Learn more3 types of furnaces
The type you have changes how evenly your home heats and what you pay to run it.
Single-stage
Runs at one setting: full power. A 60,000 BTU furnace puts out 60,000 BTU every time until the thermostat is happy.
2-stage
Starts on low (about 60–70% of full power) and only goes to high if needed. Most of the time it never needs high, so you get more even heat and save money.
Modulating / variable speed
Uses the outdoor temperature and your thermostat setting to deliver just the heat and airflow your home needs.
What could a 96% furnace save?
Enter roughly what you spend on heating gas in a year (check your gas bills) and your furnace's AFUE rating. Older furnaces are often around 80% or lower.

Following
Different Types Of Furnaces
Single Stage Furnace:
A single stage furnace is a furnace that only operates on a high stage. For example, if you have a 60,000 BTU furnace and the thermostat calls for heat, the furnace will be producing 60,000 BTU until the thermostat is satisfied.
2-Stage Furnace:
A 2-stage furnace has 2 BTU settings. When the thermostat calls for heat, the furnace will start on low fire (between 60-70% of high fire) for a period of time before going to the high stage if needed. For example, if you have a 100,000 BTU furnace your furnace will first run at 60,000-70,000 BTU before ramping to 100,000 BTU if needed. 80%-90% of the time your furnace will not ramp to high fire before the thermostat satisfies itself. By doing this provides a more even heat throughout your home and saves you money.
