Generator Maintenance in San Antonio, TX
Prevent Problems Before They Start with Proactive Generator Maintenance
A standby generator is only as reliable as its last service. At Synergy Standby Solutions, we provide expert generator maintenance in San Antonio, TX & the surrounding areas that keep your system ready for anything — whether it’s a routine outage or a major storm.
Serving both residential and commercial clients, we help you avoid costly repairs, extend the life of your generator, and ensure your backup power system performs exactly when you need it.
Why Regular Generator Maintenance Matters
Standby generators are built to perform under pressure — but they can only do their job if they’re properly maintained. Just like a vehicle, these systems contain moving parts, electrical components, and fuel systems that degrade over time. Without routine checkups and preventative care, even the most reliable generator can fail when you need it most.
Here’s what can happen without regular maintenance:
Startup failure during a power outage
Battery degradation
Fuel contamination or leakage
Mechanical breakdowns
Poor load handling and performance
At Synergy Standby Solutions, our preventative maintenance service is designed to catch problems early, extend the life of your equipment, and ensure your system performs flawlessly in any emergency. It’s one of the smartest and most cost-effective ways to protect your investment — and your peace of mind.
What’s Included in Our Generator Maintenance Service
Whether you rely on a home standby generator to protect your family or operate a commercial-grade system for critical business operations, proper maintenance is essential. At Synergy Standby Solutions, we offer thorough, detail-oriented service visits that keep your system in peak condition.
Here’s what you can expect with every maintenance appointment:
We perform a top-to-bottom inspection of your generator unit, including wiring connections, fuel lines, enclosures, sensors, and control panels. Our technicians look for signs of wear, corrosion, leaks, or damage that could affect performance or safety.
Like any engine, your generator depends on clean oil and proper filtration to run smoothly. We drain old oil, replace oil and air filters, and refill with high-quality lubricants that meet manufacturer specs — extending the life of your engine and improving efficiency.
A generator is only as good as its battery. We test voltage levels, inspect terminals for corrosion, and check charging functionality. If your battery shows signs of degradation or risk of failure, we’ll recommend replacement before it becomes a problem.
Our team inspects coolant levels and tests for proper flow and temperature control. For fuel systems, we look for contamination, water intrusion, and leaks that could affect combustion or cause performance issues — especially in diesel or natural gas systems.
The automatic transfer switch (ATS) is what tells your generator to kick on when utility power fails. We inspect the switch’s wiring, sensors, and contact points to ensure quick, seamless transitions when an outage occurs.
For businesses and facilities with high energy demands, we conduct load bank testing to simulate real-world operating conditions. This verifies that your generator can handle your full load without voltage drops, delays, or faults — keeping your critical systems protected during real emergencies.
Modern generators often rely on digital controllers. We check for manufacturer-issued updates to firmware or monitoring software and ensure your system’s technology is running the latest, most stable versions for improved accuracy and responsiveness.
