Power outages here aren’t rare. Spring and summer thunderstorms, straight-line winds and winter ice storms regularly take down lines across the Miami Valley and Greater Cincinnati — and when the remnants of Hurricane Ike crossed Ohio in 2008, many homes in the region were without power for days. A standby generator turns those outages into a non-event.
Unlike a portable generator, a standby unit is permanently installed outside your home, connected to your natural gas or propane supply, and wired through an automatic transfer switch. When utility power drops, it starts on its own within seconds and powers your home until the grid comes back — then shuts itself off.

Our generator installation process
1. Free on-site estimate & load calculation
We look at your electrical panel, your service size, what you want powered and where the generator can go. Then we size the unit with a load calculation so it isn’t too small to do the job or bigger (and pricier) than you need.
2. Whole-home or essential circuits
A whole-home setup powers everything, often using a service-rated transfer switch at the meter. An essential-circuits setup powers a selected subpanel — furnace, fridge, sump pump, lights, outlets and internet — with a smaller generator. We’ll explain the trade-offs in plain terms.
3. Placement, pad & fuel
Generators must meet manufacturer and code clearances from windows, doors, vents and structures. We plan a location that works for clearances, noise, appearance and the shortest practical runs for wiring and fuel. Natural gas units need an adequately sized gas supply; propane units need a properly sized tank — we’ll coordinate that piece with your gas provider or plumber as needed.
4. Permits, installation & inspection
We pull electrical permits where required, install the generator and transfer switch, and see the job through inspection.
5. Startup & walkthrough
We start the unit, test a simulated outage and show you how it works, how the exercise cycle runs and what maintenance to expect.
Does your panel need work first?
Older homes with fuse boxes, 60- or 100-amp services or full panels sometimes need an upgrade before a generator can be added safely. We can do both in one project — see electrical service & panel upgrades.

We install residential standby generators for homes along with automatic transfer switches, generator-ready subpanels and portable generator inlet and interlock kits.

Generator installation FAQ
How much does a whole-home generator installation cost?
It depends on the generator size, fuel type, transfer switch, the distance from your panel and gas meter, and whether your electrical service needs updates first. Every home is different, so we give you a firm price after a free on-site estimate.
What size generator do I need?
We size generators with a load calculation based on what you want to run during an outage. Some homeowners want everything — central air, electric range, well pump — while others only need essentials like the furnace, refrigerator, sump pump, lights and internet. We'll walk through both options.
Should I choose natural gas or propane?
If your home has natural gas service, it is usually the most convenient fuel because it never needs refilling. Homes without natural gas can run a standby generator on propane from an appropriately sized tank. We'll help you weigh the options during your estimate.
Do I need a permit to install a standby generator?
In most southwest Ohio communities, yes. Standby generator installs typically require permits and inspections, and gas piping may need its own. We handle the electrical permitting and inspection process where required and coordinate the gas side with your provider or plumber as needed.
How long does a generator installation take?
Timelines depend on permitting, equipment availability and any gas or panel work your home needs. We'll give you a realistic schedule along with your estimate.
Can I connect a portable generator to my house instead?
Yes, safely — with a code-compliant generator inlet and an interlock kit or transfer switch. Never backfeed a house through an outlet; it is dangerous to you and to utility line workers. We can install an inlet and interlock so you can run selected circuits from a portable generator.
Do standby generators need maintenance?
Yes. Like any engine, a standby generator needs periodic oil and filter changes, battery checks and regular exercise cycles to stay ready. Follow the manufacturer's schedule, and ask us about maintenance when you request your estimate.
