Dirty HVAC Ducts And How They Trigger Asthma And Respiratory Complications

What is dirty HVAC ducting?

Dirty HVAC ducts are hoses, nozzles, and other fixtures with clogged or broken internal parts. When there’s a build-up of dirt, dust, or other materials inside an HVAC system, it can come back out into the atmosphere through the air vents. All this dirt, dust, and other debris can irritate the airways and cause allergies, wheezing, shortness of breath, and even bronchospasm. Dirty HVAC ducts can also collect pollutants such as particles, bacteria, and chemicals. These can get into the house through the roof, walls, and floor, and thanked HVAC ducts can end up in your living space. If you have allergies, you may notice that your house feels “dirty” even when it’s not dirty.


How Dirty HVAC Ducts Impact Health

People with dirty HVAC ducts have an increased risk of developing asthma, COPD, and other breathing diseases. These breathing disorders are all caused by an overgrowth of immune cells (mast cells and histamine) in the airways. The more likely you are to get diseases such as these, the more important it is to keep your HVAC system clean. Although it’s not always possible to clean every bit of ducting in your home, you can generally reduce your risk of getting sick by keeping the inside of your ductwork clean. Some people can handle a little dirt better than others, so experts recommend starting with simple tasks such as dusting and vacuuming the inside of your ductwork once a week. If you notice any other problems, such as wheezing or shortness of breath, then you should consult your doctor.


Signs of a Dirty HVAC System

Your HVAC system should be in good working order. That’s why it’s critical to know how your system works and what signs indicate a dirty system. Here’s how: No matter how clean your house is, it’s impossible to be absolutely certain how much dirt, dust, and other material is actually in your system. Some indoor pollutants get into your home through your HVAC system, but most of the time you won’t know for certain. So instead of worrying about whether your system is dirty or not, you should worry about your health. Any sign of pollution, whether in your house or your system, is a good reason to call your doctor. Dirty HVAC ducts can also look black or brown in color, which can indicate dirt and dust. No color is “clean” or “healthy,” so if your ducts are black or brown, it’s a good idea to clean them once a month.


Respiratory Complications due to Dirty HVAC Ducts

Your dirty HVAC system can also lead to more serious problems such as increased rates of asthma and chronic lung diseases such as emphysema and chronic bronchitis. A dirty system can collect dirt and other pollutants such as smoke and allergens that can get into your airways and cause damage. If you notice that you’re wheezing more often or that you’re having more difficult times breathing during periods of high pollen or other outdoor allergens, you should definitely get in touch with your doctor.


The Connection Between Asthma, COPD, and dirty HVAC Ducts

Some researchers believe that the link between asthma and dirty HVAC ducts is actually stronger than previously thought. According to these researchers, exposure to dust, dirt, and other pollutants can actually create an “attitude of defiance” towards normal airway defenses which may allow for more persistent airway inflammation. This leads to an increased risk of developing asthma in people with asthma, a possible explanation for the relationship between asthma and dirty HVAC ducts.

Cleaning Your Ducts Regularly cleaning your HVAC system can help reduce the impact of dirt, dust, and other pollutants on your health. It can also help reduce the amount of work that your HVAC system has to do in order to keep your home warm or cool. To clean your ducts, use a mask and filter when you’re inside. Use a mild soap or window cleaner on your outsideumptions. Make sure to rinse thoroughly off with water when you’re done. If you clean your ducts outside, be sure to clean them again after any major rains.


This cleaning is crucial in order to maintain your HVAC system’s integrity and prevent water intrusion. Change Your HVAC Filtration Your HVAC system should be able to remove a variety of pollutants, but some of the most common ones found in your home are dust, pollen, and dirt. Regularly changing your filter can help your HVAC system do its job more effectively. Change your filter once a month or whenever you see the need. If you change your filter often enough, the particles that your filter can’t get rid of will die off, leaving behind only clean, safe molecules. Inspect Your Air Hoses Your HVAC system should be able to remove a variety of pollutants, but some of the most common ones found in your home are dust, pollen, and dirt. Regularly inspecting your hoses and other internal parts of your HVAC system can help to make sure that these are in good working order. Make sure that the hoses are not too stiff or too bendy. If they’re too stiff or bendy, they can get in the way when you’re trying to move around. And make sure that none of the metal parts are covered with dirt or dust. If they are, it can create a volatile mix inside your home that can lead to harmful chemicals getting into your body.


Summary

Dirty HVAC ducts can lead to lots of problems for everyone involved. If left untreated, they can trigger asthma and other airway diseases and lead to respiratory complications. If you or someone in your household has asthma, chronic obstructive pulmonary disease (COPD), or another respiratory condition, make sure you know how dirty HVAC ducts can impact your health. Clean your HVAC system regularly to reduce the impact of dirt, dust, and other pollutants in your system.
