Gas Furnace Options

80+ AFUE Forced Air Gas Furnaces with multi speed and variable speed blowers

90+ AFUE Forced Air Gas Furnaces with multi speed and variable speed blowers

Multi Speed Blowers

These blowers are installed in furnaces and typically have 4 settings available: low, medium-low, medium-high, and high speed. The speed is set by the servicing technician to accommodate your needs. Most often the fan is set at a lower speed for heating and a higher speed for cooling.


These motors are “smart” motors and are available in selected furnaces and air handlers. The variable speed blower works in conjunction with other controls to adjust the required blower speed to your home’s heating and cooling requirements. On mild days, the blower will operate at lower speeds than on hotter and colder days. The lower blower speed results in quieter operation and better filtration of the air.

AFUE – an acronym for ANNUAL FUEL UTILIZATION ENERGY, a way to compare the efficiency of furnaces. The higher the AFUE, the higher the efficiency and the lower the fuel usage, resulting in lower operating costs
