A Beginner’s Guide To Two Stage Furnaces

As many homeowners are becoming increasingly aware, traditional furnaces don’t always do the best job of heating a home. Fortunately, this fact has led to a number of exciting technological innovations in recent decades. If you are considering upgrading to a new furnace, read on. This article will introduce you to some helpful information about the benefits of two stage furnaces.

The Basics

A traditional furnace is capable of operating in two settings: on and off. In other words, every time the furnace turns on, it turns on full blast. That isn’t such a big deal during periods of extreme wintertime cold, but during periods of milder weather it is hardly efficient.

Two stage furnaces, on the other hand, are capable of running in two different settings. One of these is the same setting as a traditional furnace. The other, however, is an intermediate stage. In other words, a two stage furnace is also capable of running at “half power.” This ability offers a number of distinct benefits, as discussed below.

Even Heating

The biggest advantage of a two stage furnace is that it allows your HVAC system to avoid the problem commonly referred to as short cycling. This phenomenon is often encountered with traditional furnaces, especially when they are being operated under circumstances where the difference between indoor and outdoor temperatures is not that great.

The problem here is that, because the furnace is operating at full blast, it does not take long for the room with the thermostat to come up to heat, and thus for the furnace to shut off. Yet this doesn’t always give the blower system enough time to distribute that heated air to rooms located farther away from the furnace.

A two stage furnace manages to circumvent the problem of short cycling thanks to its intermediate setting. This makes it possible for the furnace to remain running for its entire cycle. That way, the blower is able to distribute heated air more evenly. This greatly reduces occurrence of temperature disparities from one room to the next.
