How Good Is Your Pierson Air Handler?

Posted on: November 3, 2015

Not all air handlers are the same. While there are some similarities, there are distinct differences that Pierson homeowners should be aware of. At Jacob Heating & Air Conditioning, we aim to simplify your Pierson air handler so you better understand parts and repairs. Our expert staff is always available to answer any questions you may have about your specific system and guide you to the most energy efficient options for your needs. A Jacob technician is trained to correctly repair all makes and models. Here are some of the parts that might be involved in your system.

Identifying Your Pierson Air Handler

There are two main setups for air handlers that are commonly used in homes. First is the “Draw-Through” where the fan pulls air through the mixing box, filters and cooling coil before sending it through the air ducts into your home. The second type isPierson Air Handler “Blow-Through” in which the fan blows air through the mixing box, filters and cooling coil before sending it to your home. These systems mean that the highest air pressure is either before the fan in the draw through or after the fan in the blow through. Either system can be designed as a vertical or a horizontal model.

Here are some of the components that can be present in your Pierson air handler.


As the name implies, this is the outer shell that holds the rest of the components and is usually made of metal. The housing is heavily insulated to protect the system from water condensation and most likely contains a drip tray in case condensation does occur.


The size and type of fan used in the Pierson air handler will vary depending on conditions. Newer homes will probably have a variable air volume system that enables the fan to move at a high speed for heavy load or low speed for a light load. These fans systems are more energy efficient and provide the air flow volume necessary for the desired temperature.

Cooling Coil

The cooling coils are used to cool and dehumidify the air in your home. These utilize either a direct expansion or a chilled water design depending on your Pierson air handler model. Coils are arranged in rows of aluminum fins and copper tubes.


A wide range of filters can be used to remove particles and contaminants from the air. The type of filter selected is based on the system design and the needs of the home. Filters vary from the low efficiency panel to the 99.97% effective HEPA filters. Ask a technician for advice on the best filter type for your family.

Mixing Box

This is where the outside air comes together with circulated air from your home and is redistributed in the correct proportion to achieve the desired temperature.

By more clearly understanding the parts of your Pierson air handler, you can make informed decisions on needed repairs. Working together with the professional team at Jacob Heating & Air Conditioning will ensure that your home and family get the best products for ultimate home comfort.
