A Bigger Radon Fan? Bigger is Better Right?

A gimmick that has gone around for a while with Radon systems and companies trying to convince you to go with them is to up-sell you a bigger Radon fan. In our society bigger seems to always be better or the thing to do. Well, with Radon systems there is only a few cases when a bigger radon fan is the right move. First, if there is very tight soil under a basement slab such as sand and or clay then a larger vacuum fan can be needed. Extra vacuum power can move air in a tight soil condition whereas a high air volume fan, that is made for low resistance is not the best fan to use. Second, when there is a very large square footage slab, and I mean large like more than 4000 square feet it might be a good idea to use a higher air volume fan. This is mostly in commercial applications. So, if you are a homeowner and you have a 1000 to 3000 square foot slab in the basement and a Radon company is trying to sell you a bigger radon fan to give you lower Radon levels you are being scammed. Radon does not work that way. You actually don’t need to move much air to lower Radon. You just need it to move from footing to footing. A regular air volume fan will more than do the job if installed properly. Think about it. If the Radon company really cared about you, wouldn’t they install the right fan to get you the best results right away? It’s easy for them to scare you to get a “lower Radon guarantee” when it is not necessary. We offer a guarantee of 1.0 or lower for a little more money, but it does not involve a bigger radon fan, and to be honest, in most homes it’s not needed. It includes more diagnostic testing should the first post-test come in above 1.  And I tell customers that. Most homes with the right fan and piping, and gravel and or drain tile system will get below 1 Pico curie right away. Instead of offering you a fan upgrade, why not ask that they just quote you the best system with the right fan in the first place.
