Average Cost of Generator Installation at Home Depot

Average Cost of Air-Cooled Generator Installation

Air-cooled generators, which draw cool air from the atmosphere and blow it around the generator’s components to keep the unit cool, are well-suited for installations at home.

This is because this kind of generator can be mobile or permanently mounted based on the generator you pick, giving you greater installation options.

If you’re planning to install it in your home, you’ll need an emergency model designed to remain fixed in place and not move around.

Air-cooled generators are generally the most cost-effective choice over installing a liquid-cooled system which might be better suited to an extremely large structure and commercial area.

For the majority of homeowners who are looking for backup generators, air-cooled units offer plenty of power during the event of a temporary outage.

Here’s how the cost of installing an air-cooled generator breaks down:

Installation: $3,000 – $6,500. This includes the skilled labor required to install a backup generator around your home.

Materials: $2,500 – $6,500. Installing an air-cooled generator properly requires various materials, including the generator itself.

Average Generator Installation Cost By Unit Size

What size generator is selected at home will play a crucial role in how the generator can function.

A too small generator could not provide enough power to keep big appliances such as refrigerators or washing machines operating, as well as the lights, heat, and air cooling.

A unit that is too large for your space isn’t a risk. However, you could be spending more than you’re required to.

Here’s how the average generator installation cost differs by the size of the unit you’re installing:

  • 7.5 kW/1 generators:$5,000 – $6,500
  • 10-14 kW generators:$6,000 – $8,500
  • 15-18 kW (1K-3K sq ft home) generators:$7,500 – $9,500
  • 20-24 kW (3K+ sq ft home) generators:$9,000 – $12,500

20-24 kW generators are the most sought-after choice for customers due to their sufficient power to power a wide range of devices and appliances.

When you choose one of them, you’ll have ample backup power, even in a house with a total area of over 3,000 square feet.

Smaller homes with fewer appliances or where larger amounts of electricity are required could benefit from a 20-24 kW generator.

Understanding Your Generator Requirements

The right power source for the home may seem like a challenge, especially for a new homeowner who’s never had one before.

Knowing what you want from a generator about the appliances you’ll have to utilize when the power goes out could help.

In general, apply a formula to help determine what kind of generator would be ideal for your residence.

In the beginning, you’ll have to identify the square footage of your house before multiplying that by 3 to calculate the appropriate power rating.

3,000 square foot home = 9 kW rated generator

Use this formula and the area of your home to determine the minimum generator you’ll need for the space you live in.

Then, you can use the table below to figure out the amount of power you’ll require to power your appliances.

Combine these two numbers to figure out the type of generator you’ll need to power your home.

Note: 22kW generator is the most popular size.

Additional Pricing Considerations

The size of the generator you select will impact the total cost you will pay for the unit and the installation. Many other elements also affect the cost of installing a standby generator.

Additional Factors That Can Impact Pricing

Here are a few things you might want to be conscious of when trying to estimate your backup generator’s cost:

The preparation of the installation space: 

Hard-to-reach spaces or spaces that require landscaping might also have extra costs when installing.

Most of the time, the costs aren’t important, and most service providers are willing to take care of tasks such as removing furniture from outdoor spaces in the course of their work without charge.


Based on your location, you could require a permit from your local city for an automatic generator at your home.

Consult your municipal offices to find out more about the charges. The installation company can assist you with permit costs and permits because they are more knowledgeable about the procedure.

Your chosen location and general accessibility for installation: 

Where you choose to place your generator will depend on many variables. The general rule is that installation will be slightly more costly the farther away from your source of fuel and the circuit panel you select to place it.

Many homeowners find that balancing between hearing the generator, making it invisible, and having it installed at a lower cost is crucial.

Your job requires a separate fuel tank installation or a new connection to existing lines: 

There are additional expenses for upgrading an LP tank or purchasing a new NG meter, should you require it. Although these costs are usually small in comparison to the total cost, however, they could impact the total cost of installing a natural gas generator. 

The brand of generator you choose:

 Briggs & Stratton, Kohler and Generac are among our most well-known brands. With so many options in your reach, It’s worthwhile to compare top brands to find the one best suited to your home.

Are you unsure of which one to pick? Our expert team members can assist you in understanding the basics of Briggs & Stratton, Kohler and Generac standby generator installation costs in your residence.

What are the Future Considerations When Installing a Standby Generator?

Standby generators can offer security from power failures for many years to come. You may not have to utilize your generator for a long time after it’s set up.

Although a generator is sure to give you security in every situation, there are a few things you’ll need to consider.

The average lifespan of a standby generator: 

The standby generators can last for 10 years when they are regularly used. You’ll have to be in good shape with routine maintenance to ensure that your generator is in top condition.

Maintenance fees: 

On average, maintaining an engine costs between $100-$350 per year. Homeowners can perform certain maintenance tasks. However, professionals usually recommend routine inspections, especially before the cold and hot seasons.
