All About the Lennox SL297NV Gas Furnace

Posted: 2019-11-12

Are you shopping for a new furnace? You should take a look at a system that has two stages of heating — and this article will explain why.

Four Seasons Air Specialists is a leading heating company in Lino Lakes MN that offers a complete line of furnaces from Lennox Industries, including two-stage units.

Understanding Single-Stage and Two-Stage Furnaces

Traditional single-stage furnaces only run at singular capacity. It will still run at the same capacity even when the weather is milder. This results in higher energy expenses, which you don’t have to deal with if you had a two-stage system.

On the other hand, Two-stage systems operate at two separate capacities, usually high and low. The low setting is used about 75 percent of the time, while the high setting is only used when it’s extremely cold outside. Compared to a single-stage furnace, a two-stage heating system consumes less energy, allowing you to save money on heating.

Benefits of Two-Stage Furnaces

A two-stage furnace offers more consistent heating throughout your home, regardless of the setting. This allows for uniform heating with much smaller temperature changes. On the contrary, a single-stage furnace releases large amounts of heat every time the system is turned on, causing hot and cold spots in your home.

You probably have heard of the term “short cycling”. It happens when the system underperforms and turns itself on and off indiscriminately. Not only does this problem increase your energy costs, but it also abbreviates your system’s lifespan. Differently, a two-stage furnace performs much better by reducing the occurrences of system short cycling. This puts less strain on the furnace, which helps minimize the chances of premature system failure.
