5 Attic Fan Installation Questions to Ask a Pro

Proper ventilation is essential to maintaining a consistent temperature in your home and keeping humidity levels in the attic down. Attic fans help air circulate, which helps to achieve ideal attic conditions. If you’re installing an attic fan, it’s important to talk to your contractor about these questions.  

1. What type of attic fan do you want to install?

Attic fans range from $75 to $1,000 plus installation costs, depending on the type of fan you’re installing. Simple attic fans are at the low end of the range, while solar-powered and dual-powered attic fans use solar or solar and electric power to run the fan and cost toward the mid to high end. When you determine the type of attic fan you need, you should also consider the size of the attic and how efficient you need the fan to be.  

2. How much does attic fan installation cost?

The normal cost range to install an attic fan falls between $370 and $920 but averages about $625. You can discuss these costs with your pro and get an estimate for how much the labor costs will affect the final price. You can also choose to add on some additional features like an automatic shutter, thermostat, roof fan cap, humidistat, and additional insulation for better attic fan performance.  

3. When would you like your attic fan installed?

Because installing an attic fan will require creating an opening in the attic roof, weather is a consideration when you decide when you would like this work done. You can ask your local attic fan installation pro, typically an HVAC contractor or local roofing company, when they can complete the work and adjust your schedule accordingly. You may need to look ahead in the forecast to find a day that works best.  

4. Will you provide the materials?

Your contractor can order the attic fan for you, but if you choose to purchase one on your own, make sure you notify them in your initial discussions. Purchasing your own materials may save you some money, but it’s important that you get the right things so the contractor isn’t waiting for parts they need, which can stall their work.

5. How many attic fans do I need?

Knowing how much ventilation your attic needs is a good place to start. Typically, an attic needs one square foot of ventilation per 300 square feet of attic space. Ventilation can be achieved through roof vents, soffits, and attic fans. Your contractor can assess your home and help you decide how many attic fans you need to manage the air temperature and humidity in the attic.
