Questions to Ask Before Hiring
- → Confirm you have the correct contractor for your specific project type—solar installation versus HVAC service are unrelated trades
- → If you need both solar and HVAC work, ask each contractor whether your planned projects should be sequenced in a particular order
- → Ask whether either contractor coordinates with the other trade if your project involves both energy system upgrades and HVAC modifications
The Bottom Line
This comparison only makes sense if you need both solar installation and HVAC service for separate projects. Cobalt Power Systems is the contractor to call for solar panel installation, battery backup systems, or photovoltaic upgrades. Supreme Air Systems is who you contact for furnace maintenance, air conditioner repairs, or HVAC system installations. Both are experienced, properly licensed, and carry appropriate insurance and bonds for their respective trades. If you're only planning one project, select the contractor whose specialty matches your actual need. If you received both names for a single project type, one referral is incorrect—clarify what work you actually need done.

Frequently Asked Questions
You likely received these names for two separate projects or there's been a miscommunication about the type of work you need. Solar installation and HVAC service are completely different trades requiring different licenses and expertise. If you genuinely need both services, you'll be hiring both companies for different scopes of work.
Solar panels generate electricity but don't directly interact with your heating and cooling equipment unless you're specifically electrifying your heating system as part of an energy upgrade. If you're replacing a roof, that timing might affect both solar installation and HVAC equipment placement, but the actual work remains separate. Ask each contractor about coordination if you're doing major work in both categories.
Supreme Air Systems has 28 years licensed versus Cobalt's 23 years, but this comparison is meaningless since they operate in different industries. Cobalt's 23 years in solar is substantial given that residential solar has only been widely available for about 25 years. Supreme's 28 years in HVAC represents deep experience across multiple generations of heating and cooling technology.
No. Cobalt Power Systems holds solar contractor licensing for photovoltaic installations, while Supreme Air Systems holds HVAC contractor licensing for heating and cooling systems. Each trade requires specialized training, equipment, and licensing. Neither company is qualified or legally permitted to perform the other's work.

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.
