We discovered Eagle Air in 2018. We chose them over costco at the time because the owner Vince, unlike the the sales rep in a suit, got on his overalls and went under our house, got dirty, came out, a...

Consider Sunvault if...
- ✓ You're pursuing solar installation to reduce electricity costs and Sunvault's competitive pricing fits your budget, but plan to have their installation work inspected by an independent roofer to verify proper flashing and weatherproofing.
- ✓ You're working against a net metering deadline and need a solar contractor who has experience completing projects under time pressure from policy changes.
- ✓ You're comfortable with a higher-touch relationship where you may need to monitor workmanship quality and request follow-up evaluations if issues arise.
Consider Eagle Air if...
- ✓ You need HVAC repair, replacement, or maintenance and want a contractor with three decades of diagnostic experience who can accurately assess whether your system needs replacement or just targeted repairs.
- ✓ You value honest recommendations over sales pressure—Eagle Air's consistent feedback about avoiding unnecessary upselling on older systems indicates they'll tell you when a repair makes more sense than replacement.
- ✓ You need responsive service with same-day or next-day availability for emergency heating or cooling failures, backed by technicians who explain issues clearly and respect your home.
- ✓ You want ongoing maintenance through a proactive service program that contacts you for bi-annual tune-ups rather than requiring you to remember scheduling.
Questions to Ask Before Hiring
- → For Sunvault: Ask for references specifically related to roof integrity after installation, and request documentation of their waterproofing warranty and process for addressing any leaks that develop.
- → For Sunvault: Given mixed workmanship feedback, ask who will inspect the completed installation and whether they use third-party quality verification.
- → For Eagle Air: If considering a full HVAC replacement, ask for a detailed cost comparison between repairing your current system versus installing new equipment, including expected lifespan of each option.
The Bottom Line
This comparison only matters if you're choosing between solar installation and HVAC replacement for budget allocation. If you need HVAC work, Eagle Air is the clear choice—33 years of experience, consistent customer praise for honest service and technical expertise, and proven responsive scheduling make them a reliable contractor. If you're pursuing solar installation, Sunvault offers competitive pricing but comes with meaningful concerns about workmanship consistency. The mixed quality feedback is particularly problematic for roof-penetrating work. If you proceed with Sunvault, protect yourself by hiring an independent inspector to verify proper flashing and weatherproofing after installation, and document everything in writing.

Frequently Asked Questions
Yes, significantly. Eagle Air's 33 years means they've handled equipment failures and installation complications across multiple technology generations, which translates to better troubleshooting when problems arise. Sunvault's 6 years is respectable for solar but doesn't provide the same depth for handling unexpected roof conditions or electrical integration issues. For roof-penetrating work like solar, experience with weatherproofing variations matters considerably.
Yes. Solar installations involve permanent roof penetrations and structural mounting that must withstand decades of weather exposure. Workmanship issues requiring follow-up evaluation suggest inconsistent quality control. Unlike HVAC equipment that can be serviced or replaced, poor solar installation can cause roof leaks and structural damage that's expensive to remediate. Ask Sunvault specifically how they quality-check installations and handle warranty claims.
No. Eagle Air holds an HVAC contractor license, not a solar contractor license. They can only legally perform heating and cooling work. If you want both services, you'll need separate contractors, which means coordinating two projects and two timelines.
Prioritize based on immediate need and return timeline. If your HVAC system is failing or inefficient, replace it first—you need heating and cooling now. Solar provides long-term electricity savings but typically takes 7-12 years to break even. Consider that a new, efficient HVAC system will reduce your electricity needs, which affects your solar sizing and savings calculations. You might replace HVAC first, then right-size your solar installation based on your new consumption patterns.

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.
