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 Future Air if...
- ✓ Your project involves commercial HVAC needs or requires a contractor with established commercial emergency response capabilities, where Future Air's experience is explicitly noted.
- ✓ You value working with a contractor who has seen nearly four decades of equipment evolution and can draw on extensive historical knowledge when diagnosing older systems or unusual problems.
- ✓ You're looking for a long-term service relationship rather than a one-time project, as Future Air's customer feedback emphasizes multi-decade partnerships and ongoing reliability.
- ✓ You prefer a company with maximum tenure in the local market, which can matter for understanding regional building codes, permit requirements, and inspector relationships accumulated over 37 years.
Consider Therma Tech if...
- ✓ You need rapid scheduling with same-day or next-day availability, which customers specifically mention receiving from Therma Tech even during high-demand periods like heat waves.
- ✓ You want detailed communication throughout the process, including photo documentation of work, thorough explanations of findings, and text/email appointment confirmations that reduce scheduling uncertainty.
- ✓ Your project is residential and falls within common HVAC work like furnace installation, AC replacement, heat pump upgrades, or ductwork services where Therma Tech has documented project experience.
- ✓ You're comparing multiple quotes and want transparent pricing without pressure tactics, as customers specifically note fair estimates and absence of upselling in Therma Tech's approach.
Questions to Ask Before Hiring
- → Ask Future Air about their residential project volume and communication processes, since customer feedback emphasizes relationships but doesn't detail the diagnostic communication and documentation that Therma Tech customers describe.
- → Ask Therma Tech about their experience with complex or older systems that might benefit from Future Air's additional 19 years of industry tenure, particularly if your home has unusual HVAC configurations.
- → Ask both companies for references from projects completed in the past 12 months that match your specific needs, since Future Air's 30-year customer relationships may not reflect current service delivery.
The Bottom Line
Both contractors are fully credentialed veterans with the experience to handle your HVAC needs safely and professionally. Choose Therma Tech if you're doing residential work and value responsive scheduling, detailed communication with photo documentation, and transparent pricing—their customer feedback demonstrates these strengths consistently. Choose Future Air if you need commercial HVAC capabilities, want maximum industry tenure for complex diagnostic situations, or are seeking a contractor for a long-term maintenance relationship where their 37-year track record and 30-year customer retention matter most. For standard residential installations and repairs, Therma Tech's documented communication practices and scheduling responsiveness give most homeowners clearer expectations about the service experience.

Frequently Asked Questions
For straightforward residential installations on newer homes, both companies have more than sufficient experience. The gap becomes meaningful if your home has an older system with potential hidden issues, unusual ductwork, or if you're combining HVAC work with other renovations where Future Air's decades of local building code navigation could help. For most standard replacements, Therma Tech's 18 years is fully adequate, and their detailed communication approach may provide more transparency during the process.
Future Air receives specific recognition for commercial emergency response times, while Therma Tech customers report same-day and next-day residential appointments even during heat waves. If you need a commercial emergency service relationship, Future Air has documented capability. For residential emergencies requiring rapid scheduling and diagnostic transparency, Therma Tech's customer feedback is more detailed. Ask each company directly about their emergency response protocols and typical wait times for your specific situation.
This likely reflects how each company has been reviewed and documented rather than actual capability differences. Therma Tech's customers provided specific project details in their feedback, while Future Air's reviews emphasized relationship quality and professional approach. Both veteran contractors handle comprehensive HVAC services. Ask Future Air directly about specific project types you need to confirm their residential service breadth matches their commercial capabilities.
Therma Tech customers specifically mention competitive pricing and fair estimates compared to other contractors, suggesting they're not premium-priced. Future Air's pricing isn't addressed in available feedback. Given Future Air's longer tenure and commercial focus, they may price differently for residential work. Get detailed written estimates from both contractors for your specific project to compare directly, and ask what's included in warranty coverage and post-installation support.

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.
