A whole-home standby generator starts itself in seconds — heat keeps running, the well keeps pumping, pipes don't freeze, and food doesn't spoil. We sell two brands at two price points — Generac and Champion — prep your site, and coordinate the licensed hookup from start to finish, anywhere from Helena to Bozeman to Missoula.
Call anytime — even after hours. Main line: (406) 521-0015. Miss us? Our Uzziah AI assistant answers and texts back within minutes, qualifies your job, and books your assessment — 24/7.
Winter storms, ice on the lines, and summer wind events can knock out power for hours — sometimes days. At −20°F, a house without heat becomes a pipe problem fast.
Your furnace or boiler keeps running, so the house stays warm and pipes stay thawed through the coldest nights.
On a well outside city water? No power means no water. A standby unit keeps the pump — and your toilets — working.
A freezer full of elk, beef, and a year's groceries is worth protecting. No more racing a thaw during a long outage.
Starlink, Wi-Fi, computers, and phones stay powered — important if you work from home or run a business from the house.
CPAPs, oxygen concentrators, powered beds, and chair lifts can't wait for the grid to come back. This keeps them running.
No dragging a portable out in a blizzard, no extension cords, no carbon-monoxide risk. It starts, runs a weekly self-test, and reports its status.
However your place is set up, there's a generator configuration for it — and if you searched “generator near me,” “backup generator,” “backup power for my house,” or “off grid home,” you're in the right place.
The classic home generator setup: an automatic standby unit wired to your panel through a transfer switch. The power drops, the backup generator starts in about 10 seconds, and your whole house — heat, well, fridge, lights, internet — runs like nothing happened. No cords, no gasoline cans, no being home to start it.
Montana properties run on outbuildings — shops, barns, well houses, guest houses, second homes. We set up secondary power two ways: one whole-property unit sized for house plus shop, or a dedicated generator for the outbuilding, so stock water, tools, and freezers stay protected even when the house is covered separately.
Living off the grid — or building an off grid home the power lines don't reach? A propane standby generator is the reliable backbone of off-grid home power: it auto-starts to recharge your battery bank and carry heavy loads like well pumps and heat when solar isn't keeping up, especially through Montana winters.
“What size generator do I need for my home?” is the question we hear most — so we built the tool for it. Tick what has to stay on during an outage. We'll estimate the running load and point you to the right class of unit — your free site visit confirms it before anything is ordered.
Typical running watts shown — startup surges are handled in the recommendation.
* Managed loads — a load-management module lets a smaller generator run big appliances one at a time instead of all at once.
Same job either way: we sell you the unit and transfer switch, set the pad, deliver and place it, and coordinate the licensed electrical and gas hookup. The difference is the brand on the box — and what it costs.
The premium pick — America's #1 home standby brand
The name most people ask for first. Purpose-built G-Force engines, an aluminum enclosure, built-in cellular monitoring, and the largest dealer and parts network in the country behind it.
The value pick — same whole-home coverage, lower price
Champion's aXis line does the same job for hundreds to over a thousand dollars less per unit. Its controller talks to the transfer switch over your home's existing wiring, which can trim install time — and it carries the longest warranty in the class.
Equipment prices include the automatic transfer switch shown. Site prep and the licensed hookup are quoted firm after your free assessment.
Model 100837 — for smaller homes, cabins, and “keep the critical stuff on” setups.
Model 201222 — powers the whole panel for most family homes, A/C included.
Champion's biggest air-cooled unit — for large homes and shop + home properties.
The current air-cooled line, at 406 Generators equipment prices. Prices are equipment-only — generator plus automatic transfer switch. Site prep and the licensed hookup are quoted firm after your free assessment.
The entry Generac — essentials coverage for smaller homes, cabins, and second homes.
Model 7323 — the Generac way into standby power for smaller homes and cabins.
The step up — more of the house on at once, for mid-size homes with bigger loads.
Model 7325 — the most-installed whole-home size in America, now in the NextGen line.
For larger homes that run close to everything at once — A/C, well, shop loads.
Model 7328 — for large homes, shops, and everything-at-once properties. A 28 kW — the most powerful air-cooled standby made — is also available.

Equipment prices above are 406 Generators equipment-only prices for the generator and transfer switch (Champion prices are current market prices checked November 3, 2026) — they don't include the pad, delivery and placement, permits, or the licensed electrical and gas hookup. Those are quoted as one firm, itemized total after your free site assessment, and your written quote confirms the final equipment price before you sign anything. No surprises added later.
The whole house generator cost question has two parts: the equipment, and the generator installation cost to hook it up. Here's the honest all-in picture before you ever request a quote.
For the most common Montana setup — a 14–22 kW air-cooled whole-home generator with a 200A automatic transfer switch.
Fully installed: generator + transfer switch, pad and placement, permits, licensed electrical hookup, and licensed gas work.
Equipment alone runs $3,749–$7,181 for the Champion and Generac units in the lineup above. This range is a planning guide, not a quote — your free site assessment produces one firm, itemized number for your exact property, and that's the number you sign on.
Get my firm installed priceEvery property is different. These are the factors that push a job toward the low or high end of the range:
Searching “generator installation near me” to compare installed prices? Ask every bidder for the same thing: one itemized total covering equipment, pad, permits, electrical, and gas. That's the only apples-to-apples number.
You deal with one local point of contact. Behind the scenes we schedule the pad, the licensed electrician, and the licensed gas fitter around each other — so the job flows instead of stalling between trades.
We walk your property, check your panel and fuel, pick the placement, and size the unit. You get one firm written quote.
406 GeneratorsWe set the level pad, deliver the generator, and place it to code clearances — ready for hookup day.
406 GeneratorsA licensed electrician installs the transfer switch and pulls the electrical permit. A licensed plumber / gas fitter runs the fuel line and pulls the gas permit.
Licensed work — licensed partnersInspection, first start, a simulated outage with you watching, warranty registration, and monitoring set up on your phone.
TogetherOne contract, one point of contact, one schedule — ours.
Montana requires licensed trades for electrical and gas work, and the permit holder has to do their own work — nobody can legally “sign off” on someone else's wiring. We built our process around that from day one, so your install is permitted, inspected, and insurable.
A standby generator is a 15–20 year appliance. Placement, clearances, fuel sizing, and a level pad decide whether it starts on the coldest night of the year — we don't shortcut any of it.
Generators that get serviced start when it counts. Plans cover both brands we sell — Generac and Champion. Pick a plan and we handle the schedule — you just get the “all good” text after each visit.
Buying the generator is step one. Keeping it ready for the next outage is the rest of the job — and it's ours, for both brands we sell.
Generator down or showing a fault? Call or text (406) 521-0015 — start with the brand, model, and what the controller is showing, and we'll take it from there.
A standby generator only matters on the one night it has to start. Generator maintenance plus monitoring is how you know it will.
