On service calls across Arlington we see the same problems repeat: transfer switches wired by a previous owner without a permit, propane lines sized for a stove or fireplace but not a whole-house generator, and control boards corroded from units set too close to grade in low-lying yards near the Stillaguamish River. We size the fuel line, transfer switch, and pad placement correctly the first time, so the system actually starts during the windstorm outages Snohomish PUD customers see every winter.
Local knowledge
What's different about generator installation in Arlington
Every area we serve is different — in Arlington, these three factors matter most.
Snohomish PUD outages here often stretch longer during fall and winter windstorms because many Arlington feeders run through wooded, rural stretches where falling trees take out lines for hours; an automatic transfer switch keeps a home powered without waiting on crews.
A large share of Arlington properties, especially east of downtown and out toward Oso Rd, aren't on natural gas; we size propane tanks and regulators specifically for generator startup load, since the existing household propane line is usually too small on its own.
Homes near the Stillaguamish River floodplain need generators set on elevated, properly drained pads with sealed conduit runs, not a slab poured flush with grade, which is the setup we most often find failing on older installs in this area.

No surprises
How a Arlington generator installation visit works
1
Site Assessment & Load Calculation
We walk the property, check the electrical panel, and calculate the wattage needed to run the circuits you actually want covered during an outage.
2
Fuel Source & Pad Placement
We confirm whether the home runs on propane or natural gas, size the fuel line and tank accordingly, and pick a pad location clear of flood-prone low spots and required setbacks.
3
Permitting
We pull the Snohomish County electrical and gas permits required for a fixed standby generator install before any equipment goes in the ground.
4
Installation & Transfer Switch Wiring
Our electricians set the generator, run conduit, and wire the automatic transfer switch into the main panel so the system switches over without you touching a breaker.
5
Startup, Testing & Walkthrough
We run a full test cycle including a simulated outage, confirm proper voltage output, and walk you through the self-test schedule and basic maintenance before we leave.

Straight answers
Generator Installation in Arlington — FAQ
How long do power outages usually last in Arlington during storm season?
It depends on the feeder, but Snohomish PUD outages in the more rural sections of Arlington, especially near wooded corridors and the Stillaguamish valley, can run anywhere from a few hours to over a day when trees take down lines. A standby generator with an automatic transfer switch keeps the well pump, fridge, and heat running regardless of how long the crews take.
Do I need a permit to install a generator in Arlington?
Yes. A fixed standby generator install requires an electrical permit and, if you're adding or upsizing a propane line, a gas permit through Snohomish County. We handle both as part of the installation so the system is inspected and legal to operate.
My house isn't on natural gas. Can I still install a standby generator?
Yes, and it's common out here. Most rural Arlington properties run on propane, so we size a dedicated tank and regulator for the generator's startup draw rather than tapping the small line that feeds your stove or water heater, which is usually undersized for the job.
Why did my existing generator fail to start during the last outage?
On service calls in Arlington the most common causes are a corroded connection from a unit set too low to grade, a weak or untested battery, or a transfer switch that was never sized for the panel it's tied to. We check all three during install and again at every maintenance visit.
