If you continuously find yourself needing to dust off the registers in your home and you are noticing more and more dust buildup on the furniture, then you may want to look into the condition of your ducts. If your ducts have dust in them, then that dust will blow out every time that the HVAC system turns on. Here are some of the things that you are going to want to look for in order to prevent further issues, and things you want to do to take care of the current issue.
Check the air filter
The first and easiest thing that you are going to want to do is to check the air filter. If you find that it is dirty, then replace it with a clean one to see if this fixes the issue for you. If you don't notice an improvement in the amount of dust, then you can move on to the next step.
Check your duct work for repair issues
If you have found the air filter to be clean, then there is some way that the dust continues to get into the system. One of the next things that you are going to want to look for are any issues with your duct work that would allow dust to enter the system.
If you have a leak in the duct work, then not only will air be able to leak out of the system which will cost you more money on electricity, but air can also enter the system. When that air enters through the duct work leak without going through the filter first, then that air can contain a lot of dust. The dust will cling to the sides of the duct work at first, then much of it can be blown out through the registers.
The easiest way to find out if there are leaks is to have an HVAC tech come out. However, if you want to try to find them yourself first, then you want to follow your duct work that is generally in the crawlspaces and feel for hot air escaping when the system comes on. You can temporarily stop the leak with duct tape until a technician can get out to check things out.
Have your duct work cleaned when needed
If you haven't had your system cleaned in a while, then you may just need to have it cleaned. When you have dirty duct work, then you should have a professional come out to clean the whole system for you.
