Easy Radon Mitigation System Maintenance

Radon mitigation system maintenance is easy and inexpensive.

Similar to a furnace or chimney, radon reduction systems need occasional maintenance. If you have a fan powered (or active) system, you should look at your warning device, usually a manometer, on a regular basis to make sure the system is working correctly. Fans may last for five years or more — manufacturer warranties tend not to exceed five years — and may then need to be repaired or replaced. The cost to replace a fan varies as it is based on labor and materials.

To ensure the efficiency of your radon mitigation system, it is a good idea to retest your home at least every two years to be sure radon levels remain low.


Remember, the fan should NEVER be turned off; it must run continuously for the system to work correctly.

If you have a system with a heat recovery ventilator (HRV), the filter in an HRV requires periodic cleaning and should be changed twice a year. Replacement filters for an HRV are easily changed and are priced between $10 and $25. Ask your contractor where filters can be purchased. Also, the vent that brings fresh air in from the outside needs to be inspected for leavesvand debris. The ventilator should be checked annually by a heating, ventilating and air conditioning professional to make sure the air flow remains properly balanced. HRVs used for radon control should run all the time.


Get Advice for Home Renovations

If you decide to make major structural changes to your home after you have had a radon reduction system installed, such as converting an unfinished basement area into living space, ask your radon contractor whether these changes could void any warranties. If you are planning to add a new foundation for an addition to your home, ask your radon contractor what measures should be taken to ensure reduced radon levels throughout the home. After you remodel, retest in the lowest lived-in area to make sure the construction did not reduce the effectiveness of the radon reduction system.
