Generac 25kW Protector Standby Generator
Twenty-five kilowatts, liquid-cooled.
The smallest Protector. A car-style engine that runs cooler, quieter, and longer than an air-cooled unit. For a big house that wants the better engine, or a common pick for small offices.
Financing through Synchrony and others. How that works →
Generac Prestige DealerGenerac's highest dealer designation. We sell, install and service Generac home standby generators.
Generac generators$2,000 off a generator install. While supplies last.
It only comes off the units on our floor, so when they're gone, it's gone. New air-cooled Generac installs come with a free 10-year warranty, and financing is there if you want it. Permit timing depends on your city or county. The install itself is usually one day.
What a 25kW runs. Two air conditioners, or an all-electric home.
Two AC units without load shedding, or one AC with electric heat, water heater, dryer and range. The step up for pool homes and 3,000-plus square feet.
- Two central AC units
- Electric range, dryer and water heater alongside the kitchen
- Pool pump and pool heater
- Every light and outlet, garage doors, gates
- EV charger on a managed circuit
These are typical loads for this size with gas appliances and Houston-size air conditioning. Your panel, your AC tonnage and what you want on during an outage decide it. Five taps on the calculator gets you a recommended size; the free sizing visit makes it exact.
For a big house, or a small office, that wants the better engine.
Same size as a big Guardian, different engine. Liquid-cooled means cooler, quieter, and built for long outages.
Or a small office, dental practice, or shop.
Every AC, the kitchen, the pool, the servers. Nothing turns off.
Senses the outage, starts itself, switches the house over. Hands it back when CenterPoint returns.
- Pick it if: the house is big and you want the quieter, longer-life engine, or it's a small business that can't close.
- Step up if: the load runs past 25. The 30 and 32 are next.
Not sure? Five taps on the calculator gets you a size, or call and we'll size it on the phone.
In plain English.
Generac's spec sheet has a lot of words on it. This is what they mean for you.
It turns itself on.
Power goes out, it senses it, starts, and switches everything over in about ten seconds. Power comes back, it hands it back. Nobody has to be there.
A car-style engine, built to run for days.
Liquid-cooled, like the engine in your truck. It runs cooler, quieter, and longer than an air-cooled unit, which is why this is what goes in when the load is big or the outage might be long.
Quieter than the size suggests.
A sound-attenuated enclosure and a slower-turning engine. Neighbors, patients, and diners notice less than you'd think.
It runs on natural gas or propane.
The gas line you already have, or a tank. No diesel deliveries, no fuel going stale.
Single-phase or three-phase.
We match the unit to the service your building already has. You don't need to know which. We look at the meter.
You can watch it from your phone.
Mobile Link app. Cellular built in with Wi-Fi backup. Status, run history, and service alerts from anywhere, and the servicing dealer can see faults early.
Wired installs, around Houston.
Real photos of our installs around Houston and Tomball: the unit set on its pad, the transfer switch and gas line run, and the startup test before we leave. The unit in a photo may be a different size than this one.

No price tag on the website. Here's why, and how to get your number.
The unit is only part of it. The gas run, the pad, the transfer switch, and your panel change the number from one house to the next, so a price on a web page would be wrong for most people. Getting the real one is quick.
