Maintenance & Tune-Up
A generator that hasn't been serviced is a generator that will fail when you need it most. Double A keeps your standby generator ready for the next storm with thorough annual tune-ups and maintenance plans.
Our 8-Point Generator Preventative Maintenance
Every annual service covers all the critical systems that determine whether your generator starts and runs when the power goes out.
Oil & Filter Change
Fresh oil is the single most important maintenance item. We drain and replace the engine oil and install a new filter to protect internal components.
Spark Plug Inspection
We inspect and replace spark plugs as needed. Worn plugs cause hard starts, misfires, and reduced power output — especially under load.
Air Filter Replacement
A clogged air filter restricts airflow and causes the engine to run rich, reducing efficiency and increasing wear. We replace it on every annual service.
Battery Test & Service
The battery starts your generator when the power goes out. We test voltage, load capacity, and terminal condition — and replace it if it shows weakness.
Coolant Inspection
For liquid-cooled units, we inspect coolant level, concentration, and condition. Degraded coolant leads to overheating and engine damage.
Transfer Switch Test
We simulate a power outage to verify the automatic transfer switch activates correctly and the generator assumes the load within the required time window.
Full Load Test
We run the generator under load to verify it produces rated voltage and frequency, and that it handles your home's electrical demand without issue.
Visual Inspection & Report
We inspect the enclosure, fuel lines, exhaust, and electrical connections for wear, corrosion, or damage — and provide a written service report.

What Our Customers Are Saying
"Double A has been servicing our Generac for three years. They always call ahead, show up on time, and leave a detailed service report. When Hurricane Idalia hit, our generator started immediately and ran for two days without a hiccup. That's what proper maintenance looks like."
Carol S.
St. Johns, FL
"I neglected my generator for two years and it failed during a storm. Double A came out, diagnosed a dead battery and fouled spark plugs, and had it running the same day. Now I'm on their annual maintenance plan. Lesson learned."
David P.
Jacksonville, FL
"Signed up for the maintenance plan after Double A installed our generator. The annual service is thorough — they test everything and send a written report. Peace of mind knowing it'll work when we need it."

Generator Maintenance Questions
How often should a standby generator be serviced?
Generac recommends annual maintenance or every 200 hours of run time, whichever comes first. In Florida, where generators may run for extended periods during hurricane season, it's wise to schedule a post-storm inspection if your unit ran for more than 48 hours continuously.
What happens if I skip generator maintenance?
Skipping maintenance is the leading cause of generator failure during an actual outage. Stale oil degrades engine protection, weak batteries fail to start the unit, and dirty air filters cause overheating. A generator that hasn't been serviced may start fine during weekly self-tests but fail under the sustained load of a real outage.
Do you service all generator brands?
Double A specializes in Generac generators as an authorized dealer and service center. We also service Kohler, Briggs & Stratton, and other major standby generator brands. Call us at 844-432-8622 to confirm service availability for your specific unit.
How long does a generator preventative maintenance visit take?
A standard annual preventative maintenance visit typically takes 1–2 hours on-site. We bring all parts and supplies needed for a complete service. You don't need to be present for the entire service — just available to let us access the unit.
Do you offer generator maintenance plans?
Yes. Double A offers annual maintenance contracts that include priority scheduling, discounted repair labor, and pre-storm priority response. Ask about our maintenance plans when you call — 844-432-8622.
Do you service generators throughout Northeast Florida?
Yes. We service generators throughout St. Johns, Flagler, and Duval County — including Jacksonville, St. Augustine, Ponte Vedra, Palm Coast, and surrounding areas.
