Have you ever wondered why your air still feels musty even after you've cleaned every visible surface? That's what happened to me last fall. I dusted, vacuumed, even mopped - but something was still wrong. It turned out that the fan motor was clogged with dirt. Dust, hair, mold... a whole ecosystem. As soon as I ordered a cleaning through green ductors, the difference was insane. The air became lighter and I no longer woke up with a headache. Do not underestimate this hidden mess - it really affects your health.
