- ✓ Your project is purely HVAC-focused without electrical components, making specialist expertise more valuable than broad capabilities
Questions to Ask Before Hiring
- → Ask Got Watts how many HVAC installations they complete annually compared to electrical projects, and request references specifically for HVAC work similar to yours
- → Ask Hassler about their experience with heat pump installations if you're considering electrification, since this technology differs from traditional furnaces
- → For either company, ask how they handle unexpected complications during installation and whether quoted prices include contingencies for older homes
- → Ask about warranty terms on both equipment and installation labor, and who handles service calls if issues arise after installation
The Bottom Line
Choose Hassler Heating And Air Conditioning if your project is purely HVAC-focused, especially for complex diagnostics, older homes, or situations where 26 years of specialized heating and cooling expertise provides meaningful value. Their depth of experience matters significantly when installations reveal unexpected complications. Choose Got Watts if you're combining HVAC work with electrical upgrades, solar installation, or battery backup systems, or if you want a single contractor relationship for future home electrification projects. For straightforward HVAC replacements in newer homes, both companies are qualified, but Got Watts may offer better value if you have or anticipate electrical project needs.

Frequently Asked Questions
With 12 years licensed and clear customer feedback on successful HVAC installations, Got Watts demonstrates competence in heating and cooling work. However, their expertise spreads across multiple service areas while Hassler's 26 years focuses exclusively on HVAC systems. For straightforward replacements, Got Watts handles the work well; for complex diagnostics or older homes with potential complications, Hassler's deeper specialization provides more experience with problem-solving.
For truly straightforward replacements in newer homes with accessible installations, the experience gap matters less and Got Watts may offer better value. However, many projects that seem simple reveal complications once work begins—undersized ductwork, venting issues, or permit requirements. Hassler's 26 years means they've encountered these problems repeatedly and can address them efficiently rather than learning on your project.
This is actually Got Watts' strongest advantage—they can coordinate HVAC, solar, battery backup, and electrical panel upgrades as a single integrated project. If you're planning home electrification with multiple components, using one contractor who understands how these systems interact simplifies permitting, scheduling, and long-term service. Hassler would require you to coordinate separately with an electrical contractor for the solar work.
Both companies receive positive feedback for scheduling responsiveness. Hassler's reviews specifically mention quick service during heating emergencies, which makes sense given their exclusive HVAC focus and 26 years of established operations. Got Watts demonstrates responsiveness across their various service areas. For emergency HVAC service specifically, Hassler's specialization likely provides an edge in availability and parts inventory.

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.
