Ductwork is an essential part of the HVAC systems in most homes. Cold air from the air conditioner and hot air from the heater need to be distributed throughout the house, and ductwork is how that is done. A blower fan pushes the air through the ducts and it comes out the vents in the various rooms, cooling or heating the house.
As long as you get plenty of cold or hot air, you might never think about your ducts. They’re usually hidden away behind walls or in attic spaces. And even if you can see the outside of them, you certainly can’t see the inside. What is going on in your ductwork? Could mold be growing in there? Do you need duct cleaning?
