Frequently Asked Questions
This appears to be a directory categorization issue or broad search term match. American Chiller Service does not perform residential solar installations despite both companies being located in Rancho Cordova. If you're searching for solar contractors, Aztec Solar is the appropriate choice. American Chiller Service would only be relevant if you have commercial refrigeration equipment needs.
Their expertise is in commercial refrigeration systems, not residential solar electrical work. Solar installations require specific knowledge of photovoltaic system design, utility interconnection requirements, battery inverter integration, and residential code compliance that differs entirely from commercial chiller electrical systems. You need a contractor with documented residential solar experience.
Yes, and their customer feedback confirms they handle both. Pool solar heating uses different technology than photovoltaic panels, but Aztec Solar's project list and reviews show they perform both types of installations along with battery backup and ground mount systems. Their 37 years span the evolution of residential solar technology.
You would hire both companies for their respective specialties. Aztec Solar would handle your residential solar installation, while American Chiller Service would address any commercial chiller or refrigeration equipment if you operate a business facility. These are separate projects requiring different contractor expertise.

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.
