Radon System Making Noise? It’s Time to Investigate
If your home is equipped with a radon mitigation system, you may have wondered whether it should be making any kind of noise. If so, what noises are normal and which are a cause for concern? While a bit of low humming is completely normal, louder or unusual noises can signal that something in the system needs attention.
In this guide, we’ll break down the most common reasons a radon reduction system is making noise and what those sounds typically entail. You’ll also learn which issues are simple to troubleshoot and which ones indicate it’s time to call a professional. By the end, you’ll know exactly how to tell normal system behavior from a problem worth addressing.
Are Radon Mitigation Systems Noisy?
Radon systems are designed to produce a faint noise, but they shouldn’t be loud or distracting. Typically, the noise comes from air exiting the discharge pipe. However, this pipe is typically above your roofline, making it difficult to hear from the ground.
Another common noise you may hear is gurgling. Water can build up over time due to condensation forming in the pipe. Usually, any gurgling noise will be temporary as the pipe drains water away from the rest of the system.
Gurgling can also happen if your radon pipe was not sloped properly during installation, causing a water trap. This can often be corrected, but if the pipe runs through the walls, installing a new system may be the best option. When the pipe is routed through the walls, finding the water trap may require more invasive measures, like removing drywall.
Potential Causes of Noisy Radon Systems
When your radon mitigation system starts to make excessive noise, it’s a sign that something’s not working as it should. Whether you begin to notice loud grinding, squealing, or rattling, understanding the common sources of these sounds can help you determine your next course of action. Here are five potential causes of loud radon systems and how to address them.
Fan Age
Your radon fan is a critical component of your mitigation system, responsible for directing radon gas away from your home. These fans run constantly and usually make a low, soft humming noise. If your radon fan is loud, that may indicate it’s not working properly.
You need to address any rattling or whirring as soon as possible to prevent further wear and tear from affecting your system’s performance. If your radon fan is five to ten years old or hasn’t been properly maintained, excessive noise may indicate age-related issues and the need for a replacement.
Loose Brackets or Connections
When a radon mitigation system is installed in your home, all components need to be properly mounted throughout the attic or exterior of your home. Improperly installed fans or pipes can produce a distracting noise when the brackets become loose. Loose ductwork connections are another sign of subpar installation and typically make a whistling or hissing noise where air is escaping.
If you hear vibrational buzzing, rattling, or high-pitched squeals, visually inspect your radon system for loose brackets or connections.
System Obstructions
Bugs, dirt, leaves, and ice can get lodged in your radon fan or ductwork. These items can damage the radon fan blades or become stuck inside the PVC pipes, creating a buzzing, thumping, or scraping noise.
If you suspect that something is restricting airflow and preventing your system from working properly, give The Radon Guys a call. We can locate the source of the problem and make the necessary repairs to help keep the air inside your home clean.
Signs Your Radon System Needs Professional Service
While many radon system noises are harmless, some sounds can point to system failures that may cause radon levels to rise. Here are the key red flags to watch for so you know when to contact The Radon Guys for help.
New Loud or Strange Noises
Subtle humming noises from the radon fan are normal, but sounds that seem to come out of nowhere are a bad sign. Whether your fan is suddenly louder or you hear a grinding noise for the first time, this could mean something’s wrong and your radon system needs attention. You can rely on The Radon Guys to diagnose the problem and get your system back in working order.
Sudden Changes in Manometer Readings
Beyond distracting noises, your manometer reading suddenly spiking or dropping is another huge warning sign. Your manometer should always have one side higher than the other, as level manometer readings indicate an issue with the system’s pressure. Unusual readings require prompt attention from professionals to prevent radon levels in your home from rising to dangerous levels.
