How it works
How a whole house generator install works
Site visit and load calculation
A licensed electrician looks at your electrical panel, your gas meter or propane tank and where the unit can sit, and lists what you want running in an outage.
Sizing and quote
We size the generator and transfer switch to your loads, and add load management where it lets a smaller unit do the job.
Permit
We pull the electrical permit and any local zoning or setback approvals.
Pad and placement
The unit sits on a pad outside, with the clearance from windows, doors and vents that code and Generac require.
Fuel connection
We coordinate the natural gas or propane connection, including any gas meter upgrade your utility requires.
Transfer switch and wiring
We install the automatic transfer switch and connect it to your panel and the generator.
Inspection, startup and registration
After inspection we start the unit, test a transfer, set up Mobile Link monitoring on your phone and register your Generac warranty.
Timeline
How long it takes
Most home standby installs take one to two days on site. Permits, the gas utility and equipment availability set the overall schedule, and we track each step for you.

Fuel
Natural gas or propane?
Every Generac air-cooled home standby generator can run on natural gas or liquid propane (LP). Which one fits depends on what you have at the house.
| Natural gas | Propane (LP) | |
|---|---|---|
| Fuel supply | Piped from your gas utility, so it does not run out | Stored in a tank on site, so run time depends on tank size |
| Output | Slightly lower rated output on the same unit | Full rated output (see the lineup table above) |
| Best for | Homes with a gas meter large enough for the generator | Rural homes and farms without natural gas |
| What we check | Meter size and gas line capacity | Tank size and placement, and your propane supplier |

Why a standby generator
Backup power that takes care of itself, for as long as the outage lasts.
Starts on its own
When the grid goes down, the transfer switch starts your generator within seconds. You don't need to be home.
Runs for days
Connected to natural gas or a propane tank, it keeps going through long outages, not just a few hours.
Powers the whole home
Furnace, AC, well pump, sump pump, fridge and freezer, all at once with the right size unit.
Protects your home
Keeps the heat and sump pump running, so a winter outage doesn't turn into frozen pipes or a flooded basement.
Built for Midwest weather
A weatherproof outdoor unit made for blizzards, ice storms and summer heat waves.
Tests itself
It runs a short self-test every week, and you can check its status from your phone.
Want backup that also lowers your power bill? Pair your generator with solar and a home battery. We install all three.

Generator questions
How much does a whole house generator cost?
Our 2026 ballpark installed prices run from about $13,500 for a 14 kW Generac to about $17,700 for a 26 kW unit, with 22 kW at about $16,600. Those prices include the automatic transfer switch. Prices may change without notice. See whole house generator cost.
What size generator do I need?
Most homes need 14 to 22 kW. A 22 kW unit is common for whole-home backup on a 2,000- to 3,000-square-foot home, while 10 to 14 kW covers essentials. We size yours with a load calculation. See our generator sizing guide.
Are you an authorized Generac dealer?
Yes. Wolf River Electric is an authorized Generac dealer. We install Generac home and commercial standby generators and register the warranty for you.
How long does installation take?
Most home standby installs take one to two days on site once the permit and fuel connection are scheduled.
Natural gas or propane: which is better?
Natural gas never runs out as long as the utility supply holds and your meter is big enough. Propane works anywhere and gives full rated output, but run time depends on your tank.
Will a generator run my whole house?
With the right size unit, yes: furnace, central air, well pump, sump pump and appliances. Load management lets a mid-size generator handle big loads one at a time.
How does the generator know the power is out?
The automatic transfer switch senses the outage, starts the generator and switches your home over within seconds. When utility power returns, it switches back and the generator shuts down.
Does it test itself?
Yes. It runs a short self-test on a schedule, and Mobile Link lets you check its status from your phone.
What warranty comes with it?
Generac's 5-year limited warranty on home standby generators. Ask us about Generac extended warranty coverage.
Can a generator work with solar and batteries?
Yes. We install all three and design the system so each one does its job. See battery vs generator.
