Frequently Asked Questions

What size generator do I actually need for my house?

Most homeowners don’t need to guess—and shouldn’t. Generator sizing depends on your AC(s), electrical panel, and which loads you want backed up (refrigerator, lights, Wi-Fi, garage, medical devices, etc.).
We will come to your home, perform a load assessment, and design the right-sized system so you don’t overpay or end up underpowered.

Will it run my AC in a Houston summer outage?

In many homes, yes—if it’s sized and configured correctly. We plan around the reality of Houston: heat + humidity + long outage windows. During your assessment, we’ll confirm whether you can run one AC, multiple units, or use load management to keep comfort high without oversizing the generator.

Whole-home vs. ‘critical loads’—what’s better?

It depends on how you live. Whole-home is the smoothest experience—everything works like normal.

Critical loads focuses on essentials and can be more budget-friendly. We’ll walk your home and build a plan around your priorities—comfort, safety, and budget—not a one-size-fits-all package.

Natural gas or propane—what’s best in Houston?

If you have natural gas, it’s often a great option because it can run continuously during extended outages (fuel availability depends on infrastructure conditions). If you don’t have gas, propane can be an excellent solution with planned runtime. We’ll review your fuel availability, meter location, and property layout and recommend the cleanest, safest setup for your home.

Do I need permits in Houston / Harris County / Fort Bend / Montgomery?

In most cases, yes—especially for electrical and fuel connections. Permits protect you and your home’s resale value. We’ll guide you through what’s required in your area and handle the process as part of a proper installation.

How loud is it? Will my neighbors/HOA complain?

Modern standby generators are far quieter than portables, and placement makes a big difference. HOAs often have rules about location and visibility. We’ll help plan a layout that’s HOA-friendly and practical—then provide the information typically needed for approval.
