by | Feb 17, 2025 | Electrical, Generator

Power outages are becoming more common across the U.S., and Ohio is one of the hardest-hit states due to severe storms. As a result, more homeowners are looking for ways to stay prepared. A whole-house generator provides reliable backup power, keeping your home running year-round. If you’re considering one in 2025, understanding the cost is key to planning your budget.

With that in mind, let’s review the costs and see why expert installation is worth it.

Why More Homeowners Are Buying Generators

Power outages are no longer rare; they have become a regular problem for homeowners. Strong storms, old power grids, and changing weather have made blackouts more common, sometimes lasting for days.

For homeowners in Greater Dayton, Greater Columbus, and Greater Cincinnati, where storms and ice buildup can easily cut off power, having a whole house generator is a must. You may not realize how important a generator can be until you go through a long power outage.

Main Benefits of a Whole House Generator

Here are some of the best reasons why investing in a generator is a good idea:

  • Comfort at All Times – Keeps your heating, cooling, and important appliances working.
  • Peace of Mind – Keeps your family safe, especially if someone needs power for medical devices.
  • No Work or School Interruptions – Keeps remote work and online learning running smoothly.
  • Winter Protection – Stops your home from getting dangerously cold during freezing temperatures.

What Affects the Whole House Generator Cost?

The whole house generator cost depends on several things, including size, fuel type, installation, and extra features. Here’s what you need to know:

1. Generator Size

The size of your generator decides how much of your home it can power. Here’s a simple guide:

  • 7-10 kW – Best for small homes and a few key appliances.
  • 12-20 kW – Great for mid-sized homes with multiple appliances.
  • 20-48 kW – Can run large homes or provide full backup power.

2. Fuel Type

The fuel you choose will change both the initial price and long-term costs. Here are the most common choices:

  • Natural Gas – Budget-friendly and needs less upkeep.
  • Propane – Flexible but may have higher fuel costs.
  • Diesel – Lasts longer but costs more upfront.

3. Installation Costs

Getting a generator installed by a professional is necessary for safety and proper function. Also, factors like your home’s electrical system, the generator’s location, and fuel setup affect pricing. In most cases, installation alone can raise the whole house generator cost to $12,000–$14,000.

4. New Generator Features

Newer generators come with smart features that make them easier to use and more efficient. Some of the most popular ones include:

  • Automatic Transfer Switches – Switches to backup power as soon as the main power goes out.
  • Wi-Fi Monitoring – Lets you track generator performance remotely.
  • Noise Reduction – Runs more quietly to reduce disruption.

How Much Will a Whole House Generator Cost in 2025?

Looking at current market trends, the whole house generator cost in 2025 will likely be:

  • Average Price Range – $12,000 to $14,000 (including installation)

While this gives a general idea, the final cost will depend on the factors mentioned above.
