HVAC technology has advanced significantly in the past decade, mainly driven by social, economic, and environmental pressures to improve energy efficiency without sacrificing comfort. Developments in variable-speed and modulating technology in both air handlers and A/C compressors have greatly improved the efficiency of these systems. A/Cs with variable speed air handlers offer consumers many benefits including improved air quality, reliability and year-round home comfort.
An air handler or air handling unit (AHU) operates as a part of your HVAC system to move air throughout your home. They can do this with or without ductwork. Via ductwork, the air is returned to the AHU after being distributed throughout your home. If there is no ductwork, the AHU distributes and returns air directly. The AHU blows air across the evaporator coil, enabling the heat-exchange process that results in cooling and dehumidification. The motor inside the air handler enables a continuous flow of air throughout your home.
In homes with furnaces, the furnace blower usually serves as the air handler. Until variable-speed technology came along, air handlers only operated at one speed. The variable aspect refers to the fact that the motor can operate at different speeds, affecting the rate of air flow. After bringing the home to the desired temperature setting, the air handler settles into a low, continuous operation. It does not short cycle, which often happens with motors operating at 100 percent.
