Questions to Ask Before Hiring
- → If planning both solar and heat pump installation: Ask each contractor how they calculate electrical loads and whether they coordinate with the other trade to ensure proper system sizing
- → For Element Power Systems: Ask about their post-installation monitoring support and how they handle equipment issues that emerge years after installation, given customer concerns in this area
- → For Hassler: Ask whether they have experience sizing HVAC systems for homes with existing or planned solar installations to optimize energy usage
The Bottom Line
This comparison only makes practical sense if you're planning both solar installation and HVAC work as part of a comprehensive home electrification project. In that scenario, contact Hassler first to evaluate and size your heating and cooling needs, then work with Element Power Systems to design solar capacity that supports those loads. If you only need one service, the choice is straightforward: Element Power Systems for solar photovoltaic installation, Hassler for any heating, cooling, or ventilation work. Both companies maintain proper licensing, workers compensation, and equivalent bonds, giving you solid contractor protections regardless of which trade you need.

Frequently Asked Questions
No, these are separate trades requiring different licenses and expertise. Element Power Systems holds solar contractor licensing, while Hassler holds HVAC licensing. If you're planning both projects, you'll need to hire each company for their respective specialty and ensure they coordinate on electrical capacity and load calculations.
If you're switching to an electric heat pump, install it first so your solar system can be sized to account for the increased electrical load. If you're replacing a gas furnace with another gas system, the order matters less. Both contractors can advise on timing, but coordination between them is essential for proper system sizing.
Not for comparison purposes, since they work in different trades. Hassler's 26 years reflects deep HVAC expertise, while Element Power Systems' 16 years represents substantial solar experience. Both are veteran contractors with extensive track records in their respective fields.
Start with Hassler to assess your heating and cooling needs and determine heat pump feasibility and sizing. Then contact Element Power Systems to design a solar system that accounts for your HVAC electrical loads. This sequence ensures your solar installation is properly sized for your actual energy consumption including the new HVAC equipment.

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.
