The Truth on Whether Dirty Air Ducts Cause Allergies or Not

Have you been sneezing constantly or having a runny nose and itchy eyes due to allergies that aren't improving after countless visits to your doctor? Blame your dirty air ducts!

But can dirty air ducts cause allergies?

While, no, the dirty air ducts themselves do not cause your immune system to react, the dirty air ducts can cause allergy symptoms when dust, pet danders, dirt, mold, smog, dust mites, and other allergens build up in the system and are released into the air you breathe.

Also, these allergens build up in the air ducts, preventing the HVAC system from functioning correctly. Consequently, the airflow inside the house lessens, causing allergic reactions, especially in children and the elderly in your family.

That's why you must regularly have your air ducts cleaned by professionals such as Zerorez®, the Expert in the Science of Clean™!

What Is Air Duct Cleaning?

Generally speaking, air duct cleaning is cleaning cooling and heating system components such as the air ducts, drip pans, grilles, diffusers, heating and cooling coils, fan housing, and the fan motor.

So, air dirt cleaning removes dirt, dust, pet dander, mold, smog, dust mites, and other allergens from the air duct.

Can Dirty Air Ducts Cause Allergies?

According to the National Health Service (NHS), house dust mites and animal fur are some of the causes of allergies.

Suppose your air ducts become a home for allergens (allergy-causing substances). In that case, they will be distributed into the air you breathe. As a result, your home's air becomes polluted, causing allergy symptoms.

Did you know that according to the American College of Allergy, Asthma, and Immunology, every year, more than 50 million people in America get allergic reaction problems? As a result, allergies have become the 6th leading cause of chronic illness in the United States.

Does Air Duct Cleaning Reduce Allergies?

Though there's no proof that cleaning your air duct could reduce allergies, we understand that dirt, dust, and pet fur are some of the causes of allergic reactions.

Sadly, these and other allergens easily build up in the air duct.

So, if you don't clean your air ducts as often as you should, bacteria, dirt, and other allergens will build up, consequently preventing fresh air circulation.

Even though there is a lack of scientific evidence that dirty air ducts reduce allergies, most people have reported improved allergies after air duct cleaning.

What Are the Symptoms of a Dirty Air Duct?

Now that you know how air duct cleaning for allergies is vital, you also need to know the symptoms of a dirty air duct, including the growth of mold, sudden high energy bills, and poor air circulation.

Other symptoms of a dirty air duct include insect infestation and a musty smell from the air ducts.

Mold

When mold grows in the air duct, the HVAC system blows its pores into your house. Hence, mold growing in various parts of your home could indicate mold growth in the air duct.

Sudden High Energy Bills

The HVAC system uses more energy as it works harder when the air ducts are dirty, hence the high energy bills (assuming you haven't bought a new electrical device that consumes a lot of energy). If the bills have skyrocketed, it's time to call an air duct cleaning company with the best services to clean your air ducts immediately.

Poor Air Circulation

The air in your home harms your health if there's poor air flow circulation. When the HVAC system stops functioning correctly, air cooling or heating and excellent air circulation in your home ceases. Though it might take a few minutes to clean the troublesome grime in the air duct grills, it will require an expert to clean the inside of your home air ducts to stop stale air.

Musty Smell

If, after several attempts of thoroughly cleaning your house, the musty smell isn't disappearing, check your ducts. Air ducts smell!

Therefore, when you notice a musty smell, it's likely that HVAC system heat is burning the accumulated dust. Excellent cleaning of the HVAC system will solve the problem effectively.

Insect and Rat Infestation

If you've noticed a sudden increase in insect, bat, or rat infestation in your home, your air ducts could have become their home. Contact the experts as soon as possible.

Otherwise, they could damage your house or die within the air ducts, resulting in a very bad smell.

If you still have allergic reactions and allergy symptoms after numerous visits to your doctor and trying different medicines, the environment you're living in is likely a major contributing factor. This is especially true if it's in the winter, as indoor air quality is worse in the winter.

Contact the air duct cleaning company to do allergy testing for air ducts. The test will determine if dirty air ducts are causing the allergic reactions, and they'll advise on the best way forward.

You'll not only enjoy improved air circulation but also notice 'normal' energy bills and reduced allergens in your home.
