What to Expect During the Installation of a Whole-Home Generator

Power outages can disrupt everything—comfort, security, even your livelihood if you work from home. That’s why more Dallas, TX homeowners are investing in whole-home generators. These systems offer seamless, automatic backup power for your entire home when the grid goes down.

If you’re considering installing a whole-home generator, it’s natural to wonder what the process involves. The good news? With a qualified team from Generator Authority and proper planning, the installation is straightforward, efficient, and causes minimal disruption to your home life.

Here’s what you can expect every step of the way—from initial consultation to final testing.

Step 1: In-Home Consultation and Power Assessment

The whole-home generator installation process begins with a professional in-home consultation. During this visit, one of our licensed technicians will assess your home’s specific power needs. They’ll ask questions like: What appliances do you want to power during an outage? Are you looking to cover the essentials—like the refrigerator, HVAC system, sump pump, and lights—or do you want to back up the entire home?

They’ll also examine your Dallas, home’s electrical panel, service size, and any high-draw equipment such as well pumps or electric water heaters. This information helps determine the right generator size for your home.

Choosing the proper capacity is crucial—too small, and it won’t power everything you need; too large, and you’ll pay more than necessary.

Step 2: Site Selection for the Generator

Next comes choosing a location for the generator itself. Whole-home generators are typically installed outdoors, similar to an air conditioning unit. Your installation team will help identify the ideal location—usually near the electrical panel and gas line. The site must meet code requirements for clearances and ventilation while being easily accessible for service and maintenance.

Things like landscaping, property lines, and HOA rules (if applicable) are also taken into account. A concrete or composite pad is usually installed to serve as the generator’s base. If no pad exists, your team will pour one or set a pre-formed base during the install.

Step 3: Generator Permitting and Utility Coordination

Before installation begins, all required permits must be secured. This step is typically handled by your contractor or installation company. We’ll coordinate with local authorities to pull electrical, plumbing, or mechanical permits, depending on what’s needed in your jurisdiction.

If your generator is powered by natural gas or propane, we may also need to coordinate with your Dallas, utility provider or propane company. For natural gas connections, pressure and volume must be verified to ensure the generator will operate correctly. For propane, tank size and placement must be confirmed, especially for larger units.

While permitting might add a bit of time to the process, it’s a crucial step for safety, compliance, and warranty protection.

Step 4: Whole-Home Generator Installation Day

On installation day, you can expect our professional team to arrive early and begin work immediately. The process typically takes one to two days, depending on your setup. Your power may be off for a short time while final electrical connections are made, but in most cases, that disruption is minimal—often just a few hours.

Here’s what installation involves:

• Placing the generator and securing it to the pad.
• Running and connecting the gas or propane line.
• Installing the automatic transfer switch (ATS), which signals the generator to turn on during an outage.
• Wiring the generator to your home’s electrical panel.
• Testing the fuel and electrical connections.

Safety is always a priority. Our installation team follows strict protocols to ensure your generator is properly grounded, ventilated, and up to code.

Step 5: Final Generator Testing and System Start-Up

Once everything is connected, our team performs a full system test. We simulate a power outage to ensure the generator kicks on automatically and powers the circuits it’s supposed to.

During this testing phase, we’ll also:

• Verify fuel pressure and flow.
• Check voltage and frequency output.
• Ensure proper communication between the generator and ATS.
• Inspect for any leaks, loose connections, or abnormal performance.

Once the system passes all checks, it’s activated for regular use. Most modern whole-home generators also come with remote monitoring options so you can keep an eye on system status from your smartphone or computer.

Step 6: Homeowner Orientation on Their New Generator

Before our team leaves, we’ll walk you through the system and explain how it works. You’ll learn how to monitor your generator, perform self-tests, and what to do in the event of an issue. We’ll also go over basic maintenance recommendations and answer any questions you have.

You’ll be given manuals, warranty details, and contact information for future service or support. We also offer routine maintenance plans to keep your generator in top condition over time.
