Everyone at Therma Tech was great to work with and professional. They worked with us to get the duct work done as soon as possible to get the heat back on for our tenants.

The Bottom Line
Therma Tech is the clearer choice for most homeowners making this decision this week.

Melgar Mechanical meets basic licensing requirements but offers limited transparency about service quality through its sparse review history with mixed feedback. Unless you have personal experience with Melgar Mechanical or a trusted referral, Therma Tech's documented track record makes it the lower-risk choice for your HVAC project.

Frequently Asked Questions
It matters less for simple swaps with no complications, but installations frequently reveal unexpected issues like inadequate ductwork, outdated electrical, or code compliance problems. An 18-year veteran has seen these scenarios hundreds of times and knows how to handle them without delays or cost surprises. For diagnostic repairs where the problem isn't obvious, the experience gap becomes critical.
Limited reviews combined with mixed feedback notes mean you're making a decision without sufficient data about service consistency, communication quality, or how they handle problems. Therma Tech's extensive feedback shows patterns you can count on—same-day service, clean work, fair pricing. With Melgar Mechanical, you're essentially taking a chance that your experience will be positive.
Not necessarily. Customer feedback specifically mentions competitive and fair pricing compared to other contractors. Established companies often have better supplier relationships and operational efficiency that can offset their experience premium. The real question is whether saving a few hundred dollars is worth the uncertainty when both companies have the same bond protection.
Therma Tech has documented same-day and emergency service during heat waves in customer feedback, showing both the capacity and responsiveness to handle urgent calls. Melgar Mechanical's emergency capabilities are unclear from available information, which is something you should ask them directly before an emergency occurs.

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.
