You’re probably familiar with a few basic terms that relate to your cooling and heating system. Forced air and central air are two that are often used interchangeably, yet are not quite the same. Here’s what you should know about each so that you can better care for and understand your system.

The Differences Between Central & Forced Air

What Is a Forced Air System?

A forced air system is any type of HVAC product that depends on air ducts and vents to deliver air throughout the property. Furnaces use forced air systems to extract cold air from outside the home and then warm it during the heat exchange process. The furnace then blows this warmed air through the ducts and vents to warm the space. Heat pumps that rely on ducts to deliver warmth are also considered forced air systems. Even central air conditioners fall into this category because they depend on the very same ducts and vents to supply cool air throughout the house.

What Is a Central Air System?

The exterior component contains the vital compressor, condenser, and evaporator coils, which extract hot air from outside, cools it through a refrigerant cycle, and disperses it throughout the home via the ductwork.

What Is the Key Difference?

Both forced and central air systems perform similar functions for heating and cooling the house, respectively. Forced air, however, is more of an umbrella category that includes the central AC. By contrast, the central system refers only to the cooling product designed to lower your home’s temperature. It shares the same duct and vent system that your furnace uses to warm the home.
