When the power goes out, a home generator can be a lifesaver—keeping lights on, food fresh, and essential devices running. But before you enjoy that peace of mind, it's important to understand the costs involved in installing a generator. This guide breaks down the average costs, what factors influence the price, and tips to help you plan your budget.
Average Cost to Install a Home Generator
The total cost to install a home generator typically ranges from $3,000 to $15,000, depending on the type of generator and installation complexity. Here’s a breakdown:
Portable Generators: $500 to $2,500 (excluding optional transfer switch)
Standby Generators: $5,000 to $15,000 (including installation)
Installation Only: $1,500 to $5,000 (for standby units)
Most homeowners choose a standby generator, which is permanently installed and turns on automatically when the power goes out. While they’re more expensive than portable models, they offer more power and convenience.
Factors That Affect Installation Cost
Several elements can influence how much you’ll spend on installing a home generator:
1. Type and Size of Generator
The bigger the generator, the higher the cost. A small 7kW unit may cost around $2,500, while a 22kW whole-house generator can exceed $10,000. Larger units require more fuel and higher-capacity transfer switches.
2. Fuel Source
Generators can run on natural gas, propane, diesel, or gasoline. Connecting to a natural gas line is convenient but may require additional plumbing work. Propane tanks or diesel tanks also come with extra installation costs.
3. Transfer Switch
A transfer switch is what connects the generator to your home’s electrical system. A manual switch can cost $300–$500, while an automatic one may cost $1,000 or more (not including labor).
4. Permits and Local Codes
Depending on your location, you may need permits for electrical and gas work, adding $100–$500 or more to your project.
5. Site Preparation
Installing a concrete pad, leveling the ground, or building a small enclosure can add $500–$1,000.
What’s Included in Installation?
A typical professional generator installation includes:
Delivery and placement of the unit
Wiring the generator to the transfer switch
Connecting to fuel source (natural gas or propane)
System testing and safety checks
Local permits and inspections (if required)
Be sure to get a full estimate that includes all these elements to avoid hidden costs.
How to Save on Generator Installation
Shop Around: Get multiple quotes from licensed installers.
Look for Rebates: Some utility companies or local governments offer incentives.
Choose the Right Size: Don’t overpay for a larger unit if your home doesn’t need it.
Final Thoughts
Installing a home generator is a smart investment in comfort and safety, especially if you live in an area prone to power outages. While the upfront cost can seem high, the long-term benefits of uninterrupted power are well worth it. By understanding the installation costs and planning ahead, you can ensure your home stays powered—no matter the weather.
