We're Not a Valley Company That Drives Up the Hill
When you call most generator companies in the Inland Empire, you're talking to a business based in Redlands, San Bernardino, or Riverside — a company that will send a crew up the mountain for your installation and then return to the valley. They don't know that CA-138 closes in heavy snow. They don't know that the driveway at your Cedar Glen cabin is only accessible with a smaller truck. They don't understand why your installation needs to account for 6 feet of annual snowfall or why the concrete pad needs to be elevated above the typical snow line.
Mountain Top Generator is different. We are based at 25266 CA-18 in Crestline, at 6,500 feet in the San Bernardino Mountains. Our team lives in the communities we serve — Lake Arrowhead, Running Springs, Twin Peaks, Skyforest, and the rest of the Rim of the World corridor. We don't just install generators here; we depend on them ourselves.
The First In-House Generac Dealer on the Mountain
Mountain Top Generator was founded in 2025 with a specific mission: to bring authorized Generac sales and installation to the mountain communities that need it most. Before we opened, residents of Lake Arrowhead and Crestline had to work with valley-based dealers who charged significant travel fees, had long lead times, and often sent technicians unfamiliar with high-altitude installation requirements.
As an authorized Generac dealer, we carry genuine Generac products, provide factory-backed warranties, and have access to Generac's technical support and parts network. We are not a third-party installer buying generators from a wholesaler — we are a direct Generac partner.
Everything In-House, Nothing Subcontracted
Many generator companies subcontract the concrete work to one crew, the gas line to a plumber, and the electrical to an electrician — leaving the homeowner to coordinate between multiple contractors and wonder who is responsible when something goes wrong. Mountain Top Generator handles everything in-house: concrete, gas, electrical, and final commissioning. One company, one point of contact, one warranty.
Our team is fully licensed and insured in all required trades. We pull all required permits, coordinate all required inspections, and stand behind our work with a comprehensive installation warranty in addition to Generac's 5-year product warranty.
Service After the Sale
The relationship doesn't end at installation. Mountain Top Generator offers comprehensive service agreements that cover annual maintenance, priority scheduling for service calls, and remote monitoring through Generac's Mobile Link™ dealer portal. When your generator needs attention, you call a local number and talk to someone who knows your installation — not a national call center.
