The Benefits of Generac Generators

Why choose a Generac brand generator for your home or business in Gaithersburg? It’s all in the perks of course, and Generac offers many:

  • Reliability. Generac isn’t at the top of the industry for no reason! Generac generators are built to perform and to last, helping you stay secure in your home for years to come.
  • Solid warranties. Generac offers extensive warranties for generators that receive routine maintenance services, so you know you’ve got a product you can trust.
  • Fuel options. Choose between propane or natural gas according to availability and personal preference.
  • Versatile generator solutions. Generac offers generators in a wide array of sizes, everything from small portable units to simply keep lights or a fridge running, all the way to systems that can power an entire home without any trouble at all.
  • Automatic transfer availability. Automatic transfer switches will instantly swap over your home from utility power to your home generator without so much as a blink, making accessing generator power quick and safe.

Transfer Switch for Your Portable Generators

A transfer switch allows you to connect a portable generator to your household circuit breaker. It makes it possible to power all critical appliances permanently connected to your house grid. It is the best solution that follows all building codes and safety measures.

Backup Generators for Whole-House Purposes

A permanently installed Generac whole-home backup generator protects your home automatically. It runs on natural gas or liquid propane (LP) fuel, and it sits outside just like a central air conditioning unit.
