Common Winter Problems That Can Affect Radon System Efficiency
When temperatures drop, most homeowners seal up their houses to keep warm—but that same airtight environment can cause radon levels to rise. If you have a radon mitigation system, winter is the most important time to make sure it’s working properly. Cold weather can create several problems that reduce your system’s efficiency and put your home’s air quality at risk.
Here are a few common winter issues to watch for:
1. Frozen or Blocked Vent Pipes
Snow, ice, or frost can block the exhaust pipe that allows radon gas to vent outside. When this happens, radon may build up inside your home instead of being released safely. Check your vent pipe regularly to make sure it’s clear of ice or debris, especially after a storm.
2. Power Supply Problems
Your radon fan runs continuously to keep air flowing, but power interruptions or tripped breakers can stop it without you realizing it. If your system’s fan light or indicator isn’t working, or if you don’t feel airflow, have it inspected as soon as possible.
3. Condensation and Moisture Buildup
Cold outdoor temperatures combined with warm indoor air can cause condensation in your radon system’s piping. Over time, that moisture can reduce suction, damage components, or even freeze in the pipes. Proper insulation and drainage help prevent this common winter issue.
4. Fan Failure
Radon fans work harder in winter because of increased pressure differences between indoor and outdoor air. Older fans or those exposed to extreme cold may wear out or lose efficiency. If your fan becomes unusually loud—or suddenly silent—it might be time for a replacement.
5. Changing Air Pressure in a Sealed Home
When doors and windows stay closed all winter, indoor air pressure shifts. This can affect how radon gas moves through your home and how well your system draws it out. Scheduling a radon test during winter ensures your system is keeping levels safe under real seasonal conditions.
