Consider All Bay Solar Construction if...
- ✓ You're planning a solar panel installation, either on an existing roof or coordinated with a roof replacement that's needed anyway
- ✓ Your project involves electrical panel upgrades or battery storage systems to support solar energy
- ✓ You want a single contractor managing both the roofing and solar aspects to avoid coordination problems between separate trades
- ✓ Your roof is approaching end-of-life and you're considering solar, making an integrated project more cost-effective than doing them separately
Consider Kevel Home Performance if...
- ✓ You need HVAC system replacement, ductwork installation, or furnace upgrades in your San Francisco home
- ✓ Your older or historic home has air sealing, insulation, or energy efficiency issues unrelated to solar power
- ✓ You want to access Energy Upgrade California Program incentives for heating and cooling improvements
- ✓ You're considering window inserts or other thermal performance upgrades to reduce heating and cooling costs without full window replacement
Questions to Ask Before Hiring
- → If considering solar, ask All Bay about their experience with your specific roof type and how they handle warranty coordination between roofing and solar components
- → If considering HVAC work, ask Kevel about their experience with your home's age and configuration, and whether an energy audit would identify additional savings opportunities
- → For either company, ask for references from projects completed in the past year that match your project scope and home type

If you need heating and cooling system work, ductwork, or energy efficiency improvements for an older home, Kevel Home Performance is the relevant choice. Both are properly licensed and insured San Francisco contractors with solid credentials in their respective fields.

Frequently Asked Questions
No, these companies operate in separate specialties. All Bay Solar Construction handles solar and roofing but not HVAC systems. Kevel Home Performance handles heating, cooling, and energy efficiency but not solar installations. You would need to hire both companies for those respective projects, though Kevel's energy assessments might inform whether solar makes sense as part of a broader efficiency strategy.
The experience gap is relevant within each specialty but not across them. All Bay's 15 years means deeper experience with solar technology evolution, permit processes, and roofing-solar integration. Kevel's 9 years still represents solid experience in HVAC and energy efficiency work. Both have sufficient tenure to handle complex projects in their respective fields.
This depends entirely on what's driving your energy costs. If you're paying high electric bills and have good sun exposure, All Bay's solar installations directly reduce electricity costs through generation. If your heating and cooling systems are inefficient or your home loses conditioned air through leaks and poor insulation, Kevel's efficiency upgrades address those losses. An energy audit from Kevel could help identify whether HVAC improvements or solar would deliver greater savings for your specific situation.
Kevel Home Performance explicitly participates in the Energy Upgrade California Program and helps homeowners access those incentives for HVAC and efficiency work. All Bay Solar Construction may be able to coordinate with solar incentive programs, but that's a separate set of rebates and tax credits. Ask All Bay directly about current federal solar tax credits and any state or utility solar incentives available for your project.

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.
