Questions to Ask Before Hiring
- → Ask Air Sharks for references from projects similar in complexity to yours, particularly if your home was built before 2000 or involves unusual ductwork configurations.
- → Ask Therma Tech about their current scheduling availability, as their 18-year reputation may result in longer wait times for non-emergency work.
- → Confirm with both companies how they handle unexpected complications discovered during installation and whether their quotes include contingency for common issues in older homes.
The Bottom Line
Therma Tech's 18 years of licensing experience provides meaningful advantages for complex projects, older homes, emergency situations, and any scenario where unexpected complications might arise. Air Sharks offers comparable service quality and communication for straightforward installations at competitive pricing, making them a solid choice when project scope is clear and complications are unlikely. If your home was built before 2000, involves legacy equipment, or requires emergency service reliability, Therma Tech's depth of experience justifies choosing them. For modern equipment installations in newer homes where you value responsive communication and competitive pricing, Air Sharks delivers professional service with proper insurance and bonding. Request quotes from both, but give weight to Therma Tech's track record if your project has any complexity beyond a standard replacement.

Frequently Asked Questions
For a straightforward replacement in a newer home with standard ductwork, the experience difference matters less—both companies handle these installations routinely. The gap becomes more significant if your home has older ductwork, nonstandard configurations, or if complications arise during the project. Therma Tech's 18 years means they've likely encountered and solved problems Air Sharks hasn't yet faced.
Both companies offer responsive scheduling with next-day availability in many cases. Therma Tech's reviews specifically mention same-day emergency service during heat waves and critical equipment failures. Air Sharks emphasizes same-day and next-day appointments but doesn't have the same pattern of emergency callouts in their review themes. If emergency response speed is critical, ask both companies directly about their current emergency availability.
Therma Tech's high owner involvement typically means more consistency in decision-making, direct access to leadership when issues arise, and continuity across multiple service calls over years. Air Sharks' moderate owner involvement suggests a more delegated team structure, which can work well for routine projects but may require escalation for complex decisions. Both approaches can deliver quality work; the difference is in communication channels and decision authority.
Both companies receive customer feedback describing their pricing as competitive and fair compared to other contractors. Air Sharks specifically gets mentions of competitive pricing in reviews, while Therma Tech is described as having fair estimates. The experience premium, if any, appears minimal based on customer feedback. Request detailed quotes from both to compare directly for your specific project.

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.
