Ducted Air Conditioning: How Does it Work


When it comes to the heat of summer, there’s only so much clothing that you can decently take off. Now, you could flout societal conventions and run around the garden in your underwear to cool off. The neighbors might not be ecstatic about that option, though.

Fortunately for us, there are alternatives. An air-conditioning unit can help you keep things at an even keel.

But what type of A.C. unit do you choose? Do you choose a split-level air conditioner or ducted air conditioning? What’s the difference? In this post, we’ll answer the question, “How does ducted air conditioner work?” That way, you know the pros and cons before choosing this option.

Ducted Air Conditioner

What is a Ducted Air Conditioner?

These are for residential use and commercial use. You place the unit in a central location, and it has a system of ducts that help heat and cool the entire home or business. A split-level model, on the other hand, cools the room it’s in and might allow some cold air to spill over into adjacent rooms.

How Does a Ducted Model Operate?

The air supply moves around a series of ducts. You put the unit in the roof, and the fan draws in the hot air. The air then passes over the cooling coil that contains coolant, and the air gets vented into the home. This process removes the heat from the air through heat transfer.

Ducted is a closed system, so the coolant is circulated through many cycles. Eventually, you may have to replace the coolant. But the main maintenance aspect here is that you clear out the intake filter regularly.

If the filter is blocked, it restricts airflow into the unit, which makes it work harder to cool the building. You pay more for your energy bill at the end of every month.

Once it’s cooled, it moves through the ducts, cooling everything. These units can be programmed to cool individual rooms or the whole house.

By contrast, you install a split-level unit into the wall of one of the rooms. There are no ducts to carry the air to other rooms.

Pros and Cons



You don’t see the unit itself or the ducts.

Versatile Programming Options

Does one person in the home prefer warmer temperatures? With these systems, you can select different temperatures in different zones.

Maintains an Even Temperature

A duct system outperforms a split-level system whenever it comes to maintaining an even temperature. The ducts circulate the air properly. With a split-level system, you have to wait for the cool air to spill out into other rooms.

Quiet Operation

This system runs very quietly.


Installation is More Expensive

There’s more work involved because you need to install the ducts. That said, your typical split-level unit only cools one or two rooms at a time, so you need several units in one home.

It’s Difficult to Fit Retroactively

Installing a duct system into an existing home is difficult.


With the right A.C. system, you don’t have to upset the neighbors by running around the garden nearly naked. Overall, a ducted system is the better bet at cooling the entire building. The installation of a duct system is easier while you’re constructing the building.

You should ensure that you get a system that allows you to set and adjust zones. It’s pointless paying to have the garage cooled if no one is in there the whole day.

Overall, if you’re looking for even temperatures, the ducted system is the way to go. If you want to cool one or two rooms, a split-level system could be more cost-effective.
