This is American Electrical Services, the electrical division of American Rooter & Drain — established in Caldwell, Idaho in 1945 and working the greater Treasure Valley ever since. For everyday electrical work beyond generators — panel troubleshooting, rewiring, new circuits — see our electrician services page. Idaho Electrical Contractor LIC# 3671445, electrical line (208) 782-8268. The estimate is free and done standing in your yard, because nobody can size one of these over the phone.
Nampa is not a new address for our trucks: 3,817 completed jobs at Nampa addresses, across 1,691 customers and 1,663 separate properties in the 83651, 83686 and 83687 zip codes. Those dispatch records begin in 2020, when the current system went in — the company is a great deal older than the database.
What size generator does a Nampa house actually need?
Not by square footage, whatever the big-box display implies. By starting loads, and by what you decide belongs on the list.
A motor pulls far more current in the instant it starts than once it is turning, and the generator has to swallow those instants without stumbling. Around here the ones that decide the size are the air conditioning compressor, a well pump if you have one, an electric range or dryer, and a heat pump or electric water heater. Counting them means an electrician at your open panel.
First, though, a decision only you can make, and it moves the price more than anything else:
- Everything, nothing rationed. The whole panel is backed up and the house behaves during an outage exactly as it does the rest of the year. Largest machine of the three, and on some houses it drags panel work with it.
- A named list. Furnace blower, refrigerator, well pump, sump pump, some lights and outlets, a medical device. Smaller unit, smaller pad.
- Everything, but taking turns. A load management module briefly drops a patient appliance — the dryer, the electric water heater — for the two minutes the air conditioner needs to start, then hands the power back. Nobody presses a button.
That third one is a sizing tool, not a gadget, and our packages include it for one appliance where needed, along with soft starts on the air conditioning compressors. Between them a Nampa house is often comfortable on a smaller engine than a blunt everything-at-once calculation would demand. Ask each bidder whether those items are inside their number, and ask which of a unit's two kilowatt ratings the quote was built on — a standby machine is rated once for propane and once for natural gas, and only half of that pair applies to your house.
Will my well and septic pump keep working when the power goes out?
This is where Nampa splits in half, and it is a question most Boise homeowners never have to ask.
Inside the city limits you are on Nampa city water. An outage is dark and irritating, but the taps still run. Move past the city edge — south toward Lake Lowell and the Deer Flat ground, west toward Greenleaf, south again toward Melba — and the house is on a private well. There an outage is no water at all: no taps, no toilets, no water for horses or cattle, because the pump is electric and nothing else is moving water up that casing. Add a septic system that pumps effluent uphill to a drain field instead of letting gravity do it, and that stops too. Day one is uncomfortable. Day two, on a well, the house is close to uninhabitable.
That is ground we already work. At Nampa addresses our records carry 18 well pump jobs, 32 septic jobs and 7 sump pump jobs — the plumbing side of this company has been down in a lot of Nampa well houses and drain fields.
A submersible starting under a full column of water is one of the heaviest starting loads on a property, so bring what you know to the estimate: roughly what horsepower the pump is (usually on a tag at the pressure tank or on the well log), whether it is a submersible down the casing or a jet pump in a pit house, how deep the well is, whether a second pump feeds a cistern or irrigation, and whether the septic is gravity or pumped — an effluent pump or grinder belongs on the backup list right next to the well.
The appliance people underestimate is the furnace, and it is useless without electricity, because a gas furnace still needs power for the blower, the igniter and the control board. A January outage here is a heating problem long before it is a lighting problem.
Do I need a permit, and who comes out to inspect it?
Yes — and the answer to who depends on which side of a line your house sits on. This is the most Nampa-specific thing on the page.
Inside the Nampa city limits, the City of Nampa handles it. The city's guidance is blunt: all electrical wiring installations, equipment changes, or any wiring installation require the installer to obtain an electrical permit from the building department before work starts. Development Services sits at 500 12th Ave S, and permits go through the city's online self-service portal. Work must be done by a state-licensed journeyman electrician employed by a state-licensed electrical contractor, with an exception for a homeowner working on a home they will live in for at least 180 days afterward. The city currently names the 2017 National Electrical Code as its adopted code, which matters because the code edition decides several details an inspector will look for.
