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.
Therma Tech
Those of you reading my reviews, you know how important quality of service is to me. Any company I come in contact with, I pay close attention to their quality of service, value and even some time aft...
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 Modern Air if...
- ✓ You're located in Morgan Hill, Scotts Valley, or the Santa Cruz Mountains where Modern Air has established service routes and familiarity with local building characteristics
- ✓ You value detailed appointment communication systems with text and email confirmations throughout the service process
- ✓ You've had previous positive experiences with the company or received a referral from someone in the southern Santa Clara County area
Consider Therma Tech if...
- ✓ You're located in San Jose or the northern Bay Area where Therma Tech has established operations and faster response times
- ✓ You appreciate visual documentation and want photos of diagnostic findings and completed work as part of the service record
- ✓ You need a company with documented experience handling both residential and commercial HVAC projects
Questions to Ask Before Hiring
- → What is your typical response time for service calls in my specific neighborhood?
- → Can you provide references from recent projects similar to mine (same equipment age, similar scope)?
- → What does your maintenance membership include and how does the pricing compare between annual service visits?
The Bottom Line
Choose based on location convenience rather than credential differences. Modern Air makes more sense if you're in Morgan Hill, Scotts Valley, or points south where they have established service routes. Therma Tech is the logical choice for San Jose and northern Bay Area locations. Both companies have veteran-level experience, identical insurance protections, and nearly indistinguishable customer satisfaction patterns. You're not compromising on quality, honesty, or capability with either choice. Call both for estimates if you're equidistant, and select based on availability and rapport with the technician who visits your home.

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.
