RV Generator Seasonal Maintenance

Why seasonal maintenance matters in Florida

RV generators in Jensen Beach face conditions that generators in Michigan or Arizona never deal with. The combination of heat, humidity, salt air, and dramatic seasonal usage patterns creates a unique set of maintenance challenges. Scott Marlins has been tackling these challenges for over 10 years across Martin County, and he's learned exactly what Florida generators need at different times of year.

Here's the reality: Jensen Beach sits at the intersection of two RV lifestyles. There are year-round residents who use their generators sporadically (mostly during power outages and camping trips), and there are snowbirds who arrive in October, use their RVs heavily through April, and then leave them sitting through the brutal Florida summer. Both patterns require different seasonal maintenance approaches, and Scott tailors his service to match how you actually use your RV.

Fall startup service (October through November)

This is the most popular seasonal service we offer. Whether you're a snowbird arriving for the season or a local getting ready for cooler-weather camping, fall is when your generator needs to be in peak condition. Here's what a fall startup service includes:

• Full oil and filter change (old oil from the summer sitting period gets removed)
• Air filter inspection and replacement if needed
• Spark plug check (replacement if the gap is out of spec or electrodes are worn)
• Fuel system flush if the generator sat with untreated fuel over summer
• Carburetor cleaning if varnish buildup is present
• Battery terminal cleaning and connection tightening
• Coolant level check on liquid-cooled generators
• 30-minute load test to verify output under real-world conditions
• Generator compartment cleaning (removing debris, insects, and rodent nests)

Fall startup service typically runs $225 to $375 depending on the generator model and how much attention the fuel system needs. If the RV sat all summer with treated fuel, the fuel system work is minimal. If it sat with untreated fuel, carburetor cleaning adds time and cost.

Spring storage preparation (April through May)

If you're heading north for the summer or just won't be using your generator much until fall, a spring storage prep service protects your investment during the hot, humid months ahead. This is about preventing damage during inactivity, which is when most generator problems actually develop. Storage prep includes:

• Fresh oil and filter change (clean oil protects internal surfaces during storage better than dirty oil)
• Fuel stabilizer treatment (added to fresh fuel and run through the entire system)
• Running the generator under load for 20 minutes to circulate stabilized fuel everywhere
• Corrosion inhibitor applied to exposed metal surfaces and electrical connections
• Air filter replacement (a clean filter prevents moisture-related mold growth in the intake)
• Battery disconnect or maintainer recommendation
• Exhaust outlet cover to prevent insects and moisture from entering
• Written log of hour meter reading and service performed

Storage prep typically runs $195 to $325. It's a smaller investment than the fall startup service because it's focused on protection rather than performance restoration.

Hurricane season preparation (May through June)

This one's unique to coastal Florida. When a hurricane or tropical storm knocks out power, your generator becomes your lifeline. It runs the refrigerator, keeps the AC going in 90-degree heat, powers medical equipment, and charges phones. You can't afford for it to not work when the grid goes down. Our hurricane prep service makes sure your generator is ready for exactly that scenario.

Beyond the standard seasonal service items, hurricane prep includes:

• Full load testing at maximum rated output (running AC, microwave, and other heavy loads simultaneously)
• Extended run test (1+ hour) to check for overheating under sustained load
• Fuel system service to ensure reliable starting after sitting
• Transfer switch inspection (if your RV has one)
• Recommendations for fuel storage and rotation during hurricane season
• Review of your generator's rated capacity versus your actual power needs

We've helped hundreds of Jensen Beach RV owners get through power outages after hurricanes and tropical storms. The ones who had their generators serviced beforehand fared much better than those who discovered their generator wouldn't start when they needed it most.

Mid-summer exercise service (July through August)

If your RV sits through the summer, the generator still needs attention. Even with proper storage prep, 4 to 5 months of sitting in Florida's heat takes a toll. We offer a mid-summer exercise service where Scott comes out, starts your generator, runs it under load for 30 minutes, checks all fluid levels, and inspects for any developing issues. This prevents the "it worked in April but won't start in October" problem that we see every fall.

The mid-summer exercise service runs $75 to $125 and takes about 45 minutes. It's cheap insurance against a much more expensive startup service in the fall.

Year-round maintenance schedule for Jensen Beach

Based on 10 years of experience working on generators in this specific climate, here's the annual schedule Scott recommends for RV generators in the Jensen Beach area:

• Every 2 to 4 weeks: Run the generator under load for 30 minutes (DIY)
• Every 100 to 150 hours (or annually): Oil and filter change
• Every 300 to 500 hours (or annually): Full tune-up with spark plugs, air filter, and load test
• October/November: Fall startup service if the generator sat over summer
• April/May: Storage prep service if the RV will sit over summer
• May/June: Hurricane readiness check
• July/August: Mid-summer exercise (if the RV is in storage)

Not every RV owner needs every service on this list. Scott will help you figure out the right schedule based on how you actually use your RV. The goal is to spend a few hundred dollars a year on maintenance instead of a few thousand on emergency repairs or generator replacement.

What 10 years of Florida generator work has taught us

Scott has completed over 3,200 repairs across Jensen Beach, Stuart, Palm City, and the rest of Martin County. The patterns are clear. Generators that get regular seasonal maintenance last 8,000 to 12,000 run hours. Generators that get ignored last 2,000 to 4,000 hours before major failures. The cost difference over a generator's lifetime is substantial: $300 to $500 per year in maintenance versus $3,000 to $7,000 for a premature replacement.

The most common seasonal issues we see are fuel system problems from sitting (September through October), overheating from sustained summer use (July through August), corrosion on electrical connections from salt air (year-round), and starting failures after hurricanes because the generator wasn't prepped. All of these are preventable with proper seasonal maintenance.
