The complete buyer’s guide to furnaces – Single vs. Variable Speed Furnace Blowers

Buying a new furnace or replacing your current one can become a very complicated process with all of the technical terms being tossed around. But when deciding on which furnace to purchase, you should know the difference between a single speed and a variable speed furnace. These speeds are actually referring to the blower within the furnace. Let’s take a look at how these two types of furnaces differ and which one is better for you.

Single Speed Furnace

Also known as a 1-stage furnace, the single state means the furnace only has one setting, high. This means that whenever it is operating, it’s running at full capacity, no matter how cold it is outside. A single stage furnace is not as efficient because it is working at full blast to produce as much energy as possible every single time it is turned on.

Variable Speed Furnace

With a variable speed furnace however, the ‘variable’ refers to the furnace’s indoor blower motor. It simply means that the blower motor operates at different speeds to more accurately control the flow of heated air to your home. This advanced technology is able to constantly monitor and adjust its blower settings to account for things in your home that restrict airflow, such as your ductwork, furnace location and even dirty filters.

Being able to constantly adjust the blower motor could be a huge energy and money saver since your furnace will run much more efficiently. These types of furnaces also allow you to set the thermostat on different settings for various parts of your home.

A variable speed furnace provides a more consistent comfort level as it removes the possibility of temperature swings. The variable-capacity function is like cruise control for your furnace’s operation and the automatic adjustments is what makes this type of furnace deliver maximum fuel efficiency.

Furthermore, even when the furnace is not on, the motor in a variable speed furnace can be in constant operation so that it will continue to circulate the air in your home 24/7 providing higher air quality. The more air that goes through the filter, the more contaminants are being removed. In addition, since the furnace is providing a continuous, warm airflow, that air is constantly being redistributed meaning your furnace does not have to operate as often. Another money saving benefit.

Clearly, variable speed is the ultimate choice when it comes to deciding on an energy efficient furnace. While they cost more upfront, they pay for themselves in the long run.
