operate, and how do you handle delays in permitting or inspection processes?
- → For Modern Air: Do you have experience installing heat pump systems sized for heating in addition to cooling, and what brands do you typically recommend for our climate?
- → For either company if considering heat pump work: Can you provide references from projects similar to mine, and what post-installation support do you offer if issues arise?
- → Ask both companies about warranty coverage on equipment versus installation labor, and what your maintenance requirements are to keep warranties valid.
The Bottom Line
Your decision is straightforward: choose based on your project type, not contractor comparison. If you're installing solar panels, adding battery backup, or upgrading electrical infrastructure for home electrification, Cinnamon Energy Systems has 13 years of specialized experience in exactly this work. If you need furnace or air conditioning repair, system replacement, ductwork work, or HVAC maintenance, Modern Air's 17 years of dedicated heating and cooling expertise is what you need. Both are established, properly insured contractors with strong customer feedback in their specialties. The only scenario requiring careful consideration is if you need heat pump installation without solar work, where Modern Air's pure HVAC focus may offer advantages, or heat pump installation as part of solar electrification, where Cinnamon Energy's integrated approach makes more sense.

Frequently Asked Questions
Yes, Modern Air installs heat pumps as part of their core HVAC business with 17 years of heating and cooling experience. The difference is context: Cinnamon Energy typically installs heat pumps as part of broader home electrification projects alongside solar panels, while Modern Air approaches heat pumps as HVAC replacements for traditional furnace and AC systems. If you're only replacing your heating and cooling system without solar work, Modern Air's dedicated HVAC focus may be more appropriate.
If your project centers on solar generation, battery storage, and the electrical infrastructure to support home electrification, Cinnamon Energy's 13 years of specialized experience makes them the clear choice. If you're focused on heating and cooling efficiency without solar components, Modern Air's veteran HVAC expertise is more relevant. For projects requiring both solar installation and traditional HVAC work, you may need to coordinate separate specialists.
Modern Air's 17 years versus Cinnamon Energy's 13 years both represent established, veteran-level experience. The more important factor is specialization rather than years. Modern Air's additional time has been spent deepening HVAC expertise, while Cinnamon Energy has focused those 13 years specifically on solar and battery systems. Both have sufficient experience to handle complex projects in their respective specialties.
Both companies receive strong feedback for communication, but in different contexts. Modern Air is noted for appointment confirmations via text and email, arrival notifications, and quick diagnostic explanations during service calls. Cinnamon Energy receives praise for thorough communication throughout longer solar projects, including detailed system design explanations and updates during permitting and utility coordination phases. Modern Air excels at responsive service communication, while Cinnamon Energy handles the extended communication needs of multi-week solar installations.

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.
