Why Invest in Generator Installation?

Keep Critical Appliances Running

Generators keep essential systems like refrigerators, sump pumps, furnaces, and medical devices operating even during extended outages.

Protect Your Family and Property

Avoid hazards like frozen pipes, spoiled food, or failed security systems. Reliable backup power keeps your home safe and functional.

Automatic Convenience

With a standby generator and ATS, your system turns on and off without you lifting a finger. It’s always ready, day or night.

Prevent Costly Damage

Outages can lead to water damage, freezing, or expensive equipment failures. A properly maintained generator helps you avoid those headaches.

Boost Home Value

Buyers appreciate the added security of a backup power system. A professionally installed generator can increase your home’s value and appeal.

Choosing the Right Generator for Your Home

Not all generators are created equal, and not every home needs the same kind of backup power. At Landmark Electric, we help you choose the right generator based on your home’s size, your daily needs, and your budget. Whether you want whole-home coverage or just enough power for essentials, we’ll guide you through every option.

Standby Generators vs. Portable Generators

Standby Generators (Whole-Home Backup)

These are permanently installed outside your home and turn on automatically when the power goes out.

  • Best for: Homeowners who want uninterrupted power
  • Can power: Entire home or specific high-demand appliances
  • Fuel: Natural gas or propane
  • Features: Automatic transfer switch, self-testing, low maintenance

Portable Generators

These generators are movable and manually connected when needed. They typically power only a few circuits or devices.

  • Best for: Budget-conscious backup power
  • Can power: lights, fridge, sump pump, and a few outlets
  • Fuel: Gasoline (some models propane)
  • Features: Requires a transfer switch or interlock kit for safe connection

What Size Generator Do You Need?

The right size depends on what you want to keep running during an outage. We help you determine your home's total wattage needs by evaluating:

  • Appliances (refrigerators, sump pumps, HVAC, ovens)
  • Electronics (TVs, computers, routers)
  • Lighting and outlets
  • Medical equipment, if applicable


Too small, and you’ll overload the unit. Too big, and you’ll waste fuel and money. We make sure your generator is the right one for your home.

Don’t get caught unprepared. Contact us today and let our professionals install your generator hookup safely and efficiently.
