When a winter storm rolls off the Strait of Juan de Fuca and knocks out power across Jefferson County, a standby generator is the difference between a warm, lit home and a cold, dark one. But that reliability doesn't come automatically. We've watched too many homeowners across the Olympic Peninsula flip the switch during an outage only to hear silence, usually because the unit hadn't been serviced in years. At Double D Electrical, we've been installing and maintaining generators throughout Kitsap, Jefferson, and Clallam Counties since 1998. As Generac-trained installers and certified dealers for Kohler and Briggs & Stratton, we know exactly how our damp, salt-air coastal climate affects these machines. Here's what every homeowner should understand about keeping a whole-home generator ready to run.
A standby generator should be professionally serviced at least once a year, with many manufacturers and technicians recommending twice-yearly attention for units that run frequently or sit in harsh coastal conditions. Annual service typically includes an oil and filter change, battery testing, and a full operational inspection. Skipping maintenance is the leading reason generators fail to start when a real outage hits.
When to call a professional: if your unit throws an error code, fails a self-test, hasn't been serviced in over a year, or you notice unusual noise, smoke, or fuel smell.
A standby generator is essentially a small, weather-exposed engine paired with sophisticated electrical controls. Both halves wear over time, and several factors drive the need for consistent professional attention, especially here on the Peninsula.
Generator oil degrades whether the unit runs constantly or barely at all. It's the single most common reason home generators need routine service. Homeowners rarely notice it directly, but a shop technician will see darkened, thinned, or gritty oil during a check. Oil breaks down because heat, combustion byproducts, and moisture contaminate it over months of weekly self-test cycles. Running an engine on degraded oil accelerates wear on bearings and cylinder walls, shortening the machine's life and risking a seizure at the worst possible moment. In our coastal climate, condensation inside the crankcase is a real concern, the temperature swings around Port Townsend and Sequim drive moisture into the oil even on units that rarely produce power. Fresh oil at every annual service is the cheapest insurance a generator owner can buy.
The battery is the number-one cause of generators failing to start. Homeowners often discover it only during an outage, when the unit clicks but won't crank. Standby generator batteries live outdoors and endure the same cold, wet winters our homes do. Cold weather reduces available cranking power, and lead-acid batteries naturally lose capacity after a few years. Because the generator only draws heavily on the battery during an actual start, a weak battery can hide for months behind successful self-tests that barely load it. A technician measures voltage under load and checks terminals for corrosion, common in salt-influenced air near Bremerton and Port Angeles. A battery that tests fine in July can fail in a January windstorm, which is exactly when you need it.
Fuel delivery problems quietly disable more generators than any mechanical fault. On propane and natural-gas units, homeowners may notice rough running or a unit that starts and then stalls. Regulators clog, lines develop leaks, and connections loosen with vibration over hundreds of self-test cycles. Any fuel smell around the unit is a safety concern that warrants an immediate professional visit. Because the Peninsula sees plenty of rural propane installations, we regularly find aging regulators and pressure issues that only surface under the full load of an actual outage, not during a light self-test. Verifying fuel pressure and inspecting every connection is a core part of professional service.
The transfer switch and control board are the brains that decide when your generator takes over. Homeowners may see error codes, a blinking status light, or a unit that runs but never picks up the household load. Vibration, heat cycling, and moisture loosen terminals and corrode contacts over time. A loose connection can cause arcing, overheating, or a failure to transfer power when the grid drops. Given our damp climate, moisture intrusion into control enclosures is a recurring find. Testing the automatic transfer sequence, simulating a real outage, is one of the most valuable things a technician does, because it confirms the whole system works together, not just the engine.
Salt air and near-constant humidity are hard on any outdoor equipment, and generators are no exception. Homeowners might spot surface rust on the enclosure or corrosion on hardware and terminals. Salt-laden moisture attacks metal connections, hastens battery-terminal corrosion, and can work its way into electrical components. Left unchecked, corrosion causes intermittent faults that are maddening to diagnose. Properties closer to the water, around Bainbridge Island, Poulsbo, and the Port Townsend waterfront, see this faster than inland homes. Regular inspection lets a technician catch corrosion early and protect connections before they fail.
You can safely check a few things between professional visits to catch problems early:
Safety reminder: Never open the generator enclosure, disconnect the battery, or work near fuel lines yourself. These systems involve high voltage, stored energy, and fuel under pressure. Diagnostics and repairs should always be handled by a licensed electrician.
Most standby generators are worth maintaining and repairing for many years. The decision usually comes down to age, run-hours, and the cost of the fix relative to the unit's value.

When it's a close call, an honest inspection tells the story, we'd rather keep a good machine running than sell you a new one you don't need.
Professional standby generator service is far less expensive than an emergency repair or a failed start during a storm. Costs vary with the size of the unit, its condition, and what the visit uncovers.

When you schedule standby generator maintenance with Double D Electrical, here's what a typical visit looks like:
Our technicians are background-checked, drug-tested, and work under Washington State Electrical Contractor License DOUBLDE982PD.
Port Townsend: the no-start battery. A waterfront homeowner called after their Generac unit clicked but wouldn't crank during a windstorm. Our technician found a corroded, weak battery, the terminals had degraded in the salt air. We replaced the battery, cleaned the connections, and confirmed a clean start and transfer. The home was back on generator power the same day, and a maintenance plan now keeps that battery on a replacement schedule.
Sequim: the stalling propane unit. A rural property owner's Kohler standby would start and then die within a minute. During diagnosis we traced the problem to an aging fuel regulator that couldn't hold pressure under load. After replacing the regulator and verifying fuel pressure, the generator ran steadily through a full test cycle.
Poulsbo: the transfer that never happened. A homeowner's Briggs & Stratton unit ran perfectly on self-test but never powered the house during an outage. We found a moisture-corroded terminal in the transfer switch. After cleaning, repairing, and re-testing the automatic sequence, the system correctly picked up the home's load on our simulated outage.
A standby generator should be professionally serviced at least once a year. Units that run frequently or sit in harsh coastal environments like the Olympic Peninsula often benefit from twice-yearly service. Annual maintenance covers oil, filters, battery testing, and a full operational check, the items most responsible for keeping the generator ready to start during an outage.
Plan on an annual professional inspection at minimum for a whole-house generator. An inspection verifies the engine, battery, fuel system, and transfer switch all function together. Many homeowners around Port Hadlock and Sequim schedule inspections ahead of fall storm season so any issues are corrected before the first major outage arrives.
Standby generator maintenance includes an oil and filter change, air-filter and spark-plug inspection, battery testing, fuel-system checks, electrical-connection tightening, and a transfer-switch load test. The technician also inspects the enclosure and wiring for corrosion. This combination confirms the generator will start automatically and carry your home's load when the grid goes down.
Yes, a rarely used standby generator still needs annual maintenance. Oil degrades and moisture contaminates the crankcase over time regardless of run-hours, and batteries lose capacity while sitting idle. In our damp coastal climate, condensation and corrosion affect units even if they've never carried a real outage. Regular service keeps an idle generator dependable.
Heavier usage increases how often a generator needs service. A unit that runs through many outages accumulates engine hours quickly and may require oil changes and wear-part replacement sooner than the annual baseline. Generators that rarely run still need yearly service, but high-run-hour units on the Peninsula often move to a twice-yearly schedule.
Watch for error codes, a failed self-test, unusual noise, smoke, fuel odor, or visible rust and corrosion. A generator that clicks but won't start usually signals a weak battery. If your unit hasn't been serviced in over a year, it's due regardless of symptoms. When in doubt, have a licensed electrician inspect it.
