Signs That Your Air Ducts Are Due for Cleaning

The National Air Duct Cleaners Association recommends that you clean your air ducts at least once every three years. However, depending on usage and geographical location, some air ducts tend to get dirty more quickly than others and may need more frequent cleaning. So how will you know when your air ducts are due for cleaning?

Mold Growth in Your Furnace

Air conditioners and furnaces can provide conducive environments for mold growth. This problem is more prevalent if you live in a humid climate. Mold grows rapidly and can aggravate allergies and respiratory issues. Schedule frequent inspections to determine if your HVAC system has mold growing in it. If there are signs of mold, contact a mold professional who will thoroughly clean your home’s HVAC system and ductwork to remove mold and prevent re-growth.

Excess Dust

If you notice specks of dust on surfaces despite your cleaning efforts, chances are your ducts are dirty. It is important to take a frequent look at supply and return vents around your home for dirt and dust. Also, remove the vent covers and inspect the ductwork as frequently as possible. Should you notice signs of dirt and dust in your ductwork, call a professional HVAC contractor to undertake a thorough cleaning.

Rising Utility Costs

A sudden rise in heating and cooling costs could be caused by dirty ductwork. The ductwork accumulates debris that prevents air from flowing freely and efficiently through your home’s HVAC system. This forces the furnace and air conditioner to work harder to maintain the ideal home temperature, resulting in utility bills that are higher than normal.

Rodent or Insect Infestation

Rodents and insects can take up residence in your ductwork. Should you see, hear, or smell any indication of insect or rodent infestation, it is time to call a professional for cleaning. Common signs of pest infestation include odors from droppings, fur, shells, and husks. An infestation can damage your HVAC system and cause illness.

Noisy Ductwork

If you notice unusual noises coming from your ductwork, contact a certified professional to perform an inspection. Swooshing noises could be a sign that your ductwork is blocked by debris.
