Generator Services in St. Louis

Home Standby Generator Installation, Repair, & Maintenance Serving St. Charles & St. Louis Counties 

Power outages in the St. Louis area are not a matter of if; they're a matter of when. Whether it's a severe thunderstorm rolling through St. Charles County, an ice storm knocking out lines in Franklin County, or an equipment failure on a sweltering August night, losing power means more than inconvenience. For households with medical equipment, young children, or freezers full of food, the stakes are real. 

A home standby generator removes that vulnerability, switching on automatically the moment the grid goes down and running until power is restored.

Potts Electric has been helping St. Louis homeowners take control of their power since 2021. Our licensed team handles the full scope of generator work, from sizing and installation to ongoing maintenance and repairs, and we back every job with a satisfaction guarantee.

How to Choose the Right Home Standby Generator for Your St. Louis-Area Home

Not all generators are created equal—and the “right” system depends on what you want to keep running during an outage. Potts Electric, LLC helps homeowners in Fenton and throughout Franklin, St. Charles, and St. Louis Counties select a standby generator that matches their home, budget, and comfort expectations without overpaying for unnecessary capacity.

Start With Your Power Priorities

Before we recommend a generator, we’ll walk through what matters most to you. Some homeowners want essentials only, while others prefer near whole-home coverage.

• Essential circuits: refrigerator/freezer, sump pump, furnace blower, well pump, key outlets, garage door, and select lights
• Comfort add-ons: Wi-Fi equipment, home office, microwave, and laundry
• Whole-home coverage: larger loads like central A/C, electric ranges, hot tubs, or pool equipment (when desired)

Why Proper Sizing Matters

A correctly sized standby generator starts reliably, handles surge loads safely, and runs efficiently. An undersized system may struggle when large appliances kick on; an oversized system can cost more upfront and may not operate as efficiently. Our team accounts for your home’s electrical demands and starting amps to help you choose a generator that performs when you need it most.

Fuel Options & What to Expect

Most standby generators in the Metro St. Louis area run on natural gas or propane. We’ll discuss what’s available at your property and help you understand runtime, refueling considerations, and long-term convenience so there are no surprises during an extended outage.

Automatic Transfer Switch: The Key to Seamless Backup Power

A standby generator isn’t just a generator—it’s an integrated backup power system. The automatic transfer switch (ATS) detects an outage and safely switches your home to generator power, then switches back when utility power is restored. This provides:

• Fast, automatic response—no manual setup in bad weather
• Safe operation that prevents dangerous backfeeding
• Cleaner integration for select-circuit or whole-home coverage

Permitting, Code Compliance, and Clean Installation

Generator projects involve electrical code requirements and, in many cases, permits and inspections. Potts Electric, LLC focuses on a clean, professional install that’s designed for reliability and compliance—so your system is ready when the power goes out.

Make Outages Less Stressful With Ongoing Maintenance

Like any engine-driven equipment, standby generators perform best with routine care. Regular maintenance helps reduce start-up failures, catch battery issues early, and ensure your generator is ready for storm season.

What St. Louis Homeowners Should Know About Standby Generators

A standby generator is a permanent fixture connected directly to your home's electrical panel and natural gas or propane supply. Unlike a portable generator, it requires no setup, no extension cords, and no manual starting. When utility power drops, an automatic transfer switch detects the outage and signals the unit to start, typically within seconds.

Proper sizing matters more than most homeowners realize. A generator that's too small won't power the circuits that matter most; one that's oversized costs more than necessary upfront and runs inefficiently. Proper sizing starts with a load calculation that accounts for your home's square footage, critical circuits, HVAC system, and any high-demand appliances. Our licensed team performs this assessment before recommending any unit, so you get a solution matched to your actual needs rather than a generic one.

Generator Safety for St. Louis Homeowners

A standby generator is one of the most valuable investments a homeowner can make for resilience and peace of mind, but it is also a piece of equipment that demands respect. 

• The most critical safety requirement for any home generator is proper transfer switch installation. A generator connected to a home's electrical system without a transfer switch can backfeed power onto utility lines, creating a life-threatening hazard for utility workers in your neighborhood. Every Potts Electric generator installation includes a properly installed transfer switch that isolates your home's system from the grid before the generator comes online.
• Placement matters as well. Generators produce carbon monoxide, and that exhaust has to go somewhere other than into your living space. Standby generators should be installed at a safe distance from the home, with clearance from windows, doors, and any openings that lead to interior spaces. This is not a detail to work out after the fact. Proper siting is part of the installation plan, and our team assesses it before any equipment is placed.
• Once installed, a generator requires regular maintenance, which you can perform when you actually need it. Fuel systems, oil levels, spark plugs, and battery connections all require periodic attention, and a generator that has not been exercised or serviced in years may not start reliably during an outage. 

Potts Electric offers maintenance services for existing generators throughout the St. Louis metro, because the best time to find out your generator has a problem is not the moment the power goes out.
