Adverse Effects of Dirty Air Ducts to Health

You may wonder why no matter how much you take care of yourself and your family, you all experience various symptoms that you really haven’t had before or haven’t really triggered for a long time. Well, believe it or not, these symptoms might be caused by your dirty air ducts. Some of these symptoms include:

And these symptoms may be due to a more serious health concern because of having dirty air ducts.

1. Worsen Pre-Existing Conditions

If you have family members with preexisting conditions, such as allergies, asthma or any respiratory disease, then having dirty air ducts can worsen or trigger their conditions because of the allergens circulating in your home. You may not notice it at first, but you may see your loved ones suffering from frequent asthma attacks or having a series of allergic reactions.

One way to prevent these from happening is through regular cleaning of air ducts and vents. You can call for a professional duct cleaning company to get rid of the nasty dirt build up, mold, fungi, pet dander, and allergens that can worsen your respiratory ailments.

2. Make You Tired All the Time

When you and your family are constantly exposed to air contaminated with bacteria, fungi, molds, and allergens, your immune system will start to fight back and that can make you feel more tired, unwell, and even lethargic at home.

3. Develop Sinus Conditions

If there are molds, fungi, and even dust spores growing in your HVAC unit, then that can trigger a mild type of sinus condition that may lead to sinus infections. You may notice that you and your family members feel more congested, your sinuses are more swollen, you feel some discomfort.

4. Develop a Common Cold

If you are having a lot of problems with a runny nose, sneezing and congestion, then you might be running down with a cold and it might be caused by dirty air ducts. Especially if you have symptoms like frequent sneezing, runny nose and watery eyes, for a long time, then it’s time to call for a professional to help clean those filters, vents, and air ducts.

5. Cause Skin Itchiness and Dryness
