What is in an Air Handler?

An air handler or an air handling unit (AHU) is an additional unit in your home to support other systems. These nifty contraptions are constructed to assist the flow of the air treated by a humidifier, furnace, or an air conditioner. What does it look like? Normally, it is a large metal box that has a blower, cooling or heating elements, filters, sound absorbers, and dampers.

Air handlers are commonly connected to a ventilation unit that is characterized by a series of ducts. They disperse air within your household and then bring it back to the AHU. Apart from this, some AHUs are created to provide and recall conditioned air within a space without using a network of ducts (called a ductless system).

Why Do I Need an Air Handler in My Home?

Air handlers are required to improve the IAQ (Indoor Air Quality) in your home. They are energy-efficient and ensure that the unit they support doesn’t have to work as hard to provide and distribute conditioned air.


Small Air Handlers vs Large Air Handlers (Types of Air Handlers)
  • Small AHUs (also referred to as terminal systems) have an air filter, blower and coil and cover a limited area.
  • Large units (also referred to as makeup air units) can condition all outside air and do not use recirculated air.
  • Rooftop units are engineered for exterior usage. As the name suggests, they are perfect for rooftop applications.
  • Custom units differ from the above. If your home’s requirements cannot be accommodated with standardized HVAC solutions, you will need innovative designs that match your performance needs. That way, you and your family won’t have to put up with poorly conditioned air, nor will you have to insert standardized units into an insufficient space.


To make it simple, ask yourself this: Do I have a split-system air conditioner or furnace? If the answer is yes, then you definitely require an AHU. Especially during the winter, air handlers ensure that you and your family have a clean, comfortable and warm indoor space with optimal distribution of air.

Tell us what you need, and we’d be happy to deliver! We stock it all – air conditioners, heat pumps, mini split, multi zone mini split, multi zone heat pumps and multi zone air conditioners. 

What is the Difference Between an Air Conditioner and an Air Handler?

Simply put, your home’s heating and cooling units are two-fold: indoor systems and outdoors systems.

Outdoor units are comprised of air conditioners, ventilators, furnaces, humidifiers, and the likes. These are geared to condition the air a certain way – whether you require warm, cool, dehumidified air, etc.

Indoor units (like air handlers) are required to distribute that conditioned air within your home in the most optimal way so as to avoid your outdoor system from having to work overtime.

In short, by shopping for a high-quality air handler from Constant, you can enjoy great air distribution within your home and beat those winter blues!
