Single Stage, Two Stage or Variable Speed: What Furnace is Right for You?

March 9, 2017

When it’s time to replace your furnace, there are several factors to consider. One of the first decisions you’ll have to make is whether you want a single stage furnace, a two-stage furnace or a variable speed furnace. Since each of these systems works in different ways, it’s important to understand the differences between them to make an informed decision.

Here is some more information on single-stage, two-stage, and variable speed furnaces, along with their differences.

Single Stage Vs. Two Stage Vs. Variable Speed Furnaces

  • Single Stage: A single stage furnace only has one setting – high. That means that whenever this type of furnace kicks on, it’s running at full blast. Because they’re always running at maximum capacity regardless of the outside temperature, single stage furnaces are less energy efficient than two stage and variable speed systems.
  • Two Stage: Two-stage furnaces have both low and high settings. They operate on the low setting approximately 75% of the time, but the kick into high gear anytime an extra boost is needed to bring your home to the desired temperature. Because they run at low speed, they generally stay on for longer periods of time than single stage furnaces, but they heat homes more evenly. They’re also quieter than single stage furnaces.
  • Variable Speed: Variable speed furnaces have blower motors that operate at varying speeds to control air flow throughout the home. They constantly monitor temperature and automatically adjust blower settings as necessary. Variable speed furnaces are efficient, quiet and offer the greatest comfort for homeowners.
