How long does a radon mitigation fan last?

How long a radon mitigation fan lasts

Published service life: 5–8 years. Roots plans for: year 7.

Service life is a planning horizon, not an expiry date. It tells you when to start budgeting, get a second quote, and stop paying for repairs on something near the end — not the day it stops working.

What changes this

One of the shortest horizons in the house on a system whose failure is completely invisible. If a home has a mitigation system, the fan is a scheduled replacement, not a repair-on-failure item.

• InterNACHI's Standard Estimated Life Expectancy Chart for Homes. Single source — the NAHB study does not list radon mitigation systems.

Service-life figures are typical estimates drawn from published industry references. Where a second reference covers the component, the figure is cross-checked against it and any disagreement is set out above; where only one reference covers it, that is stated. Actual life varies with installation, water quality, climate, and maintenance, and these figures shouldn't be relied on for insurance, lending, or warranty decisions.

Maintenance is what decides where in the range you land

The published range is wide for a reason: two identical units, installed the same day, routinely fail years apart. What separates them is upkeep.

For a radon mitigation fan, the tasks that matter most:

• Check radon fan is still running — 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.

Roots tracks the age of every component in your home alongside the upkeep that extends it, so the replacement is a planned expense instead of an emergency.
