What the Pros Say
"I've seen these alarms catch problems we wouldn't have found otherwise, like a bird's nest deep in the line. It's a great early warning system that tells you *when* to call us, not *if*."
M
Mike Johnson
Dryer Vent Technician, 15 years"We recommend alarms as a supplement to annual service. It gives homeowners peace of mind and helps them understand their dryer's performance, but it doesn't replace a thorough, professional cleaning."
S
Sarah Chen
Service Manager"The best monitors use back-pressure sensors. As lint builds up, airflow is restricted, pressure increases, and the alarm trips. It's simple, reliable physics that provides a clear indicator of a problem."
C
Carlos Rodriguez
Master Technician"For our multi-family properties, these monitors are a no-brainer for liability and efficiency. It's an affordable safety upgrade that pays for itself in energy savings and preventing a catastrophic fire."
