Questions to Ask Before Hiring
- → Ask Melgar Mechanical for at least three recent references from projects similar to yours and follow up on the mixed service feedback concerns
- → Ask both companies how long their current service technicians have been with the company to gauge crew stability
- → Ask Supreme Air Systems about their maintenance program pricing and whether semi-annual visits make sense for your system's age and usage patterns
The Bottom Line
Supreme Air Systems is the more reliable choice for most homeowners. Their 28 years of operation, documented long-term customer relationships, and proven maintenance service model provide substantially lower risk than Melgar Mechanical's five-year track record with mixed feedback. The experience difference matters most when diagnosing failing systems, handling installation complications, or establishing ongoing maintenance relationships. Choose Melgar Mechanical only if they're significantly cheaper and your project is straightforward enough that limited experience poses minimal risk. For everyone else, Supreme Air Systems' verifiable reliability and depth of experience justify any reasonable price premium.

Frequently Asked Questions
It matters less for simple replacements in ideal conditions, but HVAC projects rarely go exactly as planned. Older homes often reveal ductwork issues, electrical complications, or structural challenges during installation. Supreme Air Systems has encountered these problems hundreds of times over 28 years, while Melgar Mechanical has had five years to build that problem-solving knowledge. The experience gap becomes critical when unexpected issues arise mid-project.
Their business model centers on long-term customer relationships rather than one-time installations. The semi-annual maintenance visits generate recurring revenue while extending system life and preventing emergency failures. Many customers stay with them for decades specifically because of this proactive service approach. If you prefer transactional service without ongoing commitments, this model may not align with your preferences.
The data indicates inconsistent customer experiences without sufficient review volume to identify specific patterns. This could reflect growing pains as they build their service operations, variability in technician quality, or communication issues. Without more feedback data, you're accepting higher uncertainty about service quality. Ask them directly about the mixed feedback and request multiple recent references.
That depends on your project complexity and risk tolerance. For complex diagnostics, commercial work, or older systems with potential hidden issues, Supreme Air Systems' experience justifies higher costs through faster problem resolution and lower likelihood of callbacks. For straightforward projects where you're comfortable accepting more risk, Melgar Mechanical may offer adequate service at lower cost.

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.
