Customer Reviews

Excellent service from Stephan Reich. He was professional, knowledgeable, and diagnosed the issue within 15–20 minutes. The $200 consultation fee is on the higher side, but it was absolutely worth ...

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 Comfort Energy if...
- ✓ Your home has an older or complex HVAC system that may require troubleshooting uncommon issues, where three additional years of field experience could prove valuable in diagnosing hidden problems
- ✓ You need service beyond standard furnace and AC work, such as radiant heating systems or dryer vent cleaning, areas where Comfort Energy demonstrates project diversity
- ✓ You're located in Milpitas or the northern parts of Santa Clara County and prefer a contractor based nearby for faster response times
Consider Therma Tech if...
- ✓ Transparent pricing and a no-pressure approach to recommendations are priorities, particularly if you've had negative experiences with upselling from other contractors
- ✓ You value high owner involvement and direct accountability, which often means consistent service standards and easier resolution if issues arise
- ✓ You're in San Jose or the central Bay Area and want a contractor with a strong local presence in your immediate community
Questions to Ask Before Hiring
- → Ask both companies for references from projects similar to yours in age and complexity, particularly if your home has an older HVAC system or unusual configuration
- → Request a detailed written estimate that breaks down equipment, labor, and any additional work like ductwork modifications to compare pricing transparency
- → Ask how they handle warranty issues and what their callback rate is for post-installation adjustments, given both companies have strong but not perfect track records
The Bottom Line
Both Comfort Energy and Therma Tech are solid choices with veteran-level experience, full insurance protection, and strong customer satisfaction patterns. Choose Comfort Energy if you have a complex or older system where maximum field experience matters, or if you need specialized services like radiant heating. Choose Therma Tech if transparent pricing and direct owner accountability are priorities, particularly for straightforward installations where the three-year experience gap is less relevant. Either company will handle standard HVAC work competently—get estimates from both, compare the communication style and detailed breakdown you receive, and trust your instinct about which team you'd prefer in your home.

Frequently Asked Questions
For straightforward replacements in newer homes with standard ductwork, the three-year gap is unlikely to affect outcome quality—both have handled hundreds of similar projects. The experience difference becomes more relevant if your project involves troubleshooting intermittent issues, working with older ductwork that may need modification, or integrating with existing smart home systems where pattern recognition from additional field experience helps.
Both companies offer same-day or next-day service for emergencies and receive consistent praise for responsiveness, making this a genuine tie. Comfort Energy shows slightly broader equipment diversity in their project history, while Therma Tech's high owner involvement may provide more direct accountability during urgent situations. Ask each about their current availability and typical emergency response time when you call.
Therma Tech receives specific customer mentions about competitive pricing and no-pressure recommendations, which suggests a transparent pricing philosophy that customers notice and appreciate. Comfort Energy doesn't have negative pricing feedback, but it's not highlighted as a strength either. If you're price-sensitive or concerned about upselling, get written estimates from both and ask Therma Tech specifically about their pricing approach during the initial consultation.
High owner involvement typically means the owner is present for estimates, oversees installations, or directly handles customer communications, providing consistent quality control and a single point of accountability. This can make problem resolution faster and ensure company standards are maintained across all technicians. Ask Therma Tech whether the owner will be involved in your specific project and what that involvement looks like.

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.
