Common Generator Problems and Backup System Essentials

Even the best standby generators can experience wear, damage, or system failure, especially in San Antonio’s demanding climate. At Evenflow Home & Commercial Services, we provide expert diagnostics, timely repairs, and in-depth system checks to ensure your backup power works flawlessly when you need it.

Generator Issues We Commonly Repair

• Failure to Start During Outage: A generator that won’t kick on can be due to a dead battery, fuel delivery issue, or controller malfunction.
• Frequent Alarms or Error Codes: Alerts from your system may indicate voltage fluctuations, blocked air intakes, oil pressure problems, or controller software bugs.
• Low or Fluctuating Voltage Output: Inconsistent output can damage electronics and typically results from worn brushes, voltage regulator failure, or loose wiring.
• Overheating: Dirty air filters, restricted ventilation, or coolant problems can cause overheating and automatic shutdown.
• Delayed Transfer Switch Operation: If your generator doesn’t switch over right away, the transfer switch could be misconfigured or aging.
• Leaking Fluids (Oil, Coolant, Fuel): Leaks indicate broken seals, loose fittings, or damaged hoses, all of which can compromise operation.
• Unusual Noises or Vibrations: Loud knocking, buzzing, or shaking may suggest mechanical wear or unbalanced load distribution.

Our expert technicians are trained to service all major generator brands, ensuring every component, from the fuel line to the digital controller, operates safely and efficiently.

What Makes a Standby Generator System Work

A complete backup power system includes more than just a generator. These key components must be installed, configured, and maintained properly:

• Standby Generator Unit: The main power source, designed to automatically engage when utility service is interrupted. Powered by propane, natural gas, or diesel.
• Automatic Transfer Switch (ATS): Detects the loss of power from the grid and switches your home to generator power within seconds. Also returns to grid power when it is restored.
• Fuel Delivery System: Supplies consistent fuel via direct natural gas lines or integrated propane tanks. Requires leak-free connections and proper pressure regulation.
• Battery and Start System: Keeps the generator ready to activate immediately. Needs regular load testing and maintenance.
• Cooling and Exhaust Systems: Maintain safe operating temperatures and direct engine emissions away from the home.
• Load Management Controls: Distribute generator output to priority systems like HVAC, refrigeration, or medical devices, especially useful for limited-capacity models.
• Remote Monitoring and Alerts: Modern systems feature Wi-Fi-enabled apps or monitoring devices that allow users to check fuel levels, maintenance schedules, and receive fault alerts remotely.

Each element plays a vital role in seamless backup protection. At Evenflow Home & Commercial Services, we inspect and optimize every part of your system so you’re never caught off guard.

Don’t guess when it comes to power security. Let our team ensure your generator system is always ready to perform.

Generator Maintenance

When to Consider

Maintenance should be scheduled annually or biannually, especially before storm season. Also consider maintenance after extended run times, post-installation, or when your system displays service codes.

Why It’s Important

Preventive maintenance extends your generator’s life, enhances efficiency, and ensures it activates when needed. It helps detect problems early, avoiding costly breakdowns.

What’s Included

• Battery checks and fluid top-offs: We test battery charge and load capacity, inspect for corrosion, and refill engine oil, coolant, and fuel additives to manufacturer specifications.
• Filter and spark plug replacement: Old filters and worn spark plugs reduce efficiency. We replace them with high-quality replacements to ensure clean combustion and reduce engine wear.
• Load testing and controller inspection: Our team simulates real-world outages using load banks to confirm that the generator can handle your home’s demands while also reviewing software logs and updating firmware.
• General inspection and cleaning: We check and tighten wiring connections, clean air inlets, inspect exhaust systems for blockages, remove debris around the unit, and ensure all safety labels are intact.
