How Too Much Dust Can Harm Your HVAC System

When your HVAC system runs, it pulls outside air into your Liberty City, Texas, home. Unfortunately, that air may contain dust and other contaminants. Dust is actually a combination of several materials, including dead skin cells, dust mites, pollen and mold spores. Most of the time, your HVAC system’s air filter can catch this pollution. However, too much dust can cause poor airflow, unpleasant smells and health problems over time.

Too Much Dust Causes Poor Airflow

If you forget to change your air filter or if your ductwork has leaks or gaps, the filter can become clogged or dust and dirt could accumulate in your ductwork. Both of these problems reduce your HVAC system’s airflow, forcing it to work harder and use more energy. You might also deal with more dust, since your heater or air conditioner will likely spread it around your home.

Too Much Dust Causes Unpleasant Smells

Mold often has a musty smell. If you notice this smell but don’t see any mold in your home, it might be growing in the dust inside your ductwork or on your outdoor unit’s condenser coils.

You might also detect a burning smell from your furnace when you turn it on at the beginning of winter. This comes from dust that accumulates in the ductwork for your heater over the summer. It’s not a problem if it goes away in a day or two, but you should have your ducts cleaned if it lasts longer.

Too Much Dust Causes Health Problems

Dust holds a lot of viruses and bacteria, and it often causes sneezing, coughing, itchy eyes and other symptoms. Household dust may also contain lead, rodent and cockroach droppings, asbestos, pesticides, and other harmful substances. Keep it away from your HVAC system to prevent your indoor air quality from worsening.
