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.
Very honest and knowledgable. They arrive right on time and are able to root-cause the issue and fix it in no time. Highly recommend them.
Consider Golden Air if...
- ✓ You need a straightforward repair diagnosed and fixed quickly, where same-day service from an owner-operator matters more than decades of experience
- ✓ Your project involves basic furnace repair, airflow diagnostics, or air conditioning service rather than complete system replacement
- ✓ You prefer working directly with the business owner throughout the entire service call rather than a crew
- ✓ Budget is tight and you want detailed explanations of repair options at different price points
Consider Therma Tech if...
- ✓ You're replacing a furnace, installing a heat pump, or undertaking any major HVAC installation where 18 years of experience prevents costly sizing or ductwork mistakes
- ✓ Your home has older systems or ductwork where hidden complications require a contractor who has seen similar scenarios hundreds of times
- ✓ You need comprehensive capabilities like ductwork replacement, dual fuel systems, or commercial-grade equipment that a newer contractor may not have installed before
- ✓ You value long-term relationships and want a contractor with proven staying power, as evidenced by customers returning over multiple years
Questions to Ask Before Hiring
- → Ask Golden Air for references on projects matching your specific needs, particularly if considering them for installation work beyond their typical repair focus
- → Ask Therma Tech about crew tenure and who specifically would handle your project, since their size may mean less direct owner involvement than Golden Air provides
- → If your project involves major installation, ask both contractors how many similar systems they've installed in the past two years and request photos of comparable completed projects
The Bottom Line
For major installations, system replacements, or projects involving ductwork modifications, Therma Tech's 18 years of licensed experience provides substantially more protection against costly mistakes and complications. Their proven installation crews and comprehensive project history justify choosing them for anything beyond straightforward repairs. Golden Air makes sense for diagnostic repairs and urgent service calls where you want fast, direct owner involvement and budget-conscious repair options. Both are properly licensed and insured, but if you're investing thousands in a new furnace or heat pump, Therma Tech's veteran status isn't just a nice-to-have—it's meaningful insurance against problems a newer contractor hasn't encountered yet. Get quotes from both, but lean toward Therma Tech unless your project is a simple repair where Golden Air's responsive, owner-driven service offers clear advantages.

Frequently Asked Questions
Not necessarily, but it means less margin for error. Four years is enough for standard installations, but Therma Tech's 18 years means they've encountered and solved complications Golden Air simply hasn't seen yet—unusual ductwork configurations, older home challenges, or equipment compatibility issues. For straightforward replacements in newer homes, the gap matters less. For older homes or complex systems, experience depth provides real protection.
Response time appears similar, but same-day service from Golden Air typically means the owner diagnosing your problem personally, while Therma Tech dispatches from a larger crew. Both work well for urgent repairs. The practical difference emerges in project complexity—Golden Air excels at quick diagnosis and single-visit fixes, while Therma Tech handles both emergency repairs and complex installations requiring multiple crew members.
Customer feedback describes both as offering fair pricing, with Golden Air specifically noted for presenting budget-friendly options and Therma Tech praised for competitive estimates. Veteran contractors sometimes charge more for expertise, but sometimes leverage supplier relationships and efficiency for better pricing. Get quotes from both—the difference may be smaller than expected, and paying slightly more for 18 years of experience often prevents expensive do-overs.
Therma Tech shows stronger evidence of long-term customer relationships, with reviews mentioning annual maintenance over multiple years and customers returning for separate projects. Their comprehensive inspection approach and 18-year track record suggest better odds they'll still be servicing your system in five years. Golden Air can certainly handle maintenance competently, but their four-year history provides less certainty about long-term business stability.

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.
