Do You Need Air Duct Cleaning?

Prior to deciding should you get the air ductwork cleaned, you should know just a little about how exactly they work and why they collect grime.

Most houses are heated utilizing a furnace along with a duct system that distributes heat into different rooms. This technique consists of both "return" ducting that bring cold air to your furnace and "supply" ducting that distributes heated air throughout your house.

It is simple to differentiate between return and offer ducting by heading down for your basement and checking the sheet metal ducting usually found hanging in the floor joists around the ceiling.

The return duct is generally a large rectangle that's connected to the bottom of the furnace, as the supply duct arrives the top furnace. The provision duct is generally comprised of a sizable "trunk" duct around the ceiling, together with more compact metal ductwork that branch off into each heated room. You will find them frequently included in metallic grate on the ground or even the wall.
