When the power goes out, everything stops. No lights, no appliances, no internet. For many homeowners, it’s not just inconvenient, it’s risky. A reliable backup generator can be the solution, but the big question is still on your mind:
What’s it going to cost me?
At Integra Electrical, we’ve been installing Generac generators in Iowa homes for more than 15 years . We understand the systems, the install process, and most importantly, how the costs break down based on real homes like yours.
In this article, you’ll find:
- What the average Generac generator costs is (with installation)
- What to expect from the manufacturer’s warranty
- The hidden fees many homeowners don’t see coming
Let’s take the guesswork out of budgeting so you can make a confident decision.
Average Price of Generac Generator
A professionally installed Generac generator can cost anywhere from $3,000 to $35,000, depending on the size of the unit and the complexity of the installation. We know, that's a big range.
That price typically includes the generator itself, a transfer switch, labor, and all the electrical and gas connections needed to power your home safely and reliably.
So why the big range? Let’s break down.
What Drives Up The Cost of a Generac Generator Install?
Several factors can push the price of your Generac generator installation toward the higher end of the range:
- Generac Generator Type & Size: Larger standby units that power your entire home cost more than smaller models designed to cover just a few essential circuits. A fully automatic system that backs up the whole home will be much more expensive than a portable generator that you plug into the home and manually start.
- Fuel Type: Natural gas, propane, and diesel all come with different setups and operational costs. The location and design of the fuel source can have a dramatic impact on cost.
- Electrical Panel & Transfer Switch: If your current panel needs to be upgraded due to the generator's electrical load, or if you want the convenience of an automatic transfer switch, you can expect additional electrical work, which adds to the total cost.
- Installation Complexity: Long wiring runs, trenching, concrete pads, and hard-to-reach locations all make the installation more labor-intensive and, as a result, more expensive.
- Permit & Code Compliance: Some local jurisdictions require specific permits, inspections, or code upgrades. These vary by location but are important to factor in from the beginning. (Des Moines City Permit Information)
What Drives The Cost Down of a Generac Generator Install?
There are also a few things that can help keep your installation costs on the lower side:
- Smaller System Size: Choosing a generator that covers just the essentials (like your refrigerator, furnace, and sump pump) requires less power and typically less labor.
- Existing Utility Setup: If your electrical panel is in good shape and there's easy access to a natural gas line, the installation process is simpler and more affordable.
- Straightforward Installation Site: A flat, accessible spot near your panel and gas meter can reduce the need for trenching, concrete work, or extra wiring.
- No Custom Add-ons: Skipping optional accessories like remote monitoring or cold-weather kits helps reduce upfront costs.
- Portable units: A portable unit that plugs into the house and requires start-up by the owner will be much lower in cost than a fully automatic system that backs up the entire home.
What About Warranties?
Generac generators come with up to an industry-leading 10-year limited warranty when registered and properly maintained.
This warranty is designed to give homeowners peace of mind, covering parts and labor for most manufacturer-related issues during the coverage period. Just keep in mind that routine maintenance is required to keep the warranty valid.
While the warranty helps protect your investment, the quality of the installation also plays a huge role in long-term reliability. A good generator installed poorly can still lead to problems down the road. (Top 5 Electricians in Des Moines, Iowa)
Hidden Fees with Generac Generators Installation
Generator quotes can look great at first glance, but it’s the fine print that often surprises homeowners. Here are a few common costs that aren’t always included in the initial price:
- Delivery & Setup Fees: Some companies charge extra to deliver the generator to your property or for crane placement if access is tight.
- Permit & Inspection Costs: Depending on where you live, permits and utility inspections may come with separate fees. These are required to ensure everything is safe and up to code.
- Concrete Pad or Base: If your generator needs a level surface or can’t sit directly on the ground, a concrete pad or composite base may be required.
- Trenching or Extended Wiring Runs: Homes with longer distances between the generator and the electrical panel may need extra trenching, conduit, or wiring, adding to labor and materials.
- Gas Line Installation or Upgrade: Connecting to your home’s natural gas or propane supply may involve meter or service line upgrades. MidAmerican Energy details the process and possible costs in their Gas Service Manual, so it’s smart to reference it early to help homeowners anticipate this potential expense.
The best way to avoid surprises? Ask for a detailed estimate that includes everything upfront, and make sure the installer walks you through what’s included.
