Generator Service and Upkeep in Delaware
A generator spends most of its life waiting. It may sit idle through months of mild weather, then be expected to start on the first try when a summer thunderstorm or nor'easter cuts the power. Routine service closes that gap. HomeMax services standby and portable generators for homeowners in Dover, Smyrna, and surrounding communities, paying close attention to the components that commonly keep a generator from running when you need it.
Whether you have a permanently installed standby system or a portable unit stored in the shed, the goal is the same: a generator that starts, carries its load, and shuts down the way it should.
What a Generator Service Visit Covers
Service needs depend on the type of generator, how much it runs, and the manufacturer's maintenance schedule. A typical visit focuses on the parts that wear out, lose charge, or drift out of adjustment over time:
- Changing the engine oil and oil filter
- Checking the air filter and spark plugs
- Testing the battery and cleaning its terminals
- Inspecting wiring, fuel connections, and hoses for wear or corrosion
- Confirming the transfer switch moves your home to generator power and back
- Reviewing controller alerts and the exercise schedule
- Clearing leaves, nests, and plant growth from around the unit
Why an Idle Generator Can Fail When You Need It
Sitting unused is hard on a generator. Starting batteries weaken with age, and a tired battery is a common reason a generator will not start. Engine oil breaks down over time even when the engine runs very little, rubber seals and hoses can dry out, and moisture can corrode electrical connections. Mice and insects also like a quiet, sheltered enclosure, where they may chew wiring or block airflow.
Portable generators carry an added risk. Gasoline left in the tank and carburetor goes stale and can leave gummy deposits that make the engine hard to start or keep it from running at all. A standby unit's scheduled exercise run helps keep it ready, but it cannot replace an inspection by someone who knows what to look for.
Signs Your Generator Needs Attention
Between service visits, pay attention to how your generator looks, sounds, and behaves. If you ever smell gas near the unit, move away from it and call your gas utility or propane supplier from a safe place. Otherwise, contact HomeMax if you notice any of these signs rather than waiting for the next storm to test it:
- A warning light, fault code, or alert on the controller
- Exercise cycles that are skipped or sound different than usual
- Hard starting, rough running, or surging under load
- Oil or fuel stains on the pad or ground below
- Smoke, burning smells, or new rattling or knocking sounds
- Flickering lights or tripped breakers while on generator power