Outside the city limits, in unincorporated Canyon County, it is not the city at all. Electrical, mechanical and plumbing permits and inspections out there go to the State of Idaho, through the Division of Occupational and Professional Licenses — different application, different inspector, different schedule.
Here is what surprises people every time: a Nampa mailing address does not mean you are inside the City of Nampa. The 83686 and 83687 zip codes reach well past the city boundary into county ground, and plenty of homeowners have lived at a Nampa address for a decade without needing to know which side of the line they are on. Buying a generator is when it starts to matter, and we settle it at the estimate rather than on install day.
A generator install is also usually two permits, not one — the electrical work, and the gas piping out to the machine. Both sit inside our installation packages: we file them and schedule the inspection. The inspector does not work for us, and that independence is the whole value of the step.
Can you dig across my yard if there is an irrigation ditch on it?
Sometimes not where you would like, and this catches more Nampa jobs than any other site condition.
Most canals, laterals and drains in and around Nampa belong to the Pioneer Irrigation District or the Nampa & Meridian Irrigation District, and their easements are real property rights, not lines on an old map. Under Idaho Code 42-1209, no encroachment on district facilities is allowed without the district's written permission — that covers digging in the easement strip, and also parking on it, stacking material on it, and building over it. A generator install means trenching a gas line and an electrical run across your yard, so where that trench goes has to be answered before anybody buys a machine.
The reason this network threads through so many ordinary Nampa back lots is history that never went away. Deer Flat Reservoir — Lake Lowell — was impounded from 1909 under the Bureau of Reclamation's Boise Project, and the canals and laterals cut across Canyon County to carry that water are still exactly where they were put. Subdivisions grew over farm ground, and a lateral that once watered a beet field now runs behind a row of houses off Greenhurst or Amity with a fence built against it. The water infrastructure is older than the neighborhood, and it has seniority.
Before any trench opens we file a locate request with Digline, Idaho's 811 service — state rules require it at least two business days and no more than ten before excavation, and the member utilities then mark their own buried lines. The gap worth understanding: 811 gets the utilities' lines marked, not yours. The gas line somebody ran to the shop, the sprinkler mainline, the septic line and drain field, the low-voltage wire to the gate — none are member facilities and none will be marked. Those we find by asking you and digging carefully where the answer is uncertain.
Should I run it on natural gas or propane?
Natural gas if the main already reaches your house, propane if it does not. Around Nampa that is decided by your street rather than by you — Intermountain Gas serves natural gas across most of the built-up city, and the further out you go the more likely a tank in the yard becomes the answer.
Natural gas means no tank, no deliveries and no runtime ceiling, but one thing has to be settled first and it is not the generator. A standby generator is a large gas appliance, and your meter was sized for a furnace, a water heater and a range — not those plus an engine running flat out. Whether the meter and service can feed the unit is part of our on-site assessment, and if they cannot, the upgrade is performed by your gas provider on their calendar and sits outside every one of our packages. That dependency on somebody else's schedule is why we raise it at the estimate rather than on install day.
Propane is the answer on the rural ground west and south of town, and it adds one thing natural gas does not: runtime stops being unlimited and becomes a number of gallons. So the questions change — how big the tank is, who fills it, whether it is filled before the season or after the first outage, and where it can sit, given that tank and generator both carry their own clearance rules.
Will my existing panel handle a generator?
Often yes, sometimes no — and Nampa produces more of the second answer than the newer valley suburbs do.
Nampa started as an Oregon Short Line railroad stop in the 1880s, and the blocks near the old depot and the downtown core hold houses far older than the subdivisions off Greenhurst, Amity and Middleton Road. Older house, older service, and a small or obsolete panel becomes a constraint on the project long before the generator does.
