The Generac / Honeywell Advantage:

While portable generators may seem convenient, an automatic standby generator is a far wiser choice. 
Below are just a few reason to choose a Generac / Honeywell installation.

  • ​Our Units run on natural gas or propane, both of which are far less costly than gasoline.

  • As soon as the power goes out, an automatic standby generator will start running, whereas a portable unit requires considerable setup time and several extension cords to properly supply your home or business with power.

  • Our units provide 24/7 protection - even if you're away from your home or business

  • The American Red Cross recommends automatic standby generators and warns against the hazards of portable generators.

Commercial Generators:

For a small business, the loss of revenue sustained from a power outage can be crippling.

Even a few hours of downtime could mean substantially fewer customers and the potential for damaged ​equipment and goods.

Installing a Generac generators is a wise investment - after providing energy for just one outage, it may even pay for itself.
