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. Lennox offers air handlers 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. 

Supplemental electric heat

Lennox® air handlers are available with an EVENHEATER® that preheats air before circulating it through your home. Heat is delivered in stages to help prevent drafts. 

Filtration options

Filtration and advanced air quality components are available for most Lennox air handlers, so you can breathe clearer and healthier air.
