Home Ventilation Ducts – How Do They Work?

It’s like the arteries of our homes, delivering air to every room to keep us comfortable all year round. But how does it work? Let us explain.

The Air Handler

First, the duct system begins at the air handler or furnace, where the air is sucked in and heated or cooled to the desired temperature. It’s like a giant snorting nose, inhaling air and filtering it through a labyrinth of ducts.

Series Of Ducts

Next, the conditioned air travels through a series of ducts that branch off into smaller and smaller tubes like a spider’s web until every room is covered. It’s like a giant octopus, with tentacles reaching all corners of the house.

The Dampers

You must balance the duct system to ensure air is evenly distributed throughout the home. Otherwise, you may have one room feeling like a sauna while the other is like an igloo. So, dampers regulate airflow in different areas, like a mini air traffic control center.

The Filters

But what about all that air that gets sucked in? Well, that’s where the filters come in – the duct system’s janitorial staff. They trap dust, dirt, and other particles that float around in the air, preventing them from circulating through the home. Think of them as the bouncers at a club, keeping out the riffraff.

Grills & Vents

And finally, we have the grilles and registers – the duct system’s mouth and nose, respectively. They’re the entry and exit points for the conditioned air, releasing it into the rooms and sucking it back in for another round of filtering.
