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 21-Point Generator Preventative Maintenance
Every annual service covers all 21 critical inspection and service points required to uphold your manufacturer warranty and keep your generator ready for the next outage.
Oil & Filter Check / Change
We check oil level and condition and change as needed to protect internal engine components and maintain manufacturer warranty.
Oil Filter Replacement
Oil filter inspected and replaced as needed — a clogged filter starves the engine of clean oil and accelerates wear.
Valve Lash Clearance Adjustment
We check and adjust valve lash clearance to the manufacturer spec of .002–.004 in. to ensure proper combustion and prevent valve damage.
Enclosure Louver Inspection
Louvers are inspected for debris buildup that could restrict airflow and cause overheating or component failures during extended run time.
3-Foot Clearance Verification
We verify that 3 ft of clearance is maintained on two sides and the front of the unit as required by Generac and local code.
Water Intrusion Abatement Check
We inspect for sources of water intrusion — gutters, downspouts, grading — and flag any conditions that could damage the unit.
Fuel & Oil Line Inspection
All lines and connections are visually inspected for signs of fuel or oil leaks that could create a fire hazard or cause engine damage.
LP / Natural Gas Leak Test
We soap-bubble and leak-test all LP and natural gas connections to confirm a safe, code-compliant fuel supply to the unit.
Battery Condition & Charge Test
Battery condition, electrolyte level (if applicable), and charge level are tested. A weak battery is the #1 cause of no-start failures during an outage.
Oil & Filter Change at 200 Hours
If 200 hours of use have accumulated since the last oil and filter change, we perform the change regardless of calendar interval.
Air Filter Replacement at 400 Hours
Air filter replaced at 400 hours of use — or sooner if inspection shows restriction. A dirty filter causes rich running and overheating.
Spark Plug Replacement at 400 Hours
Spark plugs replaced at 400 hours of use — or sooner if worn. Fouled plugs cause hard starts, misfires, and reduced power output under load.
Sediment Trap Cleaning at 400 Hours
Sediment trap cleaned at 400 hours — or sooner if needed — to prevent fuel delivery issues that can cause the unit to run rough or shut down.
Additional Components & Options Test
All additional components or added options (cold weather kits, load shedding modules, remote monitoring) are tested for proper operation.
Component Lubrication
Moving components are lubricated as needed per manufacturer specifications to reduce friction and extend service life.
Software Upgrade
We upgrade the generator controller software to the latest Generac firmware to ensure optimal performance and access to the newest features.
Warranty Status & Pre-Emptive Filing
We uphold your warranty status and proactively file for any issues identified during the inspection before they become out-of-warranty failures.
Full Load Test with Outage Simulation
With customer permission, we simulate a power outage and run the generator under full load to verify it handles your home's electrical demand. (Optional — customer approval required.)
Connection Tightness Verification
All electrical and mechanical connections are checked and torqued to spec. Loose connections are a leading cause of transfer switch and control board failures.
Interior & Exterior Cleaning
We clean the inside and outside of the unit — removing debris, dirt, and corrosion — so the generator runs cooler and looks professional on your property.

Our technician provides written professional recommendations for anything observed during the visit and answers your questions — or connects you with the right person who can.

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. Our 21-point preventative maintenance covers oil and filter service, valve lash adjustment, battery test, LP/gas leak test, spark plug and air filter replacement (at 400 hours), software upgrade, full load test, and a complete written report. 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 904-867-7389 to confirm service availability for your specific unit.
How long does a generator preventative maintenance visit take?
A standard 21-point 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 and to discuss any recommendations at the end.
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 — 904-867-7389.
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.
