How Much Does It Cost to Hook Up a Whole-House Generator? A Pricing Breakdown

When storms strike or unexpected power outages occur, being prepared is essential. Without electricity, everyday appliances—from your refrigerator to your HVAC system—can become useless, turning inconvenience into crisis. That’s why more homeowners are turning to whole-house generators as a dependable solution.

Installing a generator ensures your home remains powered, comfortable, and secure, even during extended outages. At JP Electrical, our licensed experts provide professional generator installation, so your home is ready when the unexpected happens.

Why Invest in a Whole-House Generator?

While many homeowners are willing to invest in a high-quality generator, choosing a whole-house generator brings significant long-term benefits:

• Uninterrupted power during outages
• Protection for sensitive appliances and electronics
• Peace of mind that your security system stays online
• Potential increase in property value

However, buying the generator is just the first step. Proper installation is just as important to ensure your system functions reliably when you need it most.

How Much Does It Cost to Install a Whole-House Generator?

The total cost to hook up a whole-home generator can vary depending on several key factors, including the size of the unit, the complexity of the installation, and any additional work required. Below is a breakdown of typical expenses so you know what to expect.

1. Cost of the Generator Itself

The generator unit is the biggest part of your investment. Prices typically range from $5,000 to $18,000, depending on:

• Power output (measured in kilowatts or kW)
• Brand and model
• Optional features like noise reduction or Wi-Fi monitoring

Most whole-house generators range between 22kW and 48kW. For example, a 26kW Generac generator might cost around $5,400, while higher-capacity models can push the cost toward the upper end of the price range.

2. Installation Costs

After purchasing the generator, you’ll need a licensed professional to install it correctly. Installation costs can range from $1,500 to $5,000, depending on:

• Labor rates in your area
• Site access and preparation needs
• Electrical and gas line connections
• System complexity, such as tying into an existing panel or upgrading your home’s electrical infrastructure

At JP Electrical, we provide transparent estimates and walk you through every step of the process, ensuring there are no hidden costs or last-minute surprises.

3. Additional Costs to Factor In

Beyond the generator and installation, several other costs may apply:

Transfer Switch Installation

A transfer switch automatically switches your home’s power source from the utility grid to your generator. It’s a critical safety and convenience feature, costing between $500 and $2,000, including installation.

Permitting Fees

Most municipalities require permits for generator installation. These typically range from $50 to $200, depending on your location’s specific regulations.

Site Preparation

If your home doesn’t already have a designated location for the generator, you may need to install a concrete pad or gravel base. This ensures the unit sits level and meets safety codes. Site prep costs can vary widely based on your yard’s condition and grading requirements.

Is a Whole-House Generator Worth the Cost?

While a whole-house generator is a significant investment, it delivers substantial value in return:

• Comfort during outages
• Protection of essential electronics
• Security for your family
• Convenience of not having to worry about spoiled food, frozen pipes, or power restoration timelines

More than just a backup system, a generator is a long-term investment in your home and your peace of mind.
