Why Choose a Whole House Generator?

The weather in Texas can be 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 down the road. Without power, your home has no lights, heating, or cooling, food can spoil, you can’t charge your devices, and you cannot access the 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. 

Let’s explore how our whole house generators can offer peace of mind in the face of these situations:

Reliability and Peace of Mind

In a city like Austin, where storms and power fluctuations are frequent, the assurance provided by a backup home generator is invaluable. Our standby generators kick into action automatically when the power goes out, guaranteeing your home stays comfortable and fully functional.

Safety for Your Family

A backup generator installed by one of our licensed electricians provides you with a reliable, worry-free backup power solution to keep you and your family safe. Our home generators ensure that devices such as oxygen and home dialysis machines operate without interruption. In addition to ensuring the uninterrupted operation of essential medical equipment, our generators keep home security systems active, providing continuous protection against potential risks such as intrusions, burglaries, and other security threats. This means that even during power outages, you can have peace of mind knowing that your home and loved ones are safe and secure.

Economic Benefits

Power outages can lead to significant economic losses, particularly for those who work from home or manage a home-based business. Our backup home generators minimize downtime and prevent costly damages to appliances and systems, helping you avoid financial setbacks.

Comfort and Convenience

Enjoy the peace of mind that comes with knowing your heating and cooling systems will remain operational during a power outage. Our home generator installation process not only preserves temperature-sensitive medications but also ensures that your daily routines can continue uninterrupted, creating a safe haven for you and your family during severe weather conditions.

Uninterrupted Connectivity

In today’s digital age, losing access to the internet, phones, and television can disconnect you from essential communications and emergency updates. Our backup generators maintain your connectivity, ensuring that you stay informed and in touch with the outside world.

Understanding Whole House Generators

Continuous Power with Generac:

Generac is a leading backup power industry brand known for its reliability and ease of use. Our Generac backup generators detect power outages automatically and activate within seconds, ensuring that your home’s electrical systems continue to operate smoothly.

Automatic Transfer Switch (ATS):

The automatic transfer switch is crucial in operating our backup home generators. It continuously monitors your utility power and, upon detecting an outage, safely disconnects your house from the grid and activates the standby generator. This means that 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 smartphone 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.

Fuel Options and Efficiency:

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.
