Frequently Asked Questions
No, these are separate trades. 3rdGen handles your furnace, heat pump, or HVAC heating system, while Valley Plumbing handles your water heater for domestic hot water. If you need work on both, you'll need to hire both companies or find contractors who hold both HVAC and plumbing licenses.
Not necessarily. Four years establishes a track record, and their focus on modern systems like heat pumps and mini-splits often requires current training that matters more than decades of experience with older technology. Their consistent customer feedback about installation quality and owner involvement suggests reliable workmanship despite being a younger company.
Longevity indicates stability and deep problem-solving experience, particularly valuable for unusual plumbing issues, older homes, or complex repairs where you need someone who has seen it before. However, customer feedback suggests their pricing is reasonable, and you should compare estimates. The value is in expertise, not necessarily premium pricing.
If it involves heating or cooling air in your home, contact 3rdGen. If it involves water supply, drainage, or hot water for sinks and showers, contact Valley Plumbing. A furnace not heating is HVAC; a water heater not producing hot water is plumbing. When in doubt, describe your specific symptom when calling and they'll tell you if it's their specialty.

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.
