Customer Reviews
Poco Solar Energy
Eddie showed up on time and got right to it and figured out the problem in short order. He completed the repairs in no time.
I've been a customer of Poco for over 16 years. I thought Darwin was irreplaceable, but I was wrong. Ed Is about the only person who could've replaced Darwin with his friendliness and expertise. Appre...

Consider Poco Solar Energy if...
- ✓ You need a contractor with proven solar expertise who can diagnose complex issues like panel leaks, system malfunctions, or integration problems with existing roof structures.
- ✓ Your project involves pool solar thermal systems, where Poco Solar Energy has specific documented experience with brands like Fafco panels.
- ✓ You value long-term warranty support and maintenance relationships, as evidenced by customers using their services for decades.
- ✓ You can accommodate potential scheduling delays and will proactively manage communication expectations given recent feedback about responsiveness.
Consider United Mechanical if...
- ✓ You have an existing relationship with United Mechanical from previous mechanical work and can verify their solar capabilities directly.
- ✓ You discover through direct contact that they have undocumented solar expertise and can provide references for solar projects comparable to yours.
- ✓ Your project involves mechanical systems integration where their broader mechanical background might provide value beyond pure solar installation.
Questions to Ask Before Hiring
- → Ask United Mechanical directly: What solar projects have you completed in the past two years, and can you provide three references for residential solar installations similar to mine?
- → Ask Poco Solar Energy: What is your current scheduling timeline, and how do you ensure communication responsiveness throughout the project given recent customer feedback?
- → Ask both companies: Who will be the point of contact for my project, and what is your process for handling questions or concerns during installation?
- → Ask both companies: What warranties do you provide on installation workmanship separate from manufacturer equipment warranties?
The Bottom Line
For solar work needed this week, Poco Solar Energy is the clear choice unless you can verify United Mechanical's solar credentials through direct contact. Poco Solar Energy brings 20 years of documented solar specialization, proven customer satisfaction across decades, and specific expertise in both pool heating and photovoltaic systems. Their communication challenges require attention but don't negate their technical competence. United Mechanical's complete absence of solar project history, customer feedback, or specialization claims makes them a high-risk choice without substantial additional verification. Contact Poco Solar Energy, address scheduling and communication expectations upfront, and move forward with a known solar specialist rather than gambling on an unproven option.

Frequently Asked Questions
This is a red flag worth investigating directly. A contractor operating for over two decades should have some form of customer feedback trail. They may focus exclusively on commercial work, subcontracting, or have recently entered the residential solar market. Before hiring, ask them to explain their review absence and provide verifiable solar project references.
Communication challenges are frustrating but manageable if you set expectations upfront. Ask specifically about current scheduling timelines and request a dedicated point of contact. Their technical expertise and decades of solar specialization remain intact. If you need white-glove responsiveness, address this directly during initial conversations and gauge their commitment to improvement.
No, both are veteran contractors with over 20 years of experience, making this difference negligible. What matters significantly more is documented specialization: Poco Solar Energy has proven solar expertise while United Mechanical has not demonstrated any solar project history despite their longer licensing period.
Solar installations require specific knowledge of electrical code, roof integration, system sizing, inverter technology, and utility interconnection procedures. While a mechanical contractor may have transferable skills, you need confirmation of actual solar training, manufacturer certifications, and completed projects. Without evidence of United Mechanical's solar capabilities, you cannot assume competence based solely on their mechanical license.

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.
