how much is a generac generator
A Generac generator can cost anywhere from around a few hundred dollars for a small portable unit to well over ten thousand dollars for a large whole‑home standby system, especially once you include installation.
How Much Is a Generac Generator? (Quick Scoop)
Fast price ranges
Here’s the big-picture breakdown of what people typically mean when they ask “how much is a Generac generator?”
- Portable Generac generators: roughly $500–$2,500 depending on wattage and features.
- Inverter-style Generac portables (quieter, more efficient): about $1,000–$3,000.
- Standby Generac generators (permanently installed, auto on/off):
- Smaller/mid-size units: about $2,000–$5,000 for the generator itself.
* Larger whole‑home units: **$10,000 or more** just for the unit.
- Popular residential standby sizes (around 10–26 kW) often list from about $3,500 up to $8,700+ for the equipment alone.
Many current guides say that “most homeowners” end up in the roughly $8,000–$15,000 range once you add professional installation to a properly sized unit , though very small or very large systems can fall outside that.
Generator vs “installed” cost
The number that surprises people is usually not the generator itself, but the total installed cost.
- A basic smaller standby setup can sometimes come in around $6,500–$7,000+ installed in typical examples.
- Common mid‑range whole‑home systems often land between about $8,000 and $15,000 installed , depending on size, local labor, gas line work, and permitting.
- Larger luxury or small‑commercial type systems can climb past $20,000+ installed , especially in higher‑cost regions.
One detailed pricing guide notes that a very popular ~22 kW Generac model often ends up around $8,200–$11,500 installed in many real‑world scenarios.
Typical sizes and what they cost
Below is a simplified snapshot of common home standby sizes and ballpark equipment prices (not including installation).
| Generator size (kW) | Typical home size/use | Approx. equipment price only |
|---|---|---|
| 10–14 kW | Smaller homes or “essential circuits” backup. | [1]~\$3,500–\$5,500 for the unit. | [1]
| 18–22 kW | Average‑size homes, near “whole‑home” backup in many cases. | [1]Roughly \$5,200–\$6,000+ for the unit. | [1]
| 24–26 kW | Larger houses, multiple AC units, heavier loads. | [1]About \$7,200–\$8,700+ for the generator. | [1]
| 30 kW and up | Very large homes, estates, or light commercial. | [1]Can reach from the mid‑teens to many tens of thousands of dollars. | [1]
Why the price can swing a lot
Several factors push the number up or down.
- Size (kW rating)
- Bigger kW = higher equipment cost and often more expensive installation.
* Oversizing “just in case” can add thousands you may not need.
- Type of generator
- Portable vs inverter vs standby: portable is cheapest, standby is the big investment but automatic and hands‑off.
- Region and labor costs
- Some regions show typical installation ranges from about $3,000–$10,000 , with coastal and high‑cost metros on the higher end.
- Gas and electrical work
- If your gas meter or line needs upgrading, or your electrical panel is old or full, those add‑ons can be a big chunk of the bill.
- Permits and local codes
- Some areas require more inspections, extra clearances, or sound/distance rules, all of which add time and materials.
Where to go from here
If you’re trying to decide whether a Generac is worth it, the usual advice is:
- List what you really want powered (full house vs essentials).
- Use an online sizing calculator or talk to a local installer to pick a realistic kW size.
- Get at least two local quotes itemized into: generator, transfer switch, gas work, electrical work, and permits, so you can see exactly what you’re paying for.
That way, when you ask “how much is a Generac generator?” you’ll get a number tailored to your home instead of a generic national range.
