Dependable Backup Power for Homes and Businesses
Losing electricity can quickly become more than an inconvenience. From spoiled food and dead outlets to stalled workdays and safety risks, power outages in Houston are disruptive at best and damaging at worst. Whether the culprit is a summer storm, an overloaded grid, or surprise utility work, one thing is clear: you need a plan when the lights go out.
At AstroGen, we install dependable, fully automatic standby generators for homes and commercial properties throughout Houston and cities like Humble, Katy, Cypress, The Woodlands, and Sugar Land. Our systems switch on in seconds when the power fails, no cords, no waiting, and no stress. Whether you’re setting up a new system or replacing an aging unit, we handle it all: site planning, permitting, fuel hookups, transfer switches, and full installation.
When you want backup power you can count on, we’ll help you choose the right system, install it with precision, and make sure it’s ready when you need it.
Most folks wait until after the first blackout to consider a generator. But if you’ve ever gone without power for more than a few hours, you know how fast the situation can turn. Here’s why investing in a standby system is worth it:
Keep Life Moving: Your fridge stays cold, lights stay on, HVAC runs, and smart devices keep working. A generator keeps your daily routine running like normal, even when the grid goes down.
Protect Critical Systems: Sump pumps, alarm systems, and medical devices stay operational, avoiding costly or dangerous disruptions. That means fewer emergencies and less damage when power outages strike.
No Manual Startups: Unlike portable models, standby generators turn on automatically. You don’t have to lift a finger. The system handles everything within seconds of an outage, so you’re never scrambling.
Boost Property Value: Homes with built-in generators attract buyers looking for safety and security. It’s a long-term upgrade that adds both comfort and resale appeal.
Peace of Mind Year-Round: Houston weather is unpredictable. Your power shouldn’t be. With a standby system, you’re ready for storms, heatwaves, and anything in between.
Getting a generator installed the right way takes careful planning and expert execution. At AstroGen, we follow a detailed process to make sure your system is safe, efficient, and ready for the long haul.
We kick things off with a walk-through of your home or business. Our team reviews your current electrical setup, discusses which appliances and systems you want backed up, and helps determine the ideal generator size.
Next, we help you choose a system from trusted manufacturers like Generac, Kohler, or Briggs & Stratton. We’ll coordinate placement, review local code, and line up the gas or propane connection plan.
We install a stable base for your generator—either a new concrete pad or an existing platform. Then we run all the necessary wiring to your main panel and fuel line, making sure everything is secure and up to code.
The transfer switch is what allows your system to shift automatically when the power drops. We install it at your panel, ensuring a smooth and seamless transition during any outage.
Once everything’s hooked up, we simulate a power outage to test fuel flow, switch timing, and load handling. We don’t leave until we’re confident your generator is ready to perform.
We offer ongoing service options to keep your system in peak shape. That includes oil changes, software updates, battery testing, and annual inspections.
Our clients across Houston trust AstroGen because we show up when we say we will, install cleanly, and make sure their generators are truly ready. Whether it’s a small home system or a large commercial setup, we treat every project with care and precision.

