Generator Maintenance FAQs
How often should a standby generator be serviced?
Standby generators typically require annual maintenance, though homes that experience frequent outages or have high-demand systems may benefit from semi-annual service. Manufacturers like Briggs & Stratton and Generac recommend yearly tune-ups to protect engine components, maintain voltage stability, and ensure the generator is ready when an outage occurs.
What is included in a generator maintenance service?
A full tune-up includes oil changes, filter replacement, spark plug inspection, coolant checks, battery testing, airflow inspection, electrical output testing, startup tests, and ATS operation review. Our technicians perform a multi-point inspection to ensure every component is functioning safely and efficiently.
Why is generator maintenance important?
Without regular service, generators can experience battery failure, clogged filters, worn components, voltage issues, or startup failures during a real outage. Maintenance extends equipment life, prevents costly repairs, improves performance, and ensures your home stays protected year-round.
Do you provide maintenance for all generator brands?
Yes. While we are a Certified Briggs & Stratton Dealer, we service all major brands, including Generac, Kohler, Champion, Honeywell, Eaton, and others. Our licensed HVAC and electrical specialists are trained to perform maintenance on all models and fuel types.
Can maintenance prevent generator failure during a storm?
Absolutely. Most generator failures during storms are caused by issues that proper maintenance would have identified—such as weak batteries, old oil, clogged filters, or faulty sensors. Regular service gives your generator the best chance of performing flawlessly during extreme weather.
How long does a generator tune-up take?
Most tune-ups take between 60 and 90 minutes, depending on generator size and condition. If additional repairs are needed, we provide clear recommendations and options before performing any additional work.
What are signs my generator needs immediate service?
Signs include slow startup, unusual noise, error codes, low voltage output, fluid leaks, excessive vibration, fuel odor, or failure to run a full cycle. If your generator behaves differently than usual, schedule service as soon as possible.
Do you test the automatic transfer switch during maintenance?
Yes. We test ATS switching, communication, relay operation, voltage sensing, and safety controls. A generator depends on a properly functioning ATS, so verifying its operation is a critical part of maintenance.
What happens if my generator hasn’t been serviced in years?
We can bring it back to proper operating condition through restoration service: replacing oil and filters, clearing blockages, testing electrical output, verifying safety systems, and correcting wear-related issues. Neglected generators often require extra attention, but they can usually be restored safely.
Do you offer annual or seasonal maintenance plans?
Yes. Our yearly and bi-yearly plans include priority scheduling, reminders, discounted service bundles, and complete inspections tailored to your generator’s requirements. A maintenance plan is the easiest way to ensure your generator stays reliable long-term.
