Pacific Rim Plumbing
Very professional and Very good service
Everything Good very good
Consider 3rdGen Heating & Cooling if...
- ✓ You need HVAC work—mini-split installation, heat pump service, furnace repair, or air conditioning—as this is 3rdGen's actual specialty and Pacific Rim doesn't offer these services
- ✓ Responsive scheduling matters to your timeline, as customers consistently report same-day and next-day availability from 3rdGen
- ✓ You value direct owner communication and want someone who will explain system options and answer questions thoroughly during the project
- ✓ You're installing modern heat pump or mini-split systems where 3rdGen has demonstrated specific installation expertise and cleanliness standards
Consider Pacific Rim Plumbing if...
- ✓ You need plumbing work—pipe repair, fixture installation, drain clearing, water heater service—as this is Pacific Rim's trade and 3rdGen doesn't handle plumbing
- ✓ Your project involves complex or unusual plumbing challenges where 45 years of diagnostic experience could prove valuable in identifying root causes
- ✓ You're comfortable proceeding without customer feedback verification and are willing to base your decision primarily on license tenure
- ✓ Your property is in or near Livermore where Pacific Rim has built their long-standing local presence and supplier relationships
Questions to Ask Before Hiring
- → For Pacific Rim: Ask for recent references from residential projects similar to yours, and confirm response times for scheduling initial consultations and starting work
- → For Pacific Rim: Ask how long their current crew has worked together and who will actually be on-site, given the absence of customer feedback about their current team
- → For 3rdGen: If your HVAC project has unusual complications or involves older systems, ask about their experience diagnosing hidden issues beyond standard installations
The Bottom Line
If you need HVAC work, hire 3rdGen—Pacific Rim doesn't offer those services. If you need plumbing work, Pacific Rim is your only option from this comparison, but their complete lack of customer feedback creates legitimate uncertainty about current service quality despite 45 years of licensing. Before hiring Pacific Rim, request and actually contact recent references to verify they deliver the reliability and professionalism their longevity suggests. For HVAC projects involving mini-splits, heat pumps, or standard residential systems, 3rdGen's proven responsiveness and installation quality make them a solid choice backed by actual customer confirmation.

Frequently Asked Questions
The license tenure proves they've stayed in business and maintained legal compliance for decades, which suggests operational stability. However, without customer feedback, you cannot verify current service quality, communication practices, or whether their crews are reliable and professional. For a major plumbing investment, ask Pacific Rim directly for recent references you can contact.
Four years is enough time to establish competency for standard HVAC installations and repairs, and their consistent customer feedback confirms reliable execution. For straightforward mini-split, heat pump, or furnace work, their proven track record matters more than additional decades of tenure. For highly complex or commercial projects, ask specifically about their experience with similar challenges.
No. These companies are licensed for different trades. 3rdGen handles heating, cooling, and ventilation systems. Pacific Rim handles water supply, drainage, and plumbing fixtures. You'll need to hire both if your project requires work in both areas.
3rdGen has documented feedback confirming punctuality, same-day scheduling, and direct owner communication. Pacific Rim's complete absence of review data means you cannot verify these service characteristics from past customer experiences. Ask Pacific Rim directly about their scheduling practices and who handles customer communication.

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.
