Testimonials are the difference between a prospect clicking away and picking up the phone to schedule a generator installation. When potential customers see real stories from homeowners or businesses who've actually dealt with power outages, they're far more likely to trust you with a five-figure investment.
Why Testimonials Outsell Everything Else
Generic marketing claims don't move the needle. A homeowner worried about backup power during storm season responds to another homeowner's story about staying comfortable through a 72-hour outage. Video testimonials and written reviews create social proof that your sales page, brochures, and ads simply cannot match.
Testimonials do three things at once:
- Address real fears (installation complexity, cost overruns, reliability in emergencies)
- Demonstrate your service quality through independent voices
- Improve local SEO when posted on your website and Google Business Profile
Gathering Testimonials From Installation Customers
The best time to ask for a testimonial is 2–4 weeks after installation, once the customer has used the system through at least one weather event or routine maintenance cycle. They've had time to experience the generator's performance and your after-sales support.
Make it friction-free. Don't ask for a novel. A 2–3 sentence reflection on what they worried about before installation and what changed afterward works beautifully. You can even send a simple template:
- "What problem did you face before installing the generator?"
- "How has it changed your peace of mind?"
- "Would you recommend us, and why?"
Offer to handle the logistics—send them a short video questionnaire they can answer on their phone, or conduct a quick phone call you can transcribe. Many customers will participate if you remove the friction of writing.
Specific Testimonial Angles for Generators
Different customer segments need different reassurance. Tailor your collection strategy to capture these angles:
Residential whole-home systems ($15,000–$35,000 installations): Focus on peace of mind, reliability during extended outages, and ease of use. Homeowners care about whether the system actually works when they need it.
Small business/commercial backup ($8,000–$50,000+): Highlight business continuity, uptime during critical operations, and ROI. A small clinic, server room, or retail operation has quantifiable losses from downtime.
Service and maintenance testimonials: Don't overlook ongoing customers. A testimonial from someone who's used your annual maintenance plan for three years is gold—it proves reliability and customer retention.
Installation speed and professionalism: Customers appreciate when complex jobs stay on schedule. A testimonial about a three-day installation that finished on time with minimal property disruption resonates with nervous prospects.
Displaying Testimonials Where They Convert
A testimonial buried on your "About Us" page reaches almost no one. Put them where prospects are making decisions:
- Homepage hero section: Feature a video or bold quote from a satisfied customer with a photo and name
- Service pages: Match testimonials to specific generator types (standby, portable, transfer switch upgrades)
- Google Business Profile: Respond to and encourage reviews; respond to negative ones professionally
- Before-and-after case studies: Pair a short testimonial with photos of the installation and a brief breakdown of system specs and cost
- Email sequences: Use customer stories when following up with leads who haven't converted yet
Video testimonials perform 80% better than text. Even a 30-second phone video of a customer speaking directly about their experience will outperform polished ad copy.
Building Long-Term Testimonial Assets
Create a system for collecting and organizing testimonials:
- Set calendar reminders to request feedback 3 weeks post-installation
- Keep a spreadsheet of all testimonials with contact info, approval status, and which marketing channels use them
- Refresh testimonials annually—older ones lose credibility
- Ask permission to use customer names and photos; offer a small discount on maintenance for video participation
Listing your generator services on Mercoly helps you get found by high-intent customers, but testimonials turn lookers into buyers and increase your conversion rate significantly.
Frequently Asked Questions
Q: How long should a generator installation testimonial be? Two to three sentences is ideal—long enough to be credible, short enough to actually get read. Focus on one specific benefit or concern that was resolved.
Q: Can I use testimonials from customers who are still paying off their installation on a payment plan? Yes, absolutely. In fact, financing testimonials work well because they address affordability concerns. Just make sure the customer is happy with the system itself, not just the payment terms.
Q: What should I do if a customer refuses to give a testimonial? Don't push. Instead, ask a simpler question: "Would you recommend us to a friend?" If they say yes, that's a lead magnet—ask if you can mention that in your marketing with no identifying details.
