Customer Reviews
Modern Air
We replaced all of our asbestos-wrapped ductwork and installed a new heat pump system in late October. The entire Modern Air team did a great job with this relatively large project. Andrew, the owner...
Outstanding! Professional! Efficient! Great communications! Same day service. Texts and emails confirming all communications. Installation several days later. A special thanks to Billy, Alfredo and hi...
Alfredo was professional and courteous, and so was the previous person who came out for quote. Modern Air does a great job with their client communications, and their cost is reasonable.
Thermal Mechanical
Good company!
Consider Modern Air if...
- ✓ Your HVAC project involves residential heating or cooling work where communication and transparency matter—customers consistently mention clear explanations and honest recommendations without pressure tactics.
- ✓ You value responsive scheduling and need confidence in same-day availability, as Modern Air has documented patterns of prompt service and proactive appointment notifications.
- ✓ Your project involves specialty work like ductwork replacement or asbestos-wrapped duct removal where you want a contractor with documented residential experience in these specific areas.
- ✓ You prefer working with a company where customer feedback confirms current service quality rather than relying solely on licensing longevity.
Consider Thermal Mechanical if...
- ✓ Your project involves unusually complex mechanical systems or legacy equipment where 57 years of industry experience could provide exposure to problems newer contractors haven't encountered.
- ✓ You're willing to conduct thorough due diligence by requesting recent customer references directly, visiting completed job sites, and verifying the company's current residential service focus before committing.
- ✓ Your project timeline is flexible enough to allow additional vetting time, as the lack of public customer feedback requires more upfront investigation to understand current service practices and crew capabilities.
Questions to Ask Before Hiring
- → Ask Thermal Mechanical directly for at least three recent residential HVAC customer references you can contact, and inquire about their current project mix between commercial and residential work.
- → Ask Thermal Mechanical about their typical response time for service calls, their communication practices for scheduling and updates, and how long their current service technicians have been with the company.
- → Ask both companies for a detailed written estimate that includes specific equipment models, labor breakdown, warranty terms, and project timeline to compare their approaches to transparency.
The Bottom Line
For most homeowners needing HVAC service this week, Modern Air represents the lower-risk choice. Their 17 years qualifies as veteran-level experience for handling both routine and complex residential heating and cooling projects, and consistent customer feedback confirms responsive scheduling, clear communication, and honest pricing. Thermal Mechanical's 57-year history is impressive on paper, but without customer reviews to verify current service quality, crew capabilities, or residential focus, you're making a decision with significant information gaps. If you're considering Thermal Mechanical, invest time in thorough due diligence—speak with recent customers, verify their residential workload, and confirm response times before committing. Otherwise, Modern Air offers documented reliability for residential HVAC work.

Frequently Asked Questions
Licensing longevity proves the business has survived, not that current service quality meets your needs. Modern Air's 17 years still qualifies as veteran-level experience for diagnosing complex HVAC issues, and their documented customer feedback confirms what you'll actually experience. Without recent reviews, Thermal Mechanical's decades of licensing remain an unknown variable for current service delivery.
This could indicate several scenarios: the company may focus primarily on commercial contracts rather than residential work, they may serve a limited repeat customer base, or they simply haven't cultivated an online review presence. You should ask them directly about their current residential HVAC workload and request verifiable recent customer references before hiring.
With 17 years of licensed experience, Modern Air has worked through multiple generations of HVAC equipment and technology changes. Customer feedback specifically mentions successful diagnosis of technical problems and handling specialty work like asbestos-wrapped ductwork removal, indicating capability beyond basic repairs. Their veteran-tier classification reflects substantial industry depth.
Years licensed matters, but only when combined with verifiable current service quality. A 57-year-old business with unknown current practices poses more risk than a 17-year veteran with documented transparency and customer satisfaction. For residential HVAC work this week, predictable service quality based on recent feedback provides more decision confidence than licensing longevity alone.

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.
