What Size Generator Do I Need for My Home in East Texas?

MALL Energy Home • June 11, 2025

When it comes to protecting your home from unexpected power outages, one of the most common questions we hear is:

“What size generator do I actually need?”


It’s a great question—and the truth is, there’s no one-size-fits-all answer.


Whether you’re in Longview, Tyler, Marshall, Shreveport, or anywhere else across East Texas, the right standby generator for your home depends on three key factors:


  1. The size of your home

  2. Your energy usage


  3.  What you want to keep running during an outage

💡 It’s Not About Bigger—It’s About Right

You don’t necessarily need the biggest or most expensive generator.  You need the right one for your lifestyle.

 

Do you want to run your entire home, including central air, fridge, washer/dryer, and electric water heater? Or are you focused on keeping essentials powered, like the lights, A/C, medical devices, and freezer?


The answer will determine whether you need a 14kW, 20kW, or whole-home load management system.

🛠️ Proper Sizing Requires Professional Expertise

This isn’t guesswork. Getting it wrong can lead to:

  • Overloading your system

  • Undersized performance (not everything works when the power’s out)

  • Wasted money on capacity you don’t need

At MALL Energy Home, we do more than sell generators—we custom-fit them to your exact needs. Our experts perform detailed assessments of:

  • Your home’s square footage

  • Your breaker panel and load

  • Your energy priorities during an outage

  • Future needs (like home additions, electric vehicle chargers, etc.)

We’ve been in the business for over 10 years, and among our leadership and technicians, we have decades of combined experience serving East Texas homeowners.

🔌🔌 What Will Your Generator Power?

Generator sizing isn’t just about what you want to run—it also depends on the size of your home. A 20kW system may fully power a modest home but only cover the essentials in a larger one. That’s why proper sizing matters.


Here’s a quick look at what different generator sizes can typically handle:

Generator Size What It Can Power
10 - 14 kW Essentials: fridge, lights, sump pump, small A/C unit
15 - 20 kW Essentials + some luxuries: central A/C, water heater, washer
22 - 26 kW + Most or all of your home—often considered “whole-home” systems

📏 But remember: These are general guidelines. The square footage of your home, the number of high-demand appliances, and your specific backup power goals all affect the final recommendation.


Not sure where your home falls? That’s what we’re here for.
