Why Choose a Generac Standby Generator?

When it comes to backup power, Generac is the #1 selling brand in America for a reason. Unlike portable generators that require you to drag them outside, fill them with gasoline, and run extension cords through windows, a whole-home standby unit is a permanent fixture that integrates directly into your electrical system.

Professional Installation Process

The Kallmeyer Installation Process: What to Expect

Installing a standby generator is a major home improvement project that involves electrical work, plumbing (for fuel lines), and site preparation. At Kallmeyer Services LLC, we handle the entire process to ensure a seamless experience for our Hermann neighbors.

Every home in Hermann is different. We begin by calculating your home's total electrical load to properly size your Generac generator (ranging from 7.5kW to 26kW) to ensure it handles your "starting loads" without breaking a sweat.

Our Installation Process

circle calculate

We calculate your home's total electrical load by examining all your appliances. Do you have a 5-ton A/C unit? An electric range? A well pump? We size your Generac to handle your specific needs and starting loads.
circle location_on

Hermann has specific local building codes regarding generator placement. It must be a certain distance from windows, doors, and property lines. We handle all permitting through the city or county to ensure full compliance.
circle foundation

We install a level, reinforced base for your generator. This prevents the unit from shifting during Missouri's freeze-thaw cycles, protecting the internal components and fuel connections.
circle electrical_services

The "brain" of the system is the Automatic Transfer Switch (ATS). We install this next to your main electrical panel. When the grid fails, the ATS safely disconnects your home from the utility line and connects it to the generator.
circle gas_meter

We coordinate the connection to your natural gas line or propane tank. Our team ensures the pressure is regulated correctly so your Generac starts reliably even in sub-zero Hermann winters.

Why Professional Installation Matters in Missouri

It is tempting to look for a "handyman" to hook up a generator, but professional installation by a licensed electrician is vital for several important reasons.

Warranty Protection

Generac requires professional installation to keep your multi-year warranty valid. Protect your investment with proper installation.

Safety

Improperly installed transfer switches can "back-feed" electricity into the utility lines, potentially injuring utility workers.

Code Compliance

We ensure all wiring meets the National Electrical Code (NEC), which is essential for your homeowner's insurance coverage.

Frequently Asked Questions: Generator Installation

We perform a "load calculation." We add up the wattage of everything you want to run simultaneously. For most Hermann homes, a 22kW or 26kW Generac Guardian unit provides full-home coverage, including central air.

It should be near your gas meter and electrical panel, but at least 5 feet away from windows, vents, or doors. We'll find the safest, most discreet spot on your property.

Yes. In the Midwest, a standby generator is a high-value asset. Real estate studies suggest it can increase home value by 3% to 5%, making it an investment that nearly pays for itself.

Modern Generac generators are designed with sound-attenuated enclosures. They are roughly as loud as a standard central air conditioning unit.

Yes. However, A/C units require a large "surge" of power to start. We often install a "Soft Start" kit or use Generac's load-shedding technology to manage this safely.

Yes! That is the primary benefit. If a storm hits while you're away, your pipes won't freeze and your basement sump pump will keep running.

As long as it has a fuel source (Natural Gas or Propane) and proper oil levels, a Generac can run for days or even over a week during major grid failures.

The generator requires a specific battery to start. We include a high-quality battery with every installation.

It is a device that senses when utility power is lost and automatically toggles your home's power source to the generator. It happens in about 10–20 seconds.

We program your unit to run a "weekly exercise" for about 5–12 minutes. This keeps the engine lubricated and the battery charged.

Both are excellent. Propane has a slightly higher energy density, while natural gas is more convenient since it never needs a refill. We can install for either.

We strongly advise against it. Between the gas plumbing, high-voltage electrical, and local permitting, it is a high-risk DIY project that could void your warranty.

Hermann winters can be brutal. We offer "Cold Weather Kits" (battery warmers and oil heaters) to ensure the engine cranks instantly in sub-zero temps.

The system is designed to "shed" non-essential loads or trip its own internal breaker to protect the engine from damage.

Simply call 573-680-1441. We'll come to your Hermann home, look at your panel and gas setup, and provide a detailed, transparent quote.
