What is the difference between 2 stage and variable speed?

A two-stage furnace has low and high stages of operation. During the low stage, the furnace uses as little energy as possible to heat your home. A variable-speed furnace contains a computerized blower motor chip that monitors the airflow inside your home to determine how much heat to generate and release.

Is a variable speed furnace the same as a two-stage?

FYI: “Variable Speed” refers to the blower motor – how much air it moves through the ductwork. “Two-Stage” refers to the gas valve and burners – basically how much heat the furnace puts out.

Is a 2 stage furnace worth the extra cost?

While it is true, a two-stage furnace costs more when it comes to purchasing and installation, and it will save you money long term. It also reduces temperature fluctuation at the house and will heat the home and let it cool when it is less cold outside and work in a more “intelligent” way than a one-stage furnace.

Should you get a variable speed furnace?

Is a 2-stage furnace better?

The ability to switch between two power modes makes two-stage furnaces more energy-efficient than their single-stage counterparts. The low power mode allows the unit to conserve energy as well as reduce temperature fluctuations and uneven heating in your home.

How does a 2-stage variable speed furnace work?

The Variable Speed or Two Stage Furnace uses a multi-stage gas valve to give two levels of heat output depending on how cold it is in your home. The colder it gets the more heat and airflow the Variable Speed furnace puts out very much like the gas pedal on your car.
