Does HVAC Duct Cleaning Really Do Anything?


One of the most common questions we get from homeowners is: “Does HVAC duct cleaning really do anything?” Here at Hagerstown Heating & Cooling, you can always rest assured that we never recommend services that aren’t beneficial or necessary. After all, our motto is “Honesty at its best.”

We recommend air duct cleaning be performed every 3–5 years—not nearly as often as annual HVAC maintenance. Scheduling this service every 3–5 years brings many benefits not just to your HVAC system, but to your home, family, and health as well. Let’s go over six benefits of duct cleaning.

1. Improved Indoor Air Quality (IAQ)

After several years, it’s inevitable that contaminants such as dust, pollen, pet and human dander, and even mold and mildew accumulate in your home’s ductwork. You may be thinking, “How do those things get into my air ducts in the first place?” They enter your HVAC system via tears, holes, and leaks throughout the network of air ducts. When we professionally clean your air ducts, these contaminants are removed, resulting in a major boost in your home’s IAQ.

2. Enhanced Energy Efficiency

Your ducted HVAC system is a forced-air system. That means it forces conditioned air through your ductwork before it reaches the rooms of your home. The National Air Duct Cleaners Association (NADCA) estimated that the average home can accumulate up to 40 pounds of dust every year! And when that dust, dirt, and debris accumulates, it can hinder your HVAC system’s efficiency.

3. Extended Lifespan of the HVAC System 

A layer of dust and dirt that’s 1/16” can reduce your HVAC system’s blower efficiency by as much as 20%. Clearing away all the debris that reduces your system’s efficiency has another benefit: it helps make sure your HVAC system lives for its 10–15 year lifespan through increased airflow.

4. Removal of Pests and their Debris

Roden and pest infestations are common in our area as critters love escaping the cold and snow by making nests in your warm ductwork. Duct cleaning can eliminate pests such as mice, rats, insects, roaches, and squirrels that may have taken up home in your ductwork. We’ll also clean out any remains and nesting materials. 

5. Reduction of Unpleasant Odors

Speaking of nests and remains, these can be a source of a lingering odor in homes that are experiencing a pest infestation. Mold and mildew growth along with the bacteria, dirt, and organic matter the growth can attract can also cause unpleasant odors in your home that leave you perplexed as to the source. One of the major benefits of duct cleaning is how much better your home will smell.

6. Peace of Mind

Above all else, duct cleaning gives you peace of mind knowing you’re doing everything you can to ensure your home is well-maintained along with being a safe and healthy environment for your family. Contact us to schedule your air duct cleaning today.
