Smell or Sight
If you smell mildew or mold when you run your air conditioner or furnace, you are probably due for an air duct cleaning.
If you smell a moldy scent coming from your air ducts, have it checked out by a professional HVAC contractor. You don’t want mold migrating throughout your home through the air ducts.
Similarly, if you see dust emitting from the registers of your air ducts when you run the heat or the air, it’s probably time to clean your air ducts.
You should note, if you have flexible ducting with insulation, and you smell mold when the heating or air conditioning is running, it’s possible that the insulation is moldy. If that is the case, it is likely you will need to replace the air ducts
, or the mold will continue to spread.
Benefits of Air Duct Cleaning
When dust, dander, and contaminants build up in your ductwork, your heating and cooling system runs less efficiently. Getting the air ducts cleaned every so often will help you save money on your energy bill.
Another benefit of air duct cleaning is having cleaner air circulating through your home. If you have allergies, you may be sensitive to dust and allergens. These move throughout your home through the air ducting whenever the furnace or air conditioning is running.
