If you suddenly stop hearing your radon fan, don’t ignore it.
Your radon fan should run continuously and usually makes a low, steady humming sound. If it goes silent, it could mean the fan has stopped working and that means radon gas may no longer be getting safely vented from your home.
What to do:
• Check your system’s warning device (if you have one)
• Look at the manometer (the U-shaped gauge) to see if levels have changed
• Gives us a call to replace it
A quiet fan might seem like a good thing, but in this case, silence isn’t golden. It could be putting your home back at risk. If something sounds off (or doesn’t sound at all,) give us a call to come out to evaluate and replace your fan.
