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 quickly than others and may need frequent cleaning. So how will you know your air ducts are up for cleaning?

Mold Growth in Your Furnace

Ideally, air conditioners and furnaces can provide conducive environments for mold growth. This problem is more prevalent if you live in humid climates. Mold grows rapidly and can aggravate allergies and respiratory issues. Schedule frequent inspection to determine if your HVAC system has mold growing in it. If there are signs of mold, contact a mold expert 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 ducts on surfaces despite your cleaning efforts, chances are, your ducts are dirty. It is important that you 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 on 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 tons of dirt that cannot allow the air to flow freely and efficiently through your home’s HVAC system.

This forces the furnace and air conditioners to work extra to maintain the ideal home temperature. A higher performance output translates to utility bills that are higher than the standard.

Rodent or Insect Infestation

Rodents and insects can build a home in your ductworks. Should you see, hear or smell any indication of insect and rodent infestation, it is time to call a professional for some cleaning. Common signs of pest infestation include odor from droppings, furs, shells, and husks. Notably, an infestation can damage your HVAC system and cause sickness.

Noisy Ductwork

If you notice signs of noise in the ductwork, contact a certified professional to do an inspection. Swooshing noises could be a sign that your ductwork is blocked by debris.
