Home Backup Generators

Whole Home Backup Generator Installation Solutions in San Antonio

Home backup generators keep the lights on when power goes out.

A power outage can be inconvenient if it only lasts a few hours, but it can be devastating if you’re without power for several days—or worse, longer! Fortunately, Generac home backup generators are there to keep your home’s electricity on even when the utility company power goes out, keeping your lights on and your food from spoiling.

Emergency Backup Power

Life changes when utility power fails. During a power outage, your home has no lights, heat, or central air. Your refrigerator, microwave, laundry equipment, Internet, and television are rendered useless. We tend to take these conveniences for granted because they’re always available to us. But what happens when they are not? Unfortunately, it’s happened to all of us—and when it does, it’s scary. That’s why purchasing a home backup generator can be such a good idea; not only do these systems provide backup power in case of emergency, but they also prevent that panic that sets in during an outage. Remember the February 2021 freeze? With a standby generator, you’ll have light and heat and won’t need to drive around looking for someone who might let you use their electricity.


What Is the Best Location for my Backup Generator?

For a backup generator to be useful, it has to power your home during a power outage. Our recommendation is to connect it to your existing natural gas fuel supply and wire it into your primary electrical panel.  Within seconds of the automatic transfer switch sensing utility power loss, the generator starts automatically and runs until the utility power is restored.

Do I Need Profession Installation?

In addition to purchasing a backup generator, you’ll need a licensed plumber and electrician to properly install these services.  If you don’t know what you’re doing, there is potential for your generator system to be plumbed or wired improperly which can lead to potential fire hazards. And of course, it’s always best to hire someone who knows generators inside and out to assure proper operation.  Professional installation the first time is always less expensive than correcting a mistake.

Why Choose a Generac Generator?

Generac is the most trusted and reliable manufacturer of home standby generators in the world. Since 1959, more than 2 million Generac generators have been installed across the country.

With up to 24,000 running watts, Generac generators are designed with your family’s safety and comfort in mind.
