How do I know if my AC is upflow or downflow?
Getting right to it, the fundamental difference between the two is in the direction of air flow in and out of the furnace. A Upflow furnace takes in existing air from the bottom of the furnace and blows out filtered warm/cool air through the top. A downflow furnace works in the opposite way.
How does a downflow unit work?
A 'Down flow' unit is one where the air is removed from the space through the top of the equipment, drawn downwards, where it is conditioned prior to being blown back into the space via the lower frontal section of the unit.
What is a downflow air handler?
Also known as “downdraft” or “counterflow” furnaces, downflow furnaces are designed to bring in cool air through the top of the air handler and release heated air from the bottom. These models are usually installed in the attic or, less often, in a closest on the home's main floor or in the garage.
What is an upflow AC?
Upflow furnaces blow heated or cooled air upward and are installed in the lowest level of your home. An upflow furnace is the best choice in cold climates where it is used for heating more than for air conditioning. Downflow furnaces blow heated or cooled air downward and are installed in attics.

These terms refer to the direction the air flows as it is taken in and heated by the furnace. So in an upflow furnace, the cool air is taken in at the bottom, warmed, and then expelled at the top. A downflow furnace, on the other hand, takes in cool air at the top and expels heated air at the bottom.

Upflow
Airflow comes in from the bottom of the air handler or furnace and flows out the top of the unit. This type of system is most common in basement installations.
Downflow
Airflow comes in at the top of the air handler or furnace and flows out the bottom of the unit. This type of unit is most common when the unit is installed in a closet.
Horizontal
The unit seems to be laying on its side and the airflow flows in from one side and out the other side. This type of system is most common in attics and craw spaces.
What is the difference between an upflow and a downflow furnace?
The primary difference between an upflow and a downflow furnace which direction they take in and expel air. A downflow furnace takes in cold air at the top of the unit and expels air at the bottom. By doing this, the downflow furnace directs heat downwards towards the area that requires it. This makes downflow furnaces naturally suited to being installed in attics. They can also be installed in the upper floors of a house if you don’t have an attic.
Why is an upflow furnace more efficient than a downflow furnace?
This makes them more efficient than downflow furnaces because they are working with the natural tendency of heat to rise upwards. Upflow furnaces tend to heat spaces more comfortably since heat moves from the floor of a room upwards.
Why do upflow furnaces work?
Upflow furnaces tend to heat spaces more comfortably since heat moves from the floor of a room upwards. This keeps the actual living area of each room more comfortable than a downflow system, which wastes heat on areas like ceilings. The downside is that upflow furnaces have more strict installation requirements.
Can you put a downflow furnace in an attic?
They can also be installed in the upper floors of a house if you don’t have an attic. This makes them very versatile, able to be installed in almost any type of home. The downside is that a downflow furnace is less efficient than an upflow furnace.
Do you need a basement for an upflow furnace?
The downside is that upflow furnaces have more strict installation requirements. Oftentimes you’ll need a basement to get the most out of an upflow furnace. This precludes a lot of homes in areas like the west coast.
Where should I put a downflow furnace?
As you may have guessed, a downflow furnace takes in air at the top of the cabinet, warms it, and then disperses it down into your home’s ductwork. As such, the placement of a downflow furnace is commonly in attic space, although it can also be placed in a garage or on the main level of a home. Some of the challenges with a downflow furnace are that installation can be more complicated, as there are stricter requirements for downflow furnaces (they also need reinforced subflooring), and they fight the natural tendency of hot air to rise. However, not all homes have a basement or crawlspace, so the benefit of a downflow furnace is that it fits with every kind of home.
What are the challenges of a downflow furnace?
Some of the challenges with a downflow furnace are that installation can be more complicated, as there are stricter requirements for downflow furnaces (they also need reinforced subflooring), and they fight the natural tendency of hot air to rise.
Why do you need an upflow furnace?
Some of the benefits of an upflow furnace are: Better energy efficiency – because heat rises, upflow furnaces tend to be more energy efficient than downflow ones.
Does air flow affect furnace placement?
It may seem like a small detail, but the way the air flows – either up or down – directly affects the placement of your furnace. If you are looking to install a new furnace for this winter’s heating, it’s important to know some basic functions of a furnace so that you can make an informed decision.
Do I need extra flooring for a basement furnace?
