Happy Customers

"Mark Costis and the Generx team keep my whole house powered in case of city power outages. They have the greatest service and excellent products. With a full tank of propane (250 gallons) I can run my whole house for at least a week. Thanks Mark! A Generx Generator was a great investment!"

Adil

"Irma would've been an even bigger nightmare without our generator--it's officially my new favorite thing, and I'm grateful for the work you're doing in the Tampa Bay area."
