Will Duct Cleaning Improve The Airflow

Air ducts have a big role in maintaining comfort and health inside the house, as they filter out the dust, dirt, and other allergens and contaminants from the house.

But even after this, due to a lack of scientific studies, people often ask us, “will duct cleaning improve the airflow?”.

Despite the lack of studies, common sense dictates that air duct cleaning actually improves the airflow inside a house. It cleans all the dust from the ducts, and also, ensures mold can not grow to a harmful degree inside the ducts. Apart from that, cleaning your air ducts will increase the lifespan of the HVAC systems and the energy efficiency of your home. 

Let’s take a detailed look at our analysis regarding the benefits of air duct cleaning. 

Does cleaning air ducts really make a difference?

When people look for the viability of an idea, they look for significant scientific studies to validate their ideas or deny them. The same is the case for air duct cleaning. But the problem here is, there are no significant scientific studies that either support or deny air duct cleaning. But if you use common sense, you can find that cleaning air ducts is in your best interest.

Since air ducts filter out the dust and dirt inside your home, over time they accumulate a lot of these particles. These can then be recirculated back into your home due to airflow inside the ducts. So, cleaning your air ducts is a no-brainer. 

Here are a few benefits of air duct cleaning that will answer your question, “does cleaning air ducts help with airflow?” 

1. Keeping the air clean

If you don’t clean your air ducts, the dirt inside them will start to pile up. And as we mentioned before, this dirt and dust will then get released back inside the house via air vents. So, will air duct cleaning reduce dust? 

Cleaning your air ducts will get rid of any dirt inside your ducts, which will keep the air inside your home clean. As a result, you don’t have to clean the dust off your furniture daily. 

2. Keeping the house healthy

Another way air duct cleaning improves airflow in the house is by making the house healthier. The dust in the air can cause allergies and other health issues for the inhabitants of the house.

Moreover, unclean and damaged air ducts have mold growing in them, which is a major cause of health hazards like allergies. If you clean your air ducts, the air flowing inside your home will neither have any dust nor will it have mold spores that can compromise your health. 

3. Removing pests

During winter, the air inside the air ducts is warm, which causes pests such as rats and insects to come inside the ducts. These animals block the way of airflow inside the ducts, causing the HVAC units to work harder.

Also, these pests bear a lot of germs, which can spread inside your home through the air. Cleaning your air ducts will remove all pests from inside the ducts and make your home healthy and comfortable. 

4. Removing foul smell

As pests reside inside your ducts, they will certainly excrete and sometimes even die there. The smell will then the carried throughout the house by the released air by the air ducts.

Also, damaged air ducts with leaks in them will have mold growing, as we said before. Molds also have a distinct smell, which can cause the house to smell bad. Will duct cleaning remove the smell, we hear you ask.

Hiring an air duct cleaning service will certainly get rid of all of these issues. 

5. Improving the HVAC system’s efficiency

The layers of dirt and dust, residing pests, and growing mold, all clog up the air ducts so much that the path of airflow inside them gets smaller with each passing day.

As a result, the HVAC units can not work properly to circulate the warm/cold air back into your house. So, they have to work harder, which causes them to burn out faster and makes them inefficient. Air duct cleaning will remove all the things that clog an air duct, improve the efficiency of the HVAC units, and increase their lifespans. It also improves the airflow, and its quality by doing so.

So, does duct cleaning improve air conditioning? Yes, it does. 

6. Increasing energy efficiency

When your HVAC units have to work harder than before, they will consume a lot more energy than before. This causes your home to be energy inefficient. Cleaning the ducts in your home will ensure the units won’t have to work too hard, and in turn, don’t have to consume a lot of energy. This will increase your house’s energy efficiency. 

Not only will this increase the energy efficiency of your home, but it will also save you a lot of money on energy bills. So, is air duct cleaning a waste of money? No, it certainly is not.
