Replacing a radon mitigation fan usually runs between $200 and $500 for the part alone, but total cost climbs with labor and any ductwork adjustments. I've seen quotes from $800 to $2,500 depending on your home's setup and local rates. Getting a few estimates helps avoid surprises, especially if the fan is in an attic or requires electrical work. Proper sizing matters—too small won't pull enough radon, too big wastes energy.