What the electrician looks at when he opens the cover: service size, because a 100-amp and a 200-amp service are different projects once a transfer switch lands in the middle of them; where that switch goes, at the panel or out at the meter, since our packages include a 200-amp OEM automatic transfer switch with a 400-amp upgrade for larger services; free breaker spaces and the condition of the bus; grounding and bonding, because the generator becomes a second source of power for the house; and whether a heat pump, hot tub or EV charger is coming, since that belongs in the decision now rather than twice. If the panel is the real constraint, that is its own project with its own permit and price, covered on our panel upgrades page for Nampa, and we say so at the estimate rather than at the end.
One safety note belongs here. If your outage plan today is a double-ended cord from a portable into a dryer outlet, replace it whether or not you buy a standby machine — it energizes your panel through a path with no switch in it and can push power back toward a lineman who was told the street is dead.
How long does the whole thing take from the first phone call?
The work runs in a fixed order and you get dates in writing before anything is ordered. What stretches the calendar is almost never the wiring — it is permitting, the gas provider if a meter has to change, and the equipment.
1. The estimate. A licensed electrician opens the panel, finds the gas meter, measures the run to where the machine can legally sit, walks the trench route for irrigation easements, and asks what you want still running. Fixed price in writing. Free.
2. Permits and locates. Electrical and gas piping, filed by us to the city or the state depending on which side of the limit you sit on, plus the Digline ticket with its notice window built into the schedule. If the gas meter has to change, that step belongs to your provider — paying us more does not move their date, which is why we find out at the estimate.
3. Pad and set day. A pad rated to 180 mph wind or a poured slab; on ground that floods, drifts or sits low, a custom aluminum stand fabricated and anchored on site to lift the machine clear of snow and standing water. Then the unit is placed, the gas line run and pressure tested, the electrical pulled, and the transfer switch landed.
4. Startup, then inspection. The machine is commissioned and the transfer is proved by actually taking the utility away from it, with the exercise schedule set while you are standing there so you know what a normal cycle sounds like. Then somebody who does not work for us signs it off.
After that the machine wants oil, plugs, an air filter and a watched battery on a schedule set by run hours and calendar time — the battery hardest, because terminals oxidize outdoors and the charger that tops them up can fail quietly, and neither announces itself until the night you need the machine.
What does a whole home generator cost here?
The machine is one line on the invoice and your property is the rest of it, which is why we do not publish generator prices and will not quote a range. A range does nothing except set you up to be disappointed by the real number. Our reasoning is at why we won't quote a price over the phone.
What actually moves the figure on a Nampa lot:
- How far the machine sits from the gas meter and the panel. Our packages assume a short run with gas and electrical on the same side of the house. Once either run passes 30 feet, or the two land on opposite sides, the job steps up a tier; past 50 feet it steps up again.
- Trenching, and what it crosses. Turf, gravel, a driveway, tree roots, a sprinkler mainline — and whether an irrigation easement forces a longer route than the straight line you pictured.
- What it sits on, and where. A wind-rated pad, a poured slab or a fabricated stand, plus clearances from windows, doors, the property line and a propane tank all competing for the same corner of the yard.
- Add-ons. Surge protection, load management beyond one appliance, a 400-amp transfer switch.
Two things sit outside our price entirely and you should hear about both before signing: a gas meter upgrade if your provider has to perform one, and panel work if the panel turns out to be the constraint.
Do you come out to my part of Nampa, and how soon?
All of it — 83651 through downtown and the older core, 83686 south toward Lake Lowell and the Deer Flat ground, 83687 north and east toward the interstate and the Garrity corridor, and the county addresses in between that carry a Nampa name without sitting inside the city limits.
We are next door in every direction too, which matters when one storm takes a wide area out at once: Caldwell, Middleton, Kuna and Meridian each have their own page, and the full picture of a standby system is on the whole house generator installation page. While we are out the same visit can cover a panel upgrade, an EV charger or an electrical repair in Nampa; if the well or septic is part of what you are protecting, the plumbing side handles well pump repair and septic work in Nampa under the same roof; and every trade we run at a Nampa address is on our Nampa page.
Call (208) 782-8268 and ask for the next estimate opening. There are 26 electrical estimate visits at Nampa addresses already in our records — the visit is free, it is a licensed electrician rather than a salesman, and you finish it knowing which permitting authority you fall under and what your house needs to stay awake next time the valley goes dark.
