Why Every Texas Household Should Consider Installing a Standby Generator

Summer hits Texas with everything from tornadoes to hurricanes to torrential rains, high winds, heat, and drought.

In 2025, we had more than twice as many dangerous thunderstorms as the next highest state, and more than a million lightning flashes above the state average, making Texas the state with the most lightning strikes.

The data matter because severe storms, lightning, and high winds can cause power outages. In fact, Texas ranks second for the most power outages in the U.S.

At Beyer Air Conditioning and Heating, we recommend an outage solution that every Texan should consider: a standby generator. It’s the best way to ride out power loss—with appliances, home systems, lighting, and outlets all working normally.

Standby generators use natural gas or propane and are unaffected by electrical power grid issues. High winds and falling tree limbs that interfere with power lines won’t stop your standby generator from operating. Lightning strikes to electrical infrastructure and even brownouts are no match for your equipment.

At Beyer Air Conditioning and Heating, we believe in helping you stay prepared. If you’ve been wondering whether a standby generator is right for your home, take a look at this summer’s power outlook and why you may need whole-home backup power.

Is the Texas Power Grid Reliable?

The Electric Reliability Council of Texas (ERCOT) anticipates increased demand this summer but says it will have sufficient power, and adds that the risk of rolling blackouts is low. Even so, the grid faces increasing demand from data centers, computing facilities, and home air conditioners that work 24/7 as nights stay warm rather than cooling off.

Add extreme weather to the mix, and it’s no wonder Texans are looking for a solution that won’t leave them in the dark during the summer heat and winter cold.

How a Standby Generator Works

Unlike a portable generator, a standby generator is a permanent, automatic fixture for your home. It sits outside, much like your central air conditioning unit, and stays on standby 24/7, constantly monitoring your home’s utility power.

Within seconds of an outage, the system’s automatic transfer switch (ATS) signals the generator to start, and it seamlessly transfers your home’s power supply from the grid to the generator. When utility power is restored, the generator automatically shuts itself down and returns to standby mode.   

Portable vs. Standby vs. Backup Generators

Some homeowners prefer portable generators because they cost less than standby units. But they do have several disadvantages. If the power goes out during a storm, you’ll end up either waiting it out or connecting your portable generator in bad weather. You’ll use extension cords to connect the generator to indoor appliances, and you will manually refill the equipment with fuel. If you aren't home to start a portable generator, your home remains powerless.

A backup generator is more convenient than a portable unit because it plugs into an inlet box  installed on your home’s exterior and does not require extension cords. The box is hardwired to a manual transfer switch near your electrical panel. This type of generator requires several manual steps to start and route power safely to selected circuits.

At Beyer Air Conditioning and Heating, we understand that homeowners prefer choices when selecting a generator. That’s why we install and maintain standby generators, as well as portable and backup units.

Does a Standby Generator Work During a Brownout?

One of the greatest benefits of a standby system is its ability to handle brownouts. A brownout is a drop in voltage rather than a total loss of power. You might notice your lights dimming or appliances barely working.

Most standby generators feature built-in protection that monitors these fluctuations, ensuring your home remains powered by stable energy instead of struggling with brownouts.

Why You Need Reliable Backup Power in Boerne

A standby generator is an essential investment in your home as the weather becomes more unpredictable from year to year and development demands more of the power grid.

Beat the Heat: We know that extreme heat is dangerous for your well-being. A standby generator ensures your HVAC system continues to keep your home cool during record-breaking summer temperatures.

Health and Safety: A standby generator is a lifesaver for families that rely on powered medical equipment. It also keeps your security system armed and your lighting on, keeping your family safe when the neighborhood goes dark.

Property Protection: Extended outages can spoil groceries in your refrigerator, and if you have a basement or low-lying areas, a failed sump pump can quickly cause water damage.

Reliability: Because these units run on your home’s existing natural gas or propane supply, you don’t have to worry about storing gasoline or refueling during a storm. A standby generator works whether you are home, at work, or on vacation, giving you peace of mind.

FAQs About Standby Generators

How loud are home standby generators? 

Most standby generators operate at the same volume as central air conditioning units.  Portable units are much louder.

Can a standby generator replace my utility service? 

No. Standby generators provide backup power only when the utility grid is down.

How do I know what size generator I need? 

Sizing depends on your square footage, the appliances you want to run, and your power requirements. The best way to determine the right fit is by scheduling an in-home visit with our Beyer Air Conditioning and Heating team.
