Frequently Asked Questions
Got Watts has 12 years of licensed experience and handles heat pump installations, furnaces, and ductwork as documented in customer feedback. However, their expertise originated in electrical work and solar installation. For standard HVAC replacements they're qualified, but if your system has unusual complications or you're troubleshooting persistent problems, Hassler's 26 years of HVAC-only focus provides deeper diagnostic experience.
Hassler is licensed for HVAC work, not electrical contracting. Many heat pump installations require electrical panel upgrades or circuit additions. Ask Hassler directly whether they coordinate electrical work through partners or if you'll need to hire a separate electrician.

For straightforward furnace replacement, Hassler's 26 years of exclusive HVAC focus is the stronger choice.

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.
