How to Kill Mold in Heating Vents

Mold is a potentially harmful and unsightly problem that is a common headache for homeowners. Mold thrives in dark, damp places and is typically found in bathrooms and basements. However, most homeowners do not know about the mold that is potentially growing inside their heating and cooling vents.

Heating vents can become a breeding ground for mold.

When mold is living in your heating vents, mold spores get pushed throughout your home whenever the heat is on. It is extremely important to remove all mold growing in your heating vents.

  1. Open all windows and doors to provide adequate ventilation. Have everyone leave the house prior to starting the ozone treatment.

  2. Cover all heating vents except for one in your home. Cut out cardboard in the appropriate sizes and tape it over the vents.

  3. Put on a face mask and position the nozzle of the ozone machine against the open vent. Turn the machine on and leave it on for a few hours. After a few hours of passed, turn the machine off and uncover the rest of the vents. Keep your heating system off for at least 24 hours after the treatment.

  4. Tip

    Rent an ozone machine from your local hardware or rental equipment store.
