Is Your Radon System Still Working?
A radon fan runs all day, every day, for years. Sooner or later it wears out. When it stops, radon can build back up in your home, and there's no smell or sound to warn you. The only signs are a flat gauge on the pipe or a fan that has gone quiet.
Radon fan replacement in York, PA is a quick job. Most swaps take one to two hours. We find out why the system stopped, fit the right fan for your home and check that it's pulling air again. Then we re-test, so you know your radon level is back under 4 pCi/L.
Many York homes came with a radon system already in place when they were bought. If you don't know how old yours is, it's worth a check.

Signs Your Radon Fan Needs Attention
The Manometer Reads Level
The U-tube manometer on your pipe has liquid in it. When the fan works, one side sits higher than the other. If both sides are even, the fan isn't pulling air. The check takes 10 seconds, so glance at it once a month.
The Fan Went Silent
A radon fan should always make a low hum. If you hear nothing, check the breaker first. Sometimes it's a tripped breaker or an unplugged cord, not a dead motor.
New Noise or Rattling
A high-pitched whine, grinding or rattling means the bearings are going or the fan has come loose. A loud fan often fails soon after.
A High Re-Test
If a test comes back at 4 pCi/L or higher after years of low readings, something in the system has changed. The EPA says to re-test every two years, even when the system seems fine.
Weaker Suction Over Time
If the manometer shows less of a gap than it did when the system was new, the fan may be losing power.
Radon Fan Repair and Replacement Services
Radon Fan Replacement
We match the new fan to your pipe size and your system's pressure, then seal the couplings airtight. A fan that is too weak won't pull enough air. One that is too strong wastes power and gets noisy.
Manometer and Alarm Installs
If your system has no gauge, we add a U-tube manometer and mark the reading, so you can see at a glance that the fan is working. We can also add an alarm that sounds if the fan stops.
Pipe and Seal Repairs
Cracked couplings, loose pipe or broken seals at the floor let the system pull basement air instead of soil air. We find the leak and fix it.
System Checks for Home Buyers
If you're buying a home with a radon system, we check the fan, the manometer and the pipe, then test the air so you know it works before you close.
Passive to Active Upgrades
If your home has a radon pipe but no fan, the EPA says a fan can be added when a test comes back at 4 pCi/L or higher. We add the fan, wire it and set the gauge.

Bought a Home With a Radon System?
Many York County homes already have a radon system when they sell. That's good news, but you don't know how old the fan is or if it still works.
Start with the manometer. If the liquid sits level, the fan isn't working. Look for a tag on the pipe that shows the install date and the first reading. Most quality radon fans last 5 to 12 years, and budget fans can wear out in 3 to 5. If the fan is near that age or you can't find a date, book a system check and a radon test.

Radon Fan Replacement FAQ
How long do radon fans last?
Most quality radon fans last 5 to 12 years. Budget fans can wear out in 3 to 5 years. Fans placed in a dry spot like an attic or garage tend to last longer than fans exposed to weather. The pipe and seals usually outlast several fans.
Can I replace a radon fan myself?
Some owners do, but it's easy to get wrong. The new fan has to match your pipe size and system pressure, and every coupling has to seal airtight. Hardwired fans need safe electrical work. Some fan makers also void the warranty if a fan isn't installed by a certified tech.
Does a radon fan use a lot of power?
A radon fan runs all the time, so it adds to your power bill. Most add about $30 to $300 a year, depending on the fan model. A fan that is sized right for your home uses less power than one that is too big.
Should I re-test after a new radon fan?
Yes. The manometer shows the fan is pulling air, but it can't tell you your radon level. The EPA recommends a new radon test after any fan work to confirm your home is back below 4 pCi/L. We set that test up for you.
