Questions to Ask Before Hiring

- → Ask Ally Electric about their specific experience with your roof type and what protection measures they use during solar installations on tile or specialty roofing.
- → Request references from projects similar in scope to yours, particularly if you're doing a multi-system installation, to understand how each company handles project coordination.

Frequently Asked Questions
Yes, but it depends on your project scope. Ally Electric's 24 years means more experience with electrical code changes, panel upgrades, and troubleshooting integration issues that arise during solar installations. If your project is straightforward solar, that deeper electrical foundation is valuable. However, if you're coordinating solar with HVAC upgrades or energy efficiency improvements, Green Air's 18 years of HVAC expertise becomes equally important for ensuring all systems work together properly.
Both companies actively install battery storage systems and have documented Tesla Powerwall experience. Green Air emphasizes detailed customer education about how battery systems interact with HVAC equipment and energy usage patterns. Ally Electric's electrical background means stronger expertise in the wiring and panel requirements for battery integration. Ask both contractors about their specific battery installation volume and warranty service capabilities.
Yes, this favors Ally Electric significantly. With 24 years as an electrical contractor, they have extensive experience with panel upgrades, service increases, and electrical rewiring as core services, not secondary offerings. While Green Air can handle related electrical work for their solar installations, Ally's depth in electrical troubleshooting and code compliance provides stronger expertise when substantial electrical upgrades are part of the project.
High owner involvement typically means the business owner participates directly in project consultations, system design, or quality oversight rather than delegating everything to crews. This often results in more consistent communication and accountability. Ask each company specifically who will be your primary contact, whether the owner visits the job site, and how decisions get made if issues arise during installation.

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.
