Radon Huntsville › Services › Radon Fan Replacement & Repair
Radon Huntsville is the place Huntsville homeowners call when a radon fan or mitigation system quits. A certified local contractor repairs or replaces fans and fixes existing systems, including systems installed by builders or previous owners.
Radon fans run around the clock for years, so eventually most of them wear out. When a fan fails, radon can climb back to the levels you had before mitigation.
Signs your system needs attention
- The liquid in the U-tube manometer is level, or the same on both sides.
- The fan is silent, rattling, humming loudly or vibrating.
- Water is collecting in the pipe or fan housing.
- A recent radon test came back higher than after the install.
- The pipe was cracked, disconnected or crushed during roof or attic work.
What a repair visit covers
A contractor checks the fan, electrical connection, pipe joints, roof exit and seals, and measures system suction. If the fan has failed, they replace it with a model sized for your system and confirm the manometer reading. Many will recommend a follow-up radon test to confirm levels are back down.
Upgrading an older or builder-installed system
Some homes have a passive radon pipe from construction with no fan, or a system that never brought levels low enough. Adding or upgrading a fan, adding a suction point, or sealing more entry points can often improve results. See radon-resistant new construction.
Frequently asked questions
How long do radon fans last?
Many last for years of continuous operation, but lifespan varies by model and conditions. Check your manometer regularly so you know when it fails.
Can I replace a radon fan myself?
It involves electrical work and sealing the pipe correctly. Most homeowners have a certified contractor do it and confirm suction afterward.
