By Loyal Lab Electric & Generators – Serving Somersworth, NH and Surrounding Communities

When a storm hits Somersworth, NH, and the power goes out, your generator becomes the unsung hero of your home. But here’s the truth: many homeowners don’t realize: a generator is only as reliable as the maintenance it receives.

At Loyal Lab Electric & Generators, we believe that peace of mind doesn’t come from just owning a generator—it comes from knowing it’s ready to run when you need it most.

The Problem: Generators Don’t Maintain Themselves

We’ve seen it too many times. A homeowner installs a generator, feels secure, and then… forgets about it. Fast forward to the next Nor’easter —and the generator won’t start. The oil’s old. The battery is dead. Or worse, a small issue that could’ve been prevented has turned into a costly repair.

You deserve better than that.

You invested in a generator to protect your home, your family, and your comfort. Let’s make sure it delivers when the moment comes.

Step 1: Run Your Generator Regularly

Just like a car sitting too long in the driveway, a generator needs regular exercise. If it’s a standby generator, it may already have a weekly self-test mode. If it’s portable, aim to run it for about 20–30 minutes once a month.

Why it matters:

  • Keeps fluids circulating
  • Prevents battery drain
  • Helps you detect problems early

Pro tip: Listen while it runs. Does it sound rough? Does it start slowly? These are early warning signs. Catch them now—avoid surprises later.

Step 2: Change the Oil and Filters

Generator engines work hard. Oil gets dirty. Air filters clog. Fuel filters degrade. Neglecting them can shorten the lifespan of your generator significantly.

General guidelines:

  • Oil: Change after the first 20–30 hours (brand-new unit), then every 100 hours or annually.
  • Air filter: Check every 50 hours, replace as needed.
  • Spark plugs: Inspect annually, replace every 100–200 hours.
  • Fuel filter: Replace every 200–250 hours.

Note: These are general rules—always refer to the manufacturer’s manual or talk to a pro at Loyal Lab Electric & Generators for specifics.

Step 3: Inspect the Battery

If your generator has a battery (most whole-home systems do), it’s a key part of the startup process.

Maintenance tips:

  • Check terminals for corrosion
  • Ensure tight, clean connections
  • Test voltage regularly
  • Replace every 2–3 years

A bad battery = no startup. And nobody wants to figure that out in a snowstorm.

Step 4: Keep It Clean and Covered

Your generator lives outside, especially in New Hampshire’s harsh weather. Snow, sleet, leaves, and dust can build up fast.

  • Clean the exterior regularly with a damp cloth (no pressure washers).
  • Clear snow and debris after storms.
  • Check for pest nests—mice love warm, dry spaces.

If you don’t have a weather-rated cover or housing, let us help. A protective enclosure can add years to your generator’s life.

Step 5: Monitor Fuel Supply

Generators can run on natural gas, propane, or diesel. Each has its own quirks:

  • Natural gas: Low-maintenance, but ensure your line is in good condition and pressure is consistent.
  • Propane: Check tank levels and valves. Top off before a major storm.
  • Diesel: Fuel degrades over time—use stabilizers and rotate supply.

Don’t wait until a storm warning to find out you’re low on fuel.

Step 6: Schedule Annual Professional Maintenance

Even with diligent self-care, nothing replaces a professional inspection. At Loyal Lab Electric & Generators, we offer affordable annual generator maintenance plans that cover everything from fluid checks to load testing.

Our comprehensive service includes:

  • Full inspection and diagnostics
  • Oil and filter changes
  • Battery testing and replacement (if needed)
  • Load simulation to ensure full power capability

This isn’t just a tune-up. It’s a stress test for your generator’s reliability.

Step 7: Keep a Log

It may sound simple, but keeping a maintenance log makes a huge difference. Record:

  • Run times
  • Oil changes
  • Filter replacements
  • Service appointments
  • Notable performance issues

This helps you track trends, comply with warranties, and catch problems early.
