How Often Does Ductwork Need To Be Cleaned?

Posted on January 29, 2015

The air you breathe makes a difference in your quality of life. Unfortunately, the indoor air quality (IAQ) of many homes and apartments is suffering due to the airtight nature of today’s energy efficient construction. Contaminants such as dust, dander, pollen and chemical residue from everyday cleaning products are being trapped in your living spaces, sucked into your ducts and circulated throughout your home. Worse still, these contaminants are building up inside your ductwork, ensuring your long-term exposure.

Duct cleaning removes unwanted contaminants from your home, enhances IAQ and can help lengthen the lifespan of your heating and cooling systems. But it’s not something that should be done every month or even every year. In fact, the National Air Duct Cleaners Association (NADCA) says that the frequency of duct cleaning may vary depending on the conditions of your home. With that in mind, here are five factors that will affect how often you may want to consider duct cleaning.

New Home or Remodel

It may sound counterintuitive to recommend duct cleaning in a new home, but new ducts can house a number of unwanted contaminants. Heating and cooling systems are often used during the latter stages of construction, introducing a wide variety of contaminants into your ductwork before you even ever step foot in your home. These contaminants can vary depending on the type of work that was done, the chemicals used in during the construction process, and the season in which the construction took place. The same holds true for household remodeling projects.

Mold and Mildew

According to the Environmental Protection Agency (EPA), mold and mildew can grow on any organic substance, as long as oxygen and moisture are present. The nearly constant flow of oxygen and moisture through your HVAC system makes your ductwork an ideal breeding ground for mold and mildew. While a do-it-yourself visual inspection may turn up results on occasion, it’s much safer to call in a professional if you suspect a problem with mold and mildew in your ductwork. If your concerns turn out to be valid, duct cleaning may be the best course of action.

Insects or Rodents

Ducts aren’t just an ideal breeding ground for mold. Insects and rodents also enjoy the cozy confines of ductwork, and they bring their own unique brand of damage. They build nests that block airflow, and often shred flexible ducts in the process. What’s worse is they leave behind waste products that end up in the air you breathe. If you’re experiencing a problem with insects or rodents in your ductwork, have the pests professionally removed, and follow up with a certified duct cleaning service.

Living with Pets

We all love our pets, but it’s hard to deny their effect on the cleanliness of our homes. Depending on the number and types of pets you have, their bathroom habits and natural shedding tendencies, varying levels of unwanted contaminants are being introduced into your indoor air – and your ductwork. If you’ve ever had a Himalayan cat, for example, you’re probably familiar with the sight of fur rolling through your home like tumbleweed. This fur is hard enough to pick up from the floor with a vacuum, so imagine how difficult it is to remove from your ductwork. Luckily, professional duct cleaning provides a solution.

Asthma and Allergy Sufferers

If someone in your home suffers from asthma or allergies, you probably understand the importance of air quality more than most. While routine cleaning and the removal of irritants from the home can help alleviate asthma and allergy symptoms, there will always be leftover residue in your ductwork. Duct cleaning removes these contaminants and prevents them from spreading through the air in your home.
