The Importance of HVAC Duct Cleaning

HVAC Duct Cleaning Improves Indoor Air Quality

You spend close to 90% of your time indoors. According to the EPA (Environmental Protection Agency), indoor air quality is five to eight times more polluted than the air outdoors. In the Texas Gulf Coast, some areas may be higher than the norm.

Indoor air quality is affected by cooking odors, pet smells, and other airborne pollutants. Contaminants in your home can include pet dander, pollen, dust, debris, virus and bacteria particles, mold and mildew spores, chemicals, and more.

Your HVAC air filter will catch and remove most of this, especially HEPA or high-efficiency particulate air filters. If you do not change your air filter on a regular basis, these contaminants begin to build-up in your ductwork.

For that reason, it is important to have HVAC duct cleaning to remove these contaminants that have built-up in your HVAC system. HVAC duct cleaning will drastically improve your indoor air quality by reducing indoor air pollutants, allergens, and pathogens in your home.

Remove Airflow Obstructions in Your Ductwork

Dust and debris will hinder efficient airflow in your HVAC system. Restricted airflow due to ductwork dust and debris will cause your HVAC system to strain to work hard to achieve the same desired result. Excessive strain will shorten the life of your air conditioning system. A clogged or dirty air filter will have the same results on your HVAC system.

Restricted airflow will create excess wear and tear on your air conditioning system components. In addition to dust and debris in your ductwork, pest carcasses, pest feces, or nesting material can obstruct airflow within your ductwork. Evidence of insect or rodent infestations need to be addressed immediately.

How Often Should HVAC Ductwork Cleaning Occur

The NADCA, National Air Duct Cleaners Association, suggests that your HVAC ductwork should be cleaned every five years. Each home will differ depending on:

HVAC Ductwork Cleaning Energy Savings

According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating or cooling a home is wasted. Contaminants in the heating and cooling system cause it to work harder and shorten the life of your system. Although filters are used, the heating and cooling system still gets dirty through normal use.

When an HVAC system is clean, it does not have to work as hard to maintain the temperature you desire. As a result, less energy is used, leading to improved cost-effectiveness.

Proper Cleaning Methods

HVAC Duct Cleaning has two primary components: breaking loose debris and removing the debris.

Breaking Loose Debris During HVAC Duct Cleaning

HVAC system cleaning requires eliminating the source of contamination. HVAC duct cleaning begins with using a ductwork agitation device to loosen contaminants from the inner surface of your air conditioning system ducts.

Depending on the HVAC duct cleaning system, the agitation device may vary. System devices can include brushes, air whips, hand-brushing, contact vacuuming, and compressed air nozzles or “skipper balls.”

Removing of Contaminant Debris

During the HVAC ductwork cleaning process, your air conditioning system is placed under negative pressure preventing the spreading of pollutants to other components of the system or throughout your home. Continuous negative pressure allows the fine particles to be removed once airborne so that they are not released back into your living space once your HVAC system is turned on again.

NADCA’s rule of thumb for consumers is that “if your air ducts look dirty, they probably are,” and that dirty HVAC systems should be inspected by a reputable, certified HVAC professional. Below are some other reasons homeowners choose to have their air ducts cleaned.
