A whole home standby generator does exactly what the name suggests: it powers your entire home when the utility power goes out. Unlike portable generators that run a few circuits, or partial-home systems that force you to choose what stays on, a whole home generator keeps everything running—automatically.

What Is a Whole Home Generator?

A whole home standby generator is permanently installed outside your house and connected to your electrical panel through an automatic transfer switch. When utility power fails:

  1. The transfer switch detects the outage within seconds
  2. The generator starts automatically
  3. Power transfers from utility to generator
  4. Your entire home has electricity—typically within 10-30 seconds

When utility power returns, the process reverses. The transfer switch moves your home back to grid power, and the generator shuts down and returns to standby mode. You don't have to do anything.

Whole Home vs. Partial Home Coverage

Some homeowners opt for smaller generators that only power essential circuits—refrigerator, sump pump, a few lights. While this costs less upfront, it comes with trade-offs:

Partial Coverage Limitations

  • No air conditioning or heating
  • Limited outlets—you're running extension cords
  • No electric cooking or hot water
  • Can't run multiple major appliances
  • Still feels like a power outage

Whole Home Advantages

  • Life continues normally during outages
  • Full HVAC operation
  • All outlets and appliances work
  • Home office stays fully functional
  • No decisions about what to power
  • Better for resale value

For Northwest Indiana homeowners who work from home or have families depending on reliable power, whole home coverage usually makes the most sense.

Sizing a Whole Home Generator

"Whole home" doesn't mean one-size-fits-all. Generator sizing depends on your home's electrical load:

  • Smaller homes (under 2,500 sq ft)

    —typically 16-20kW
  • Medium homes (2,500-4,000 sq ft)

    —typically 20-24kW
  • Larger homes (4,000+ sq ft)

    —typically 24kW or larger

But square footage is just a starting point. We calculate actual load based on:

  • HVAC system size and type
  • Electric vs. gas appliances
  • Well pump requirements
  • Hot tub or pool equipment
  • EV charger (if present)
  • Workshop or specialty equipment

We'd rather install a slightly larger generator than have you discover during an outage that you're overloading the system.

Fuel Options

Natural Gas

Most whole home generators in our area run on natural gas. If you have a gas line to your home, this is typically the best choice—unlimited fuel supply, no tanks to refill, and lower fuel costs.

Propane (LP)

For homes without natural gas service, propane is the alternative. You'll need a dedicated propane tank sized for your generator's consumption. We can coordinate tank installation with local propane suppliers.

What to Expect: Installation

Whole home generator installation typically takes 1-2 days once equipment arrives:

  • Day 1: Concrete pad, generator placement, gas line connection
  • Day 2: Transfer switch installation, electrical connections, testing

We handle all permits and inspections. From initial consultation to operational generator typically takes 2-3 weeks, depending on permit timing and equipment availability.

Investment and Value

Whole home generators represent a significant investment—typically $12,000-$18,000 installed, depending on size and site conditions. But consider what you're protecting:

  • Freezer full of food
  • Finished basement (sump pump failure = flooding)
  • Pipes (frozen pipes = major damage)
  • Work income (if you work from home)
  • Comfort and safety for your family

A whole home generator also adds to your property value—something potential buyers recognize and appreciate.
