Frequently Asked Questions
Zero Energy Associates installs solar systems and can likely handle associated electrical work within their scope, but major panel upgrades may require coordination with an electrical contractor. Ask Zero Energy Associates specifically whether your panel upgrade needs fall within their electrical capabilities or if they subcontract that portion. Eleos Electric could handle the panel upgrade but would not install the solar system itself.
The experience gap is less relevant than the trade specialization. Zero Energy Associates' 23 years means deeper expertise in HVAC and solar-specific challenges like system integration and energy efficiency optimization. Eleos Electric's 10 years provides solid electrical contracting experience including complex fire rebuilds. Choose based on which trade your project requires, not experience years alone.
Eleos Electric is the appropriate choice for EV charger installations—this is electrical work requiring circuit installation, potentially panel upgrades, and permit coordination. Zero Energy Associates focuses on HVAC and solar systems, not standalone electrical installations.
Zero Energy Associates specializes in gas-to-electric conversions and heat pump installations, with customers specifically mentioning this work in their reviews. This project requires HVAC expertise for proper system sizing, load calculations, and integration with your home's heating needs—all within Zero Energy Associates' core competency.

How We Compare Contractors

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.
