Key Differences
What Customers Say
Aircom Mechanical
Insufficient residential customer feedback to establish pattern, with only thermostat replacement documented as residential project type.
Therma Tech
Customers consistently praise rapid scheduling responsiveness, thorough diagnostic explanations with photo documentation, professional installation quality, and fair pricing without pressure tactics.
Key Takeaway: Therma Tech provides extensive validation of residential service quality across diverse project types while Aircom's limited review history leaves residential service capability unclear despite longer licensing history.
Customer Reviews
Aircom Mechanical
If you have a commercial building you should get professional service from Aircom Mechanical.
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 Aircom Mechanical if...
- ✓ You have a commercial property needing mechanical services where Aircom's focus and four-decade experience align with the project scope
- ✓ Your project is straightforward and you're comfortable working with a contractor whose residential service approach is less documented
- ✓ You prefer working with the most senior contractor available regardless of other service factors
Consider Therma Tech if...
- ✓ You're a homeowner needing residential HVAC service with confidence in responsive scheduling and clear communication throughout the project
- ✓ Your system requires diagnostic work or you want thorough explanations with photo documentation of findings and recommendations
- ✓ You value documented customer experience showing professional installations, clean worksites, and fair pricing practices
- ✓ You need emergency or same-day service capability with a proven track record of accommodating urgent requests
Questions to Ask Before Hiring
- → Ask Aircom specifically about their residential service approach, typical response times for homeowner projects, and whether they can provide recent residential references
- → Ask Aircom whether the same crew handles both commercial and residential work, and how scheduling prioritization works between project types
- → Ask Therma Tech for references from projects similar to yours in scope and equipment type to confirm their experience matches your specific needs
The Bottom Line
While Aircom's 39 years of licensing deserves respect, Therma Tech presents the clearer choice for most residential HVAC projects. Therma Tech demonstrates documented capability across the full range of homeowner needs—installations, replacements, repairs, and maintenance—with customer feedback validating responsive scheduling, thorough communication, and professional execution. Aircom's commercial focus and limited residential validation create uncertainty about service responsiveness and residential crew experience. Unless your project is commercial or you have specific reasons to prioritize maximum licensing tenure, Therma Tech offers more predictable residential service quality with proven customer satisfaction patterns.

Frequently Asked Questions
Both qualify as veteran contractors with deep technical knowledge. The practical difference lies in documented residential service capability rather than years alone. Aircom's additional 21 years of licensing doesn't translate to clear advantage if their focus is commercial work, while Therma Tech shows extensive residential project validation across the specific services most homeowners need.
Limited residential review history combined with apparent commercial focus suggests Aircom may serve primarily business clients rather than homeowners. This creates uncertainty about their residential service model and responsiveness for typical homeowner projects. Before hiring, ask Aircom directly about the percentage of residential versus commercial work they handle.
Aircom's 39-year mechanical licensing suggests technical capability, but available data only shows thermostat replacement as a documented residential project type. Therma Tech demonstrates validated experience across furnace installations, AC replacements, heat pumps, ductwork, and emergency repairs. Ask Aircom specifically about their experience with your particular project type and request recent residential references.
Therma Tech shows documented same-day and emergency service capability with customer feedback specifically mentioning heat wave emergency calls and rapid response times. Aircom uses an after-hours answering service but their emergency response capability for residential customers is unclear. If emergency availability is important, confirm Aircom's after-hours service model and typical response times before making your decision.

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.
