If you’re planning to install a new furnace in your home, start by choosing which furnace type is best. Your home’s configuration and your annual heat usage are two key factors in this decision-making process. Keep reading to see how you can stay warm all winter long.
The Airflow Furnace Basics
The main difference between a downflow furnace vs an upflow furnace is the direction of airflow input and output. Here’s a breakdown of how each furnace type works:
- Air enters the furnace from the top
- The air is heated in the heat exchanger
- The heated air travels through the bottom of the furnace and into your ductwork where it circulates throughout your home
- Air enters the furnace from the bottom
- The air heats up in the heat exchanger
- The heated air exits the furnace from the top and circulates through your ductwork
Downflow Furnaces: A More Efficient Choice for the Attic
Downflow furnaces are installed in attics because the warm air produced travels downward. Since heat naturally rises, the configurations of a downflow furnace force it to do more work as it pushes air downward. By going against the grain, downflow furnaces use more energy and undergo more wear and tear during operation. Downflow furnaces are ideal for homes in warmer climates because they require less frequent furnace use.
Upflow Furnaces: Ideal for the Basement
Upflow furnaces are installed in basements and crawl spaces because the warm air produced travels upward. Since heat naturally rises, the configurations of an upflow furnace enable it to do less work. This means the unit uses less energy and experiences less wear and tear. Upflow furnaces are better for homes in colder climates since they require more frequent furnace use.
Downflow vs Upflow Furnace Pros & Cons
Below are the main advantages and disadvantages you should consider before choosing between a downflow furnace vs an upflow furnace.
- Can be installed in any type of home
- Less energy-efficient
- Less cost-effective to operate
- Reduces furnace lifespan due to increased wear and tear
- Not effective for basements or crawl spaces
- Difficult to install
- More energy-efficient
- More cost-effective to operate

Do You Have to Choose Between a Downflow vs an Upflow Furnace?
If you’re not keen on installing an upflow or a downflow furnace, one alternative to consider is a horizontal flow furnace. Rather than the air entering and exiting through the top and bottom of the unit, it enters through one side and exits through the other. Horizontal flow furnaces offer a more flexible installation process, as they don’t have to be installed vertically.
