This invisible, odorless and tasteless gas causes more than 20,000 deaths a year in the United States alone. If you have a radon reduction system in place, it’s important to check it once a year to make sure it’s working effectively removing this poisonous gas from your house!
If you’ve tested your home for radon and have high levels (4 pCi/L or higher) you should have a radon reduction system.
Look at the warning device on your system to make sure it is working correctly.
Check the fan and make sure that it is working. Fans will not last forever and will need to be repaired or replaced after 5-10 years. Replacing the fan in the system will cost around $250, including parts and labor.
If you use a heat recovery ventilator to increase ventilation, make sure that you are changing the filter twice a year. Replacement filters cost between $5 and $15. Remember that, like a fan, a heat recovery ventilator should run constantly for the system to work correctly.
Inspect the outside exhaust vents from your system to make sure that leaves and and other debris are not clogging the pipe.
