Where is the best place to install the radon fan?
(Back to top) Mock’s Radon Reduction prefers to install fans in the attic or highest unlived-in space available. The other option, which many competitors use, is to install the fan outside. The problem with this is that elements outside take away from the fan’s life expectancy in harsh climates and in some cases are not aesthetically pleasing. Fans can never be installed in the basement or below ground level.
