Generac 14kW Guardian Standby Generator

Fourteen kilowatts. The starter.

Keeps the fridge cold, the lights on, and one AC running when the block goes dark. The one most people start with when they want to stop worrying and don't have a huge house.

Generac generators
Storm-Ready install package

$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.

In a Houston home

What a 14kW runs. A smaller home, the important rooms on.

Everything in a smaller house except the big electric appliances all at once. One AC, the kitchen, the lights.

  • One central AC up to about 4 tons
  • Refrigerator, freezer, microwave
  • Lights, outlets, Wi-Fi, TV
  • Garage door, gas furnace blower, gas water heater
  • Well pump or pool pump, staged

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.

Is this the one?

For a smaller home that wants the important stuff on.

The 14 is the one for "I don't need everything, I need the fridge, the lights, and the AC in the bedroom."

Built for
Up to about 1,800 sq ft

One AC unit, gas water heater and range.

Keeps running
The essentials, comfortably

Fridge, freezer, lights, Wi-Fi, garage door, one AC, with room to spare.

When the power goes out
On in about 10 seconds

Senses the outage, starts itself, switches the house over. Hands it back when CenterPoint returns.

  • Pick it if: one AC unit, gas appliances, and you want the basics on without thinking about it.
  • Step up if: two AC units or you want the whole house. That's the 18 or the 22.

Not sure? Five taps on the calculator gets you a size, or call and we'll size it on the phone.

What you're getting

In plain English.

Generac's spec sheet has a lot of words on it. This is what they mean for you.

01

It turns itself on.

Power goes out, it senses it, starts, and switches the house over in about ten seconds. Power comes back, it hands the house back and shuts down. You don't touch anything.

02

It runs on the gas line you already have.

No refueling, no gas cans in the garage, no cords through a window. On propane, your supplier runs the tank to the generator and we do the rest.

03

It checks itself every week.

A few quiet minutes, once a week, so it's ready when it counts. Generac calls it Quiet-Test. You'll barely notice.

04

It texts your phone.

A cellular connection is built in, so it doesn't even need your home Wi-Fi to reach you. The Mobile Link app tells you when it ran, when it started during an outage, and when it needs service. We set it up at the walkthrough.

05

The case doesn't rust.

Aluminum, with a baked-on textured finish, rated for winds up to 150 mph. That matters more in Houston humidity and hurricane season than anywhere.

06

We match the switch to your panel.

The automatic transfer switch is the box that moves the house from CenterPoint to the generator and back. It's not in the generator box; we pick the right one for your panel at the free visit, and it's part of the install, not an extra.

What it costs

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.
