Air Handler-Electric Furnace Basics

Air Handler, Blower Motor & Furnace Contain the Main Fan Motor that Pushes All Air to the Home

The air handler is an important part of your air conditioning equipment. Its job is to effectively circulate air throughout your entire home.

An air handler, or air handling unit, is the indoor part of an air-conditioning or heat pump system. Air handlers work much like furnaces in that they efficiently move air throughout the home. The main difference is that the air handlers only circulate heat when paired with a heat pump.

Different Types of Motors

Like furnaces, air handlers use a blower motor and fan to move conditioned air throughout the ductwork of your home. Air handlers can come with either a variable-speed or single speed blower motor: 

Variable-speed motors provide the highest level of comfort and energy efficiency. They can operate at high speeds, low speeds and anywhere in between, fine-tuning airflow based on demand. 

Single-speed motors operate at full capacity only and cycle on and off as needed to maintain your set household temperature.
