Do I need a Two-Stage Furnace?

Posted Feb 26th, 2020 in Heating

Do I need a Two-Stage Furnace?

Simply Put. Two Stage vs. Single Stage vs. Communicating Furnaces.

Single Stage Furnaces

Picture someone on a treadmill. Now picture that person going from a standstill to a full sprint at every work out. This is how a single stage furnace operates; there's an "off" speed and then an "on" speed. They only have one stage of heat output - high. Single stage furnaces make sense for higher temperate climates, for smaller square footage homes or tight budgets.

 
Two Stage Furnaces

This jogger starts out slow and only increases speed if needed. These two-stage furnaces operate much more efficiently. The variable or multi speed fan will slowly fill the duct work with air before speeding up to increase airflow. This will offer more even heating/cooling throughout the home. The first stage operates the majority of the time, in most climates, running at about 65% of the time. When the temperature outside becomes extremely cold and the first stage is not sufficient enough, the second stage automatically comes on for additional heat. Like finishing strong during a workout.

Modulating Furnaces

Much like the effort needed for walking a long way on a level surface, then up an slight incline, then down again. As the name suggests, the fan motor in these furnaces constantly modulates at different speeds to control the amount of air dispersed throughout the home. The temperature inside stays within two degrees at all times offering a consistent, comfortable indoor temperature. When the furnace is not "on," the motor in a modulating furnace continuously circulates air throughout the home resulting in better comfort, less energy consumption and lower utility bills.
