Dust coming out of your vents is a common issue that many homeowners have. In this blog post, I will explain what causes it, how to fix it, and why it’s so important to remove the styrofoam from your air conditioners or turn them off in the summer.
When we use our AC units during the summertime, they blow dust into the indoor air which can be contaminated with pollutants like mold spores
. The dust particles get circulated through the whole room and then into our vents that lead outside where they are released. When this happens, you will notice that the vents around your house look like there is white dust coming out when it is windy outside.
Why are white particles coming out of AC vents?
This is due to the fact that when using air conditioning units at home, the air that comes out of your vents has a higher concentration of particulate matter than the outside air. ACS have filters and they need to be cleaned. When you don’t clean them regularly, they will act as particle accelerators.
The particles can be in two forms:
a. Dust particles from outside and inside your house which is trapped by your HVAC system.
b. Particulate matter which is released from your compressor.
Particulate matter coming from outside:
The particles come in two forms: 1 – dust particles that have been trapped inside the air conditioning units by the filter and 2 – dust particles that are released into your air conditioning units.
