When it comes to furnace motors, one of the most important components of it is the blower. It’s designed to push heated air through the ducting and vents. Without it, nothing would circulate within the house. If you want to learn more about its functionality and features, consider the guide below.

What the Differences Between Blowers?

There are two types of blowers, both of which are defined by the speed of their fan’s rotation. These variations include the single speed and variable speed models. Single speeds work continuously at full energy, operating similarly to an on and off switch. The blower is triggered once the thermostat notices the temperature falls to a particular degree, which is set by the user.

With variable types, they alternate between higher and lower energy speeds, depending on how much airflow is needed to sufficiently warm up the room. However, generally speaking, its default is to run at the lowest speed.

What Should You Consider When Choosing Between Models?

A single-speed is worthwhile in smaller areas where it isn’t challenging to circulate the air. 

However, for larger, multi-room properties, variable speeds are more efficient. Since its default is to run at the lower speed, it keeps your energy usage down, which ultimately reduces your utility bills. 

The decreased energy usage of a variable speed also helps the longevity of your furnace. Since single speeds turn on and off at full energy, the abrupt cycling can wear down the other components easily. With a variable speed, you’ll have a furnace motor that’s both long-lasting and less likely to break down. 

However, if you only need to replace the blower, you may not have a choice since it’s usually best to pick the same model used by the manufacturer. Furnaces are complex appliances, and all the internal hardware must work in concert. An incompatible blower may not cooperate with the thermostat properly, and your furnace may not function at all.

For instance, using a variable speed when the original model was a single speed may only limit your new blower to only running at one speed instead. Before buying a replacement, refer to the user manual or an HVAC specialist.
