What’s the Deal With My Dusty House?
There is a lot that goes into maintaining a home. One thing that all homeowners should work to ensure is that they do not have a dusty house. Even with regular cleaning, there is a chance that you still have a very dusty house. Or, after a day or two of rooms looking clean, you may find yourself exclaiming something like, “Why does my house get so dusty so fast?”
The truth is, even with regular cleaning, certain causes can lead you to have a continually dusty home. Here are some things to know about why your house is always dusty and how to eliminate those causes.
In some cases, the reason the house is very dusty is because you may not be vacuuming carpeting as often or as thoroughly as you think you are. It is important to keep in mind that carpets and rugs can harbor a lot of dust, and the more they are walked on, the more likely that dust is to get kicked into the air and around to other parts of the home. this, in turn, may lead to the whole house being always dusty.
However, carpeting is a small issue compared to other dusty house causes. The bigger reasons your house is so dusty all relate back to the same culprit: your HVAC system.
Your HVAC system is essentially the lungs of your home—it brings air in and lets air out into your home to heat or cool accordingly. To properly function, the HVAC system has many working parts which, if not maintained properly, can lead to a very dusty house.
The first thing to note is the importance of regularly changing your air filters. These filters help to collect dirt and other particles and keep them from floating around the air in your home. Over time, they become dirty and need to be replaced; otherwise, your HVAC system will not be able to work properly. This not only means your HVAC will not work efficiently, but it also means dust has nowhere to go and will accumulate within the house.
Another, potentially much-bigger reason for why your house is so dusty all the time is because your ductwork isn’t properly sealed. Since air travels through the ducts and into your home, dust and debris can enter from outside. As a result, your house will become dusty, and no amount of cleaning will stop it from building up again.
When your HVAC system is connected to leaky ductwork, it allows air to enter the system without going through the air filter meant to catch dirt and debris. As a result, your HVAC system will be releasing dirty air into your home, which is in large part why your house is so dusty all the time.
Similarly, if there are any leaks around your doors or windows, this can also allow dust to enter and create a dusty home. This dust can also be sucked into the ductwork as it circulates in the air, spreading it to other areas of the home and leaving you saying, ”My house is so dusty.”
Having a dusty house is something nobody wants to deal with. Not only does it leave you feeling like your home isn’t clean, even if it is, but it can cause or aggravate different health issues.
For one, when a house is always dusty, it can cause things like eye irritation, coughing, sneezing and even hay fever. It can also cause or worsen asthma attacks or other respiratory problems like chronic obstructive pulmonary disease (COPD).
While there is still no hard evidence about the long term effect of dust on asthma, when a person who lives in a dusty house regularly breathes in the dirty air, they can begin suffering from issues like reduced lung function.
Understanding why your house gets so dusty is just part of the process. The other part is eliminating those causes.
The biggest step to take in eliminating dust from your home is to seal your HVAC system’s ductwork. By sealing the leaks that may exist, you are ensuring there is less of a chance for a dusty house. Aeroseal is an innovative duct-sealing product meant to solve the “why is my house dusty” issue. It works by entering the ductwork and automatically finding and sealing all leaks for immediate results.
Once the ducts are sealed, you should consider cleaning the ductwork and replacing your air filter so that you have a fresh start and will no longer have to wonder what’s making your house so dusty.
Another thing you can do is ensure that all the windows and doors are properly sealed so that there are no leaks that allow dust to enter the home.
There are several reasons why your house gets so dusty, and in the end, they pretty much all relate back to your HVAC system. By far the biggest culprit to a very dusty house is leaky ductwork. When you have HVAC ductwork that isn’t properly sealed, dust can easily enter the system and travel through your home, leaving you always wondering, “Why is my house dusty?” By fixing leaky ductwork, changing your air filter, and sealing other leaks, you are ensuring dust has little chance to enter your home, leaving you with cleaner air, a less dusty home, and a better-working HVAC system.

How Dust Enters Ductwork
Your HVAC system is located on the outside of your home, where it is surrounded by dirt, outdoor dust, dander, and other kinds of debris. The HVAC system sucks in these different elements as it works, and they end up traveling through your system’s ductwork, especially if it is full of leaks.When your HVAC system is connected to leaky ductwork, it allows air to enter the system without going through the air filter meant to catch dirt and debris.