“Our power went out during a storm that came through during the night and we lost power. Our Generac generator didn’t startup and threw errors. I called around 9:00 am and the owner, Mason, showed up within the hour and was so great working with us. Unfortunately we have to get the motor replaced, Mason took care of calling Generac to work on getting it replaced through our warranty. We can’t say enough good things about the service we received. We will be using them now on for routine service maintenance. I HIGHLY recommend them.” – Stacy ONeal
“The installation crew was respectful and did a phenomenal job from install to clean up. The service tech came out the next day and did a complete walkthrough with me and answered every question I had. Best choice I made by using Astro Gen to service my house!!! Thank yall again.” – Roman McElfresh
“AstroGen successfully completed the installation and start up of my whole-home generator. I chose Cummins Generator. I am super pleased with the process, the workmanship and the people. I would particularly like to mention @Jose, and @Ethan who were directly responsible for the installation, both are nice and professional, and Caleb who was my main point of contact. Overall, I am satisfied with AstroGen. I have already recommended AstroGen to my neighbor who is scheduled to get his installed in a few weeks.” – Dharmesh Shah
“There are very few companies that truly deserve more than 5 stars. This is one of them. I tried to get generator quotes from several companies. And AstroGen was the only one that got back to me in a timely manner. From the first phone call they were organized, professional and transparent. Kaden came out for out house quote and walked us through options, answered all of our questions and made sure we felt comfortable. Install day was today (even after major storms last night), everything was completed on time and the owner Mason came out and looked everything over and did the final walkthrough. I could not be more appreciative of AstroGen and their team! I would highly recommend to anyone and everyone.” – Cameron Branham
Still on the fence? Here are a few signs it might be time to invest in a permanent backup system:
Frequent Power Interruptions: If you’ve experienced more than one or two outages in the past year, chances are you’ll face more. Generators protect your home from being caught in the dark again.
Medical Equipment at Home: If anyone in your household uses powered oxygen, dialysis, refrigerated medications, or mobility devices, reliable electricity is not optional.
You Work from Home: Losing power during the workday can mean missed deadlines, dropped video calls, or even lost revenue. A standby system helps you stay connected and productive.
High Appliance Use: Refrigerators, HVAC systems, sump pumps, smart locks, and garage door openers all rely on consistent power. Generators protect your gear and your comfort.
You’ve Had Property Damage from Outages: If you’ve dealt with flooding from a failed sump pump or a false alarm from a dead security system, a generator can help prevent those headaches in the future.
A lot of folks hold off on installing a generator because of common misconceptions. Here’s what we hear, and what’s actually true:
“Portable generators are good enough.”
Not really. They need to be wheeled out, filled with fuel, manually started, and managed in real time. A standby unit handles all of that on its own.
“They’re expensive to run and maintain.”
With routine checkups and modern tech, today’s systems are efficient and low-maintenance. Most need an annual service and that’s it.
“We rarely lose power, it’s not worth it.”
Even one long outage can cause food loss, system failures, and security risks. Generators are about peace of mind, not just convenience.
Already have a generator but not sure if it’s working like it should? Here’s how we can help:
Generator Repairs: If your current system just needs a new battery, a tune-up, or a wiring fix, we can usually get it back up and running fast. We service most major brands and can run diagnostics to figure out what’s wrong.
Generator Replacement: Older systems, especially those over 10 years old, can start breaking down more often or fail to meet modern power needs. If repairs are piling up or your home has grown, we’ll help you upgrade to something more powerful and efficient.
Honest Advice: We’re not here to upsell you. Our team will inspect your system, explain your options, and give you clear pricing, so you can make the decision that feels right.
Standby generators are built to last, but like any machine, they need regular care to stay in top shape. A well-maintained system performs better, runs longer, and gives you peace of mind every time the power goes out. Here are some simple tips to help extend the life of your generator and keep it ready for anything:
Run It Monthly: Set your system to run a short self-test every month. This keeps parts lubricated, charges the battery, and helps you spot issues early.
Check for Visible Wear: Take a quick look at your generator every few weeks. Look for loose wires, rust, pests, or signs of fuel leaks.
Keep It Clean and Clear: Clear away debris, leaves, and anything blocking airflow around the unit. Generators need proper ventilation to avoid overheating.
Monitor Oil and Coolant Levels: If your unit doesn’t have automatic alerts, check oil and coolant levels manually every few months, or after extended run times.
Change the Oil and Filters Annually: Just like a car, generators need oil changes. Replacing oil, air, and fuel filters yearly helps the engine stay efficient and reliable.
Inspect the Battery: Batteries can lose charge over time, especially in Houston’s hot climate. Test voltage regularly and replace weak batteries before they fail.
Schedule Professional Service: Even if everything seems fine, a yearly inspection by a licensed technician is key. We’ll check connections, update software, test components, and keep your system code-compliant.
