Cost Insights:
Professional attic fan installation runs between $369 and $914, based on your fan type and home setup.
Your fan style, attic size, and roof access drive labor time, wiring needs, and the final scope.
You should budget for supplies and add-ons like shingles, vents, and a thermostat, around $150 to $400.
Hiring a local attic fan installation professional prevents leaks and electrical hazards by sealing the roof and wiring safely.
The cost to install an attic fan is $625 on average. Installing a small, passive attic fan may cost you as little as $369, but a larger solar or dual-powered attic fan can surpass $914. Contrary to what their name might suggest, attic fans help to cool your whole house—not just the attic space. They pull moisture and odors from your home, too. Let’s review how to budget for an attic fan installation.
Attic Fan Installation Cost Factors
Installing an attic fan may not be the most exciting project, but it’s one that will certainly pay off once the weather warms. While a well-chosen attic fan is reliable, its cost can vary as much as conditions in the tropics. From the size of your attic to the type of fan you install, these factors contribute to the average cost to install an attic fan.
Type of Fan
With six different types of attic fans available, costs vary considerably and can range from $75 to $1,000. Each type of fan has different installation requirements that impact total cost.
| Fan Type | Average Cost |
|---|---|
| Passive Passive fans use no electricity and work with the airflow in your home. But, because it doesn't run on electricity, a passive fan can't be connected to a thermostat, so there's no way to control its operation. | $75–$100 |
| Roof turbine Roof turbines work with your home's airflow and spin as hot air rises and pushes against the turbine. Because a roof turbine fan doesn't use electricity, it's more energy efficient (but it cannot work with a thermostat). And take note: In severe weather, rain may enter the attic through the turbine. So, if your area is prone to heavy rainfall, this may not be the best option. | $100–$150 |
| Attic exhaust Attic exhaust fans can be either passive or electric. Passive models cannot be hooked up to a thermostat, but they cost next to nothing to run as they don't use power. Electric exhaust fans are more efficient and have a thermostat control. “There are many non-electrical ventilation products for the attic,” says Bob Tschudi, Angi Expert Review Board Member and general contractor in Raleigh, NC. “For example, on hot days, cool air can flow in through a soffit vent and push warmer attic air out through the ridge and gable vents.” | $100–$450 |
| Electric attic These use electricity to run and connect to a thermostat. The thermostat tells the fan motor when to engage so your home stays comfortably cool, even on the hottest days. Because it draws power, an electric fan can ramp up your electric bill. But a quality model should be efficient and cost very little per year to operate. | $100–$450 |
| Solar While pricier than many other attic fans, solar models are super efficient because they use the sun's energy instead of electricity. A solar attic fan pays for itself very quickly in energy savings. | $300–$1,000 |
| Dual-powered This premium attic fan uses the sun's energy as its primary power source. But, if there isn't enough sunlight to adequately power the fan, it switches to electric power. | $300–$1,000 |
Size of Attic
The higher the CFM rating an attic fan has, the higher the cost will likely be. To determine the appropriate size of an attic fan for your space, you'll need to consider the size and square footage of your attic. Here's a simple guideline to help you make an informed decision:
Measure your attic: Start by measuring the length and width of your attic space in feet. Multiply these two dimensions together to calculate the square footage of the space.
Calculate the cubic feet: Determine the height of your attic from the floor to the peak of the ceiling. Multiply the square footage by the height to find the cubic footage of your attic.
Find the required CFM: Find your required cubic feet by minute (CFM) by multiplying the space’s cubic footage by 0.7. Then, consider factors like roof attributes (multiply by 0.5 for steep roofs or 0.15 for dark roofs). The resulting number represents the required attic CFM for effective ventilation.
Choose the right fan: Select an attic fan with a CFM rating that meets or exceeds the calculated value. Most fan models will indicate their CFM capacity on the packaging or product specifications.
| Attic Size | Fan Size Needed |
|---|---|
| 1,000 sq. ft. | 700 CFM |
| 1,500 sq. ft. | 1,050 CFM |
| 2,000 sq. ft. | 1,400 CFM |
Keep in mind that factors like attic insulation, climate, roof pitch (or steepness), and local building codes can also influence your choice. Consult with a professional or an attic ventilation expert for personalized recommendations to ensure optimal attic ventilation and energy efficiency.

Cost of Whole House Fans
You can install whole-house fans in a central location in the upstairs ceiling and vent it through the attic—they’ll draw hot air from the home and pull in cooler air at a rapid speed. Whole-house fans cost $300 to $1,400 or more, depending on the size and power (wattage) you need to work efficiently.
In milder climates, whole-house fans can eliminate the need for central air conditioning. They’re also more energy efficient, more cost-effective to operate, and easier to install.
Why You Should Hire an Attic Fan Installer
Almost all homeowners should hire a professional attic installer in their area, rather than attempt to install it on their own.
Here’s why it’s ideal to hire an attic fan installer
We highly recommend hiring a professional attic fan installation company or a certified electrician near you to install an attic fan in your home. Here’s why:
Creating an opening in the exterior of your home, such as the roof, invites the potential for water damage, energy loss, or pest invasions if not properly sealed. Professional installers can ensure correct sealing.
Attic fan professionals have the proper experience and tools to install these fans; homeowners without the right tools and experience can make easy mistakes that damage the fan, their exterior walls, or their roof.
Passive fans are a little safer to install, but any fans using electrical power pose serious safety hazards to homeowners without experience working with electrical systems.
Calculating the required CFM for your attic fan can be hard work; to ensure you choose the right-sized fan, work with a pro. They can recommend the proper size and power, and even brand, that meets your needs and fits your budget, works with your climate, and meets all building code requirements.
If you have prior experience working on roofs or with electrical, and feel like you have all the necessary tools and knowledge to figure out such a complex installation, it’s technically possible to complete this project yourself. Here’s how to install an attic fan if you’re up for the challenge.
How to Save Money Installing an Attic Fan
Check out these helpful ways to get the best deal on an attic fan without compromising its quality or installation.
Get Multiple Quotes
The more service quotes you compare, the more you’ll get a feel for the average cost and scope of work being offered. Plus, some companies may offer to match other quotes in order to secure your business. You may want to reach out to three to five local fan installation companies to get an estimate, then you can see which one offers the most bang for your buck.
Install During the Off-Season
If you can schedule your attic fan installation outside of peak season, which is typically spring or summer, you’ll likely get better rates. Aim for fall or winter, if possible, when contractors are more likely to have extra time and offer discounts on select services.
Check for Rebates
If you install energy-efficient or solar-powered fans, you may be eligible for incentives or rebates offered through a federal tax credit. Check with your utility company to see if they offer any additional programs for installing a solar-powered attic fan. Some federal tax credits can be as much as 30% of the purchase and installation cost of your fan.
Next Steps: Finalize Your Project With a Pro
Review the various types of attic fans with your contractor and get their recommendation for the best type for your needs and your budget.
Work with the attic fan installer to calculate the appropriate CFM for your home.
Ask if there are any building codes you’ll need to keep in mind for this install.
Make sure the pro reviews any rebates for which you’re eligible with this installation.
