Eagle Air
We discovered Eagle Air in 2018. We chose them over costco at the time because the owner Vince, unlike the the sales rep in a suit, got on his overalls and went under our house, got dirty, came out, a...
Deron was great at diagnosing our system and providing a solution to the problem. His knowledge and experience were great.
Technician was knowledgeable and did exactly what I asked. No up selling. Would call again.
Consider 3rdGen Heating & Cooling if...
- ✓ You're installing a Mitsubishi mini-split or modern heat pump system where 3rdGen's specialized recent training and repeated installations give them focused expertise in these specific technologies
- ✓ Direct access to the owner throughout your project is important to you, and you value the accountability and communication that comes with a hands-on, smaller operation
- ✓ You're located in Berkeley or nearby areas where 3rdGen's local presence means faster response times for service calls and follow-up visits
- ✓ Your project is relatively straightforward and you're drawn to a growing company that's building its reputation on meticulous work and customer service
Consider Eagle Air if...
- ✓ Your HVAC system is older, unusual, or showing symptoms that require deep diagnostic experience from someone who's genuinely seen it all over three decades
- ✓ You value the stability and institutional knowledge of a veteran company that's successfully operated through multiple economic cycles and industry changes
- ✓ You want an established maintenance program with systematic appointment reminders and long-term service relationships rather than managing schedules yourself
- ✓ You're in Livermore or eastern Alameda County where Eagle Air's location provides better local coverage and faster emergency response
Questions to Ask Before Hiring
- → Ask 3rdGen for references from projects involving systems similar to yours, particularly if your project involves complexity beyond standard installations
- → Ask Eagle Air which specific technician would handle your project and how long they've been with the company, since experience varies within larger teams
- → Ask both companies how they handle unexpected complications discovered during installation, and whether their estimates include contingency pricing for common hidden issues
The Bottom Line
Eagle Air's 33 years of experience represents substantial accumulated knowledge that matters when projects get complicated, making them the safer choice for complex diagnostics, older homes with quirks, or situations where you want the confidence of a company that's genuinely seen everything. However, 3rdGen offers compelling advantages if you're in Berkeley, want direct owner involvement throughout your project, or are specifically installing Mitsubishi mini-split or heat pump systems where their focused expertise is current. For straightforward installations in Berkeley with modern equipment, 3rdGen's specialized attention and hands-on approach may serve you better. For diagnostic challenges, unusual systems, or eastern Alameda County locations, Eagle Air's veteran experience is the stronger bet.

Frequently Asked Questions
For routine maintenance and simple repairs, the experience gap matters less since both companies handle these jobs regularly and receive positive feedback on basic service work. The experience difference becomes significant when diagnostics get complicated, when installations reveal unexpected structural or ductwork issues, or when older systems show unusual failure patterns. If your project is truly straightforward, 3rdGen's four years is adequate experience, but if there's any complexity or your home has quirks, Eagle Air's deeper experience reservoir provides more problem-solving capability.
3rdGen has developed specific expertise in heat pump installations, particularly Mitsubishi systems, and their recent training means they're current on the latest heat pump technology and rebate programs. Eagle Air also handles heat pump installations with the advantage of three decades of experience adapting to home-specific challenges. If you're installing a Mitsubishi mini-split system, 3rdGen's focused specialization is advantageous. For other heat pump brands or more complex whole-home retrofits where unexpected issues are likely, Eagle Air's broader experience may prove valuable.
Four years of licensure means 3rdGen has completed hundreds of installations and has moved beyond startup phase into established operation. The consistent positive feedback about installation quality, particularly the owner's direct involvement and meticulous worksite practices, demonstrates competence. However, you're trusting a company with a shorter track record for warranty support and long-term accountability. Ask for references from similar replacement projects and confirm the owner will personally oversee your installation if that hands-on involvement is important to you.
Location significantly impacts response times for emergency calls and the likelihood of same-day service. If you're in Berkeley or western Alameda County, 3rdGen's local presence means they can reach you faster, which matters during heating failures on cold nights or AC breakdowns in summer. If you're in Livermore or eastern areas, Eagle Air is your local option with better proximity. Both companies receive praise for scheduling flexibility, but geographic convenience affects both emergency response and the ease of warranty or follow-up visits.

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.
