Is it really necessary to check your radon fan is still running?

Yes. Roots classifies this as an essential task: skipping it eventually leads to water damage, fire risk, a safety hazard, or an expensive failure.

How often should you check your radon fan is still running?

Quick answer: Every 6 months. The system is silent whether it is working or not. The manometer on the pipe is the only way to tell, and a failed fan means the house is back to untreated radon.

Why it matters

Safety critical

This task protects people, not just the house. Do it on a schedule to make sure it gets done.

Staying on schedule matters beyond the repair bill: a consistent maintenance record is one of the factors in a home's Roots Home Health Score, and well-kept homes typically sell faster and closer to asking price.
