Why Generac Guardian Is the Industry Standard in Home Backup Power

Generac invented the home standby generator category and holds the largest market share in North America for a reason: reliability, innovation, and an extensive dealer/service network. Their Guardian series air-cooled units run on your home's natural gas or liquid propane supply — meaning there's no portable fuel to run out of and no refueling trips during a multi-day outage.

Unlike portable generators, Generac standby units are permanently mounted on a concrete pad beside your home, connected to your main electrical panel through an automatic transfer switch (ATS). The ATS constantly monitors grid voltage and frequency. When it detects a power failure, it signals the generator to start — the entire sequence takes fewer than 10 seconds. When utility power returns, the ATS transfers the home back to grid power and shuts the generator down automatically.

What's Included in Our Installation

Automatic Transfer Switch (ATS)

Installing and configuring the 200A whole-home or load-management ATS that seamlessly transfers your home between grid and generator power.

Generac Mobile Link Setup

Configuring Wi-Fi or cellular monitoring so you receive real-time alerts, run remote tests, and track generator status from anywhere via the mobile app.

Concrete Pad Installation

Pouring or placing a properly sized and cured concrete pad to permanently mount your Generac unit to code requirements.

Permitting & Inspections

Pulling all required Sumner County electrical permits and scheduling the final inspection to ensure your installation is code-compliant and insurable.

Transfer Switch Installation

We install a properly sized automatic transfer switch that isolates your home from the utility grid during an outage, preventing dangerous back-feed to utility workers.

Permit & Inspection Handling

Generac installations require electrical and gas permits in Gallatin. We pull all required permits and coordinate the final city inspection on your behalf.

💡 Pro Tip: Keep the area around your Generac unit clear of debris, leaves, and snow. Generac air-cooled units require unrestricted airflow through their cooling fins to maintain safe operating temperatures during extended outages. Also, schedule your first oil change at 25 hours of run time to keep the warranty valid.

FAQ

Generac Generator Installation FAQs

How much does a Generac generator installation cost in Gallatin, TN?

The total installed cost of a Generac Guardian system in Gallatin typically ranges from $5,000–$12,000+ depending on the unit size, transfer switch type, distance from the panel to the installation site, and whether gas line work is required. We provide a detailed, itemized estimate before any work begins. Call (615) 845-8350 for a free site assessment and quote.

How far from my house does the Generac unit need to be installed?

Generac Guardian units must be installed at least 18 inches from the home's exterior walls and at least 60 inches from any window, door, or opening that could allow exhaust to enter the building. The unit must also maintain minimum clearances from gas meters and other structures per local code. We perform a full site assessment to identify the optimal installation location.

Do I need a permit to install a Generac generator in Tennessee?

Yes. A standby generator installation in Sumner County requires both an electrical permit and, if gas work is involved, a mechanical/gas permit. Both permits must be pulled and inspected before the system is commissioned. We handle all permit applications, inspections, and utility notifications as part of our standard installation service — you don't need to manage any of that paperwork.

How often does a Generac standby generator need maintenance?

Generac recommends an annual service including oil change, air filter replacement, spark plug inspection, and battery check. The unit also performs a self-test exercise run once a week (typically for 12 minutes). The first oil change is required at 25 hours of run time to maintain the factory warranty. We offer generator maintenance service to keep your unit in peak condition year-round.
