Horizontal Furnaces

A horizontal furnace is a heating system engineered for horizontal installation. Unlike traditional vertical furnaces, these units are designed to fit in tight spaces, making them an excellent choice for homes with restricted installation options.

Unlike traditional vertical furnaces, a horizontal furnace is installed on its side, with ductwork and vents extending from the sides. This unique orientation allows horizontal units to be installed in tight spaces such as homes with attics, crawl spaces, closets, or limited basement space. This flexibility allows homeowners to maximize their available space while still enjoying reliable heating. They are also a popular choice for mobile homes and multi-story residences.

With their space-saving design and versatility, horizontal furnaces offer homeowners a practical heating solution without compromising performance.

How does a horizontal furnace work?

Like vertical furnaces, it burns fuel—such as natural gas or oil—to generate heat, which is then distributed throughout the home via the ductwork system. The horizontal design ensures efficient airflow and even heat distribution, providing optimal comfort throughout the living space. Learn more on how do gas furnaces work.

Frequently Asked Questions On Horizontal Furnaces

Can you install a furnace horizontally?

Yes, you can install a furnace horizontally if it is designed for horizontal installation. Some furnaces are multi-positional, meaning they can be installed in upflow, downflow, or horizontal configurations. It's recommended to have a professional HVAC contractor perform the installation to ensure proper setup and operation.

Can a horizontal furnace be installed in a crawl space?

Yes, a horizontal furnace can be installed in a crawl space. Professional installation by an HVAC dealer is recommended to ensure proper setup, compliance with regulations, and optimal performance.

Which way does air flow in horizontal furnace?

In a horizontal furnace, the direction of air flow can be either left-to-right or right-to-left, depending on the design and installation requirements. The airflow direction is determined by the specific configuration of the furnace and the layout of the ductwork.

What is the filter direction for a horizontal furnace?

The filter direction for a horizontal furnace should follow the direction of the airflow. The filter typically has an arrow indicating the correct orientation. Place the filter so that the arrow points in the direction of the airflow, which means:

Left-to-Right Airflow: The arrow on the filter should point to the right.

Right-to-Left Airflow: The arrow on the filter should point to the left.

Can you install a horizontal furnace in attic?
