Texas weather is unpredictable and power outages do happen

In many cases power outages only last a short while, but that’s precious time lost that may end up costing you even more money. Your home without power has no light, heating or cooling, food can spoil, you can’t charge your devices and no internet / TV or radio to get important news. More importantly, if you run a home business you may end up losing revenue from being non-operational.

How does an Electrical Standby Backup Generator work?

A backup generator for your home can run on either Propane or Natural Gas. Both options are energy efficient and with automatic operation. Within seconds of a power failure, the generator will switch on providing your home with basic electrical power (see chart below) and will turn off automatically once your utilities have been restored. A complete electrical inspection by licensed electricians is recommended before choosing a backup generator.


During a power outage you won’t need to run outside and pull-start the generator – it’s completely automated. You can even monitor the status of your generator from anywhere using your smart phone or tablet.

Additionally, most Generators automatically “exercise” themselves once a week, starting and stopping to ensure they’re ready to go in case of a power outage. This is done without any interruption to your home’s power.
