Why Switch to a Two-Stage Gas Furnace: A Feature on the Lennox EL296V

Posted: 2018-12-04

If you’re a homeowner looking for ways to save money on heating while keeping a toasty, snug home, you might want to consider upgrading to an energy-efficient two-stage heating system.

Four Seasons Air Specialists is your trusted heating company in Shoreview MN that carries a full range of cost-effective furnaces designed by Lennox Industries.

This article will focus on the benefits you get out of a two-stage gas furnace.


The term “stage” refers to the burner mechanism within a furnace. It relates to the valve that controls the flow of fuel to the burner itself. A traditional, single-stage furnace only has two positions, which are opened or closed.

On the other hand, a modern, two-stage furnace has three distinct positions: fully opened, partly opened, and closed. This feature allows the furnace to either function at full capacity just like a traditional one, or at a reduced output where it lessens fuel consumption while providing about 60 to 65 percent of the heating of its full capacity. If the heating system has not yet provided your desired temperature, it will accelerate to full power, wherein it will finally get the job done.

Benefits of a Two-Stage Gas Furnace

The most obvious benefit of upgrading to a newer, more energy-efficient two-stage furnace is reflected on your monthly utility costs. When the outside temperature is moderately cold, the furnace will run on partly open mode instead of running on full blast mode. This results in less energy consumption, which ultimately saves you money.

In addition to lower heating costs, a two-stage furnace will also distribute a more consistent heating throughout your home — even when it’s not on fully open mode. This allows for more even heating with much smaller temperature changes. On the other hand, a single furnace will quickly heat your home and then turn off faster, making considerable temperature fluctuations all throughout the home.

Single-stage furnaces have a much lower life expectancy because of the fact that they always work at full capacity. Another factor is that a traditional heating system turns itself on and off too frequently, which increases the furnace’s wear and tear. On the other hand, a two-stage furnace operates much better by decreasing the instances of system short cycling. This puts less pressure on the furnace, which helps abate the chances of system failure.

Moreover, a less obvious benefit of a two-stage furnace is its ability to better filter the air in your home. That’s because a two-stage unit works more often compared to a single-stage unit. By doing so, it pushes more air through your ductwork, distributing more air and filtering it much more efficiently.
