Frequently Asked Questions
No, these contractors have separate specializations. Sun Light & Power works exclusively on solar systems and would not handle HVAC work. Contra Costa Heating focuses on heating and cooling systems and does not install solar panels. You would need to hire each company separately for their respective specialties, though coordinating both projects could help with electrical planning if you're installing both systems.
For solar work, yes—Sun Light & Power's 49 years means they've seen multiple generations of solar technology, can repair systems from defunct manufacturers, and are far more likely to still be operating when your system needs service in 20 years. For HVAC work, Contra Costa's 14 years provides sufficient technical experience for standard installations, though their post-installation support issues are a more relevant concern than their years in business.
The pattern of customers reporting difficulty reaching them for post-installation service is a legitimate concern, especially since HVAC systems require periodic maintenance and occasional warranty work. Before hiring, get explicit written terms about warranty response times, request direct contact information for service scheduling, and ask for references from customers who needed follow-up support. If you proceed, be prepared to be persistent about follow-up needs.
Absolutely. Solar systems operate for 25-30 years and will eventually need inverter replacements, troubleshooting, or component repairs. Sun Light & Power's ability to repair systems they didn't originally install and their 49-year operational history strongly suggest they'll be available when you need service years from now, unlike many solar companies that have already exited the market.

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.
