Forced Air Furnace: Older Technology That Still Sells

27Dec

Forced air furnaces are among the most common HVAC systems in the United States, performing well in both colder northern climates and more moderate southern areas like the Gulf Coast. They are less expensive than alternative heating systems, installation is simple, and because they already use ductwork to carry warmed air throughout the house, an air conditioning unit can be easily added.

How Does It Work?

A forced air furnace consists of:

  • An air handler or blower
  • A gas-fueled or electric heating element
  • A flue (if using combustible fuels)
  • Ductwork that carries warmed air into each room
  • Separate ductwork that removes the cooled air from rooms and returns it to the system for reheating
  • An air filter to clean the air going into the system
  • A thermostat that controls when the furnace turns off and on

Although the technology behind the forced air furnace has been around since the mid-1930s, it stands the test of time, which is why it remains the most popular choice.

Pros and Cons of Forced Air Systems

A forced air furnace can quickly heat your entire home, and because it is centrally controlled with a thermostat, it keeps a relatively even temperature throughout. If maintained properly (to include well-insulated ductwork and sealing of air leaks), it is very energy efficient. The air filter can keep the room air clean and free of airborne contaminants, so a separate filtration system is not needed.

There are certain features of a forced air furnace that can be problematic. The rush of air flowing through the system can be noisy for some and depending on where vents are placed, drafts or cool spots can occur. Routine maintenance is required on the heat source, filters need replaced regularly and, as mentioned above, the duct system should be checked regularly.
