What to Expect From GenerX Generators?
Backup power generation is more important than ever. Every day, our world gets more fast-paced, our work becomes more reliant on power, and it becomes more necessary to have a plan for staying powerful no matter what. As more families look for reliable backup power, wait times increase. That means that planning ahead for your generator installation isn’t just advisable – it’s necessary.

“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!”
