Customer Reviews
GAF Energy
Overall, a good experience if you go in with measured expectations. The process from signing the agreement to PTO is a long one, but the work was done professionally, and so far production is exceedin...
We are sharing a photo of the front view of our house and a close up view of the solar roof in this review. The solar roof is fully functional and looks elegant. Best of all, we had GAF Energy as th...
GAF team is great! The project manager Aidan is professional and efficient. He always answered our questions/concerns promptly. We are glad to choose GAF solar roof.
Modern Air
We replaced all of our asbestos-wrapped ductwork and installed a new heat pump system in late October. The entire Modern Air team did a great job with this relatively large project. Andrew, the owner...
Outstanding! Professional! Efficient! Great communications! Same day service. Texts and emails confirming all communications. Installation several days later. A special thanks to Billy, Alfredo and hi...
Alfredo was professional and courteous, and so was the previous person who came out for quote. Modern Air does a great job with their client communications, and their cost is reasonable.
Consider GAF Energy if...
- ✓ You need a combined roofing replacement and solar installation project and specifically want integrated solar shingles rather than traditional rack-mounted panels
- ✓ You're prepared to manage a multi-phase project timeline including permitting delays and utility coordination that may extend several weeks beyond installation
- ✓ You have patience for potential post-installation communication delays and are comfortable being proactive in follow-up for system activation
- ✓ Your roof needs replacement anyway and you want to integrate solar in a single project rather than two separate contracts
Consider Modern Air if...
- ✓ You need HVAC services including furnace or air conditioning repair, system replacement, heat pump installation, or ductwork work
- ✓ Responsive communication and same-day service availability are priorities for your comfort and timeline
- ✓ You value transparent diagnostics without pressure to purchase unnecessary upgrades or equipment
- ✓ You want a contractor with nearly two decades of experience diagnosing problems with both older legacy systems and modern high-efficiency equipment
Questions to Ask Before Hiring
- → For GAF Energy: Ask specifically how post-installation support works, who your direct contact will be for activation issues, and what their typical response time is after the system is installed but before it's activated
- → For GAF Energy: Request a detailed timeline showing expected duration for each phase including permitting, installation, inspection, and utility interconnection approval
- → For Modern Air: Confirm whether they service your specific equipment brand and ask about parts availability for your system age
- → Ask both contractors for references from projects completed in the past six months to verify current service quality
The Bottom Line
These contractors serve completely different needs, so your decision depends entirely on your project type. If you need HVAC work, Modern Air is the clear choice with 17 years of experience, consistently positive feedback for responsive communication, and a track record of honest recommendations without upselling. If you specifically need integrated solar roofing, GAF Energy offers that specialized service with professional installation teams, but prepare for potential communication delays after installation and be ready to proactively manage the activation process yourself. Do not expect the same responsiveness that Modern Air customers report. If you're planning both solar and HVAC upgrades, hire them separately for their respective specialties rather than expecting overlap in services.

Frequently Asked Questions
You wouldn't under normal circumstances, as they serve completely different needs. If you're seeing this comparison, you may be researching multiple home improvement projects simultaneously or exploring whether to bundle solar with HVAC upgrades for energy efficiency. These contractors don't compete with each other; they operate in separate trades entirely.
The experience gap is meaningful, but context matters. Solar roofing integration is a relatively newer specialty compared to HVAC work, so six years represents reasonable experience in that specific market. However, 17 years provides substantially more exposure to problem-solving unusual complications, which matters for complex projects. The bigger concern with GAF Energy isn't experience level but the consistent feedback about post-installation communication difficulties.
High owner involvement typically means more direct accountability and consistent service standards across all jobs. Customers report clear communication and honest recommendations without upselling, which suggests the owner maintains close oversight of customer interactions. For HVAC service calls where you need quick, trustworthy diagnostics, this involvement level provides reassurance that you're getting the company's best judgment rather than commission-driven sales pressure.
Customer feedback identifies this as a recurring pattern, not isolated incidents, particularly during the activation phase when homeowners need utility coordination support. This matters because your solar system generates no savings until it's activated and connected to the grid. If you choose GAF Energy, plan to be proactive in follow-up communication and document all interactions. Ask upfront who will handle activation coordination and get direct contact information before installation begins.

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.
