What’s Included

Generator Installation

As part of our whole-home energy and roofing services, we handle everything: sizing your system, coordinating the fuel line, wiring the transfer switch, and pulling permits for inspection. One team, one warranty, and a generator that’s ready when Texas weather isn’t.

Every installation starts with a full picture of your home’s electrical setup, not just a generator drop-off. Our licensed technicians handle:

  • Load calculation — reviewing your electrical panel and breaker box to determine how much power your home actually needs
  • Generator sizing — right-sizing the unit for whole-home coverage or essential-circuit backup
  • Fuel line coordination — connecting to natural gas or setting up a propane supply
  • Transfer switch installation — so your home switches to generator power automatically, with no manual hookup
  • Concrete pad placement — a proper outdoor foundation for the unit
  • Permits and inspection — we handle the paperwork so the system is fully code-compliant
  • Certified installation — trained on Generac, Kohler, and other leading generator brands

Whole-Home vs. Standby Generators

Not every home needs the same setup, and this is usually the first decision homeowners get stuck on.

A whole-home generator is sized to carry your entire house — HVAC, appliances, lighting, everything — through an extended outage without you having to prioritize what stays on. A smaller standby generator installation covers essential circuits only: refrigerator, sump pump, medical equipment, and a few rooms of lighting and outlets.

The right fit comes down to your home’s size, your must-keep-running appliances, and your budget. During your consultation, we run the load calculation and walk you through both options in plain terms — no oversized system you’re paying for and never using, and no undersized system that leaves you short when it matters.

Common Questions

Frequently Asked Questions

Talk to our team
How much power do I need for a whole-home generator?

It depends on your home’s square footage and which appliances you want to keep running. We calculate your home’s actual electrical load during the consultation rather than guessing off square footage alone.

What’s the difference between a portable generator and a standby generator installation?

A portable generator has to be manually connected during an outage and typically can’t run your whole home. A standby or whole-home generator installation is permanently wired to a transfer switch and starts automatically — no extension cords, no manual hookup.

Do I need a permit for backup generator installation?

Yes, in most Texas municipalities. We handle the permitting and schedule the inspection as part of the installation, so it’s already accounted for in your quote.

Will my generator run on natural gas or propane?

Both are common fuel options. If you already have a natural gas line, we can often tie into it directly; otherwise, we’ll help you plan for a propane tank sized to your generator.

How long does generator installation take?

Most residential installations are completed in 1–2 days once permits are approved, depending on the fuel line and electrical panel work required.
