Reliable Repairs That Keep Your Backup Power Ready
Generators are built for emergencies, but even the best systems can fail without warning. From delayed startups to fuel issues, unexpected shutdowns to error codes, small problems can leave you without power when you need it most. That’s where AstroGen comes in.
Our licensed Humble-based team handles generator repair for homes, commercial properties, and critical facilities across the Houston area. Whether it’s a recent install, an aging unit, or a generator that just stopped working, we’ll inspect, troubleshoot, and repair it the right way, so you’re not left in the dark.
We also handle maintenance, emergency response, upgrades, and more, everything you need to keep your backup power dependable, no matter the season.
It might start as a flickering panel or a skipped test cycle, but even small generator issues can become serious fast. When your system fails, you lose more than just lights, it can impact your comfort, security, and property safety. Here’s why prompt repairs matter:
Protect Critical Systems: Backup generators keep fridges, medical equipment, HVAC systems, and security devices powered. When they fail, your essentials go offline.
Prevent Costly Damage: Fuel leaks, faulty wiring, or dead batteries can cause electrical damage or even pose fire risks. Getting ahead of problems saves money and stress.
Extend Equipment Life: A generator that gets regular attention runs smoother and lasts longer. Small fixes now can add years to your system’s lifespan.
Stay Ready for Anything: Houston’s power grid isn’t always reliable. Storms, heatwaves, and grid overloads hit without warning, your generator should be ready when it counts.
We take a clean, step-by-step approach to identify and fix your generator issues without unnecessary guesswork.
We start with a thorough inspection of your generator, checking for signs of wear, fuel issues, battery failure, and wiring problems. If your unit has digital controls, we’ll pull diagnostic data too.
Next, we identify the source of the problem, whether it’s a starter motor, a clogged fuel line, a sensor failure, or something more complex. We don’t guess, we test.
Once we find the issue, we walk you through the fix. No jargon, no scare tactics, just clear, honest recommendations about what needs to be done and why.
From battery swaps and fuse replacements to control board reprogramming, we handle most repairs on the spot. If your system needs parts, we’ll source them fast and schedule a return visit right away.
We don’t pack up until your generator runs exactly like it should. That includes test starts, full power cycles, and fuel flow checks to confirm performance.
Generators are quiet until they are not—but these signs usually show up before a major failure:
Startup Delays: If your generator takes longer than a few seconds to start during a test cycle, something is slowing it down, and it might not start at all during an outage.
Unusual Noises: Knocking, buzzing, or loud rattles while running are early warnings of mechanical or internal damage.
Leaking Fuel or Fluids: Even small drips from fuel lines or coolant hoses need immediate attention. Left unchecked, they create bigger problems, and safety hazards.
Dashboard Warnings or Error Codes: Blinking lights, error messages, or strange system alerts usually point to failing sensors or electrical faults. We can clear these up and fix the cause.
Low Power Output: If your system powers down too soon or can’t handle normal loads, something is misconfigured or underperforming. We’ll help you get it back to full strength.
Tackling generator repairs yourself might sound like a money-saver, but it usually leads to bigger problems. Here’s why calling a professional is the better move:
High Voltage Is No Joke: Generators store and deliver serious electrical power, even when they’re off. A wrong touch can cause a dangerous shock or damage your electrical system.
Today’s Systems Are Complex: Modern standby generators use smart controls, sensors, and software. Without proper training, it’s easy to misdiagnose the issue or make things worse.
You Could Void the Warranty: Most generator warranties require certified service for repairs. One DIY attempt could cancel your coverage and leave you on the hook for costly fixes.
Fuel Line Mistakes Are Risky: Generators often run on propane or natural gas, which can be hazardous if mishandled. A bad connection or loose valve can lead to leaks or fire risk.
You Might Only Fix Part of the Problem: Replacing a battery or fuse might seem like a solution, but deeper electrical or fuel issues could still be lurking. Licensed techs know how to spot and solve the real cause.
It Can Cost More in the Long Run: DIY jobs often need to be redone, or corrected, by a professional later. That means paying twice and losing time when you need your generator most.
Not every generator is worth saving. If your system is aging, unreliable, or just not cutting it anymore, it might be time for a replacement. Consider a replacement if:
Your unit is over 10–12 years old: Older systems lose efficiency, struggle with reliability, and may no longer meet modern electrical demands. Upgrading gives you better performance and peace of mind.
It needs constant repairs or resets: If you’re calling for service more often than not, your generator may be reaching the end of its life. Frequent issues add up in cost and downtime.
It no longer supports your appliances or square footage: If your home or business has grown but your generator hasn’t kept up, it could be undersized. A properly sized system keeps everything running smoothly without overloads.
You want newer features like remote monitoring or quieter operation: Today’s generators come with smart tech, sound-dampening, and more energy-efficient performance. Upgrading means better control, quieter function, and improved convenience.
