We finally move into our newly constructed home and I put a radon meter in the basement. My radon level is fairly high 12-13 and I need to put a fan/pump in. The house is 1800 sq ft. It currently has a passive radon mitigation pipe without a pump that goes down to the drain tile around the footings. I have already caulked all the seams in the basement. The mitigation pipe passes through the garage attic where a pump could be installed and vents through the roof. I was considering a a radonaway rp 145 because this seems to be about the most popular one on the market. I called the company and would not answer any of my questions because I am not a dealer. I am more than capable of installing it myself but want to make sure I pick the proper fan, there are many to chose from!!!!!!! If anybody has any knowledge of this type of system I would greatly appreciate the help. Thank you in advance!

Sorry. I don't have any experience with that system, but I always thought all you needed was some method of positive air exchange.
Is there some special consideration I'm not aware off?

Also interested...
Having just replaced my bathroom exhaust fan with an ultraquiet from Panasonic, thinking about replacing the radon fan with something quieter as well. Don't remember what I put in 12 years ago but I can hear it running every day.

Take a look at Fantech....I don't use one for radon but have two for my inline (quiet) bathroom fans...have run for well over ten years with them.

Where I work we take care of some homes with radon fans.
All were "pro installed" years ago and had RadonAway fans. Yeah, screw that company.
When they stop working we replace them with Nutone units.
Google Nutone ilf
I don't know if they are officially radon rated (if there is such a thing, like RadonAway would have you beleive) but they move air and are lasting many years for us.
Two ferncos and a wire- Well I ain't not no official radon engineer but I have the capability to replace a simple fan like this.

I have a Fantech... First one lasted about 10 years, replaced with another Fantech. It's very quiet. There's a float ball gauge in the basement that shows it's pulling a vacuum.

+1 for fantech. First one lasted ten years before bearing was making a noise. Replaced it with the same model.

My Fantech lasted about 5 years before it got noisy.
Called Fantech and they said "non-serviceable, buy a new one".
So I took it apart and found water had gotten into the motor. Replaced the rusty bearing and sealed everything up better than the factory did. It's been good for 5 years now.

Many of the big box stores now sell the Radon fans and accessories and instructions on sizing. Often it is a guess on sizing and I was told on one house I sold I might need to install two fans on a large ranch home. Radon sales ( install) during a home sale is often a way to get screwed. They of course wanted to do multiple testing over a couple of weeks. The buyer said screw this I will take the money at closing and install the system myself.

There can be an issue with radon outlet on the roof in cold climates. The warm air discharge can create a perfect setup for ice daming. Had this on my current home. Rerouted the exhaust through the garage attic side wall to resolve.q

We've always used the 4" Fantech in-line fans with the white plastic housing. That's the only fan we recommend for sub slab radon mitigation.
Note that you and also install an HRV to ventilate a basement/crawlspace. Not as good as the sub slab system but usually brings radon down a few points.

I also have a Fantech system, from the sealed sump pit and vented outside
Before I bought the house about 3 years ago, upon homeowner inspection, the basement had elevated radon readings
The previous homeowner paid for the system to be installed, which I think was around $1200

I have no clue what my radon level would be. When we had it measured during the "scare" a number of years ago we got zero. The reason being we leave the furnace fan running 24/7. The house was built in '85 and was built as a super-tight. To get a positive air exchange we use a pair of 8" earth tubes buried around the foundation.
The furnace fan draws fresh air thru the tubes and, because it runs all the time it creates a positive pressure in the whole house. No drafts or "radon leakage" as the pressure is always blowing out, not allowing anything to leak in. Free radon fan? I guess it is. Maybe something to consider... Just leave the furnace fan running.

Just a FYI, a radon fan should always be mounted outside the house. In the event of a leak or crack in the pipe, with the fan outside, the radon would still be pushed outside the house. If the fan were mounted anywhere within the house, in the event of a leak, the fan would now be pushing the radon back into the house.

Check this link out for graphes of CFM relative to power consumption.
Also if you get a fan and live in a cold(er) climate don't forget to put on a condensation bypass kit. Condensation is typically what "kills" the fan.
