Keep Your Backup Power System Running Like New
Small issues like a clogged filter or low oil level might not seem urgent, but left alone, they can turn into major engine failures that cost a lot more to fix.
Generators keep sump pumps running, freezers cold, and sensitive electronics protected. Delays in fixing your system could mean water damage, food loss, or fried equipment.
For commercial properties, every hour without power is money lost. Quick generator repairs help you keep doors open and operations steady.
Especially during Houston’s brutal heat waves or heavy storms, you’ll want your AC, lights, and security systems running without pause.
We show up ready to troubleshoot. Our techs run quick but thorough tests on your electrical output, control settings, fuel delivery, and more to pinpoint exactly why your generator stopped working.
Most emergency issues can be handled right then and there. From swapping out dead batteries and blown fuses to clearing fuel lines and fixing sensor faults, we carry common parts and tools so we can get you powered up without delay.
If your issue needs a bigger repair, like a new starter motor or control board, we’ll lay it out clearly. No scare tactics or hidden fees, just straight answers on what’s wrong and how we can fix it.
Once repairs are done, we do a full test run. That means simulating a real outage, watching fuel flow, monitoring voltage, and making sure your generator can handle your property’s load without problems.
It Won’t Start: The most obvious sign. If your generator refuses to turn over when the power drops, you need help immediately.
Repeated Alarms or Error Codes: Blinking lights, fault messages, or beeping panels usually mean something serious is wrong inside your system.
Strange Smells or Smoke: Fuel leaks, overheating engines, or electrical shorts can all give off noticeable odors or even smoke. Shut the system down and call us fast.
Rough Running or Loud Noises: Knocking, grinding, or rattling sounds are often early warnings of mechanical problems that can quickly get worse.
Partial Power: If your generator runs but struggles to keep all your systems online, something might be off with load handling or voltage regulation.
Engine Damage: Running with low oil, bad filters, or a failing sensor can cause serious wear on your engine, shortening its lifespan or causing a complete breakdown.
Electrical Problems: Voltage issues can fry sensitive electronics in your home or business. Quick repairs keep your systems safe.
Fuel Hazards: Leaks or bad connections in propane and natural gas lines are dangerous. Fixing these right away keeps your property and people safe.
Water Damage: If your sump pump goes down during a storm, it can lead to basement flooding and expensive cleanup. Keeping your generator operational stops that risk.
While we’re always ready to help in a crisis, most generator failures can be avoided with simple habits. Here are a few ways to cut down on late-night emergency calls:
Run Monthly Tests: Let your generator run for five to ten minutes every month. This keeps fluids moving, charges the battery, and highlights problems early.
Keep It Tidy: Clear leaves, branches, and clutter from around your unit so it can breathe properly and avoid overheating.
Watch for Changes: Stay alert for weird noises, new smells, or flashing alerts on your control panel. They’re your generator’s way of telling you something’s wrong.
Log Your Runs: Keep a quick notebook or digital record of test runs, power outages, and maintenance visits. Patterns can reveal problems before they get serious.
Or just let us handle it, AstroGen’s maintenance plans include scheduled inspections and service reminders, so you’re always ahead of the game.

“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
