How much does it cost to run the fan motor?

The average fan motor will draw between 90-120 watts of power. The radon mitigation fan motor will run 24 hours a day, seven days a week, 365 days a year for your protection. Specific to Kentucky, we have some of the lowest electrical rates in the nation and that means the cost can be estimated to be between $75-$150 a year… quite a bargain.
