Consulting with HVAC professionals can help determine the best location for your air handler based on your specific needs and building layout.

How Does an Air Handler Work?

The operation of an air handler is relatively straightforward. When your thermostat signals a need for heating or cooling, the air handler kicks into action. Here’s a step-by-step look at how it functions:

Air Intake

The air handler draws in air from the interior of the building. This process begins when the thermostat detects a temperature change and sends a signal to the air handler. The intake process is crucial as it sets the stage for filtration and conditioning, ensuring that the air moving through the system is clean and fresh.

Filtration

The air passes through filters to remove dust and other particles. Effective filtration is essential for maintaining indoor air quality and protecting the air handler’s components from dust and debris. Regular filter changes are necessary to keep the system running smoothly and to prevent blockages that can hinder airflow and efficiency.

Depending on the season, the air is either heated or cooled as it passes over the coils. This step involves heat exchange, where refrigerant absorbs or releases heat, altering the air’s temperature to meet your comfort needs. The efficiency of this process is dependent on the condition of the coils and the refrigerant levels, which should be checked regularly.

Distribution

The conditioned air is then circulated back into the building through the ductwork, maintaining a consistent indoor climate. This distribution is managed by the blower and dampers, ensuring that air reaches every part of the building evenly. Proper distribution is key to maintaining comfort, preventing hot or cold spots, and optimizing energy use.

Cycle Efficiency

This process repeats as needed, ensuring your home remains comfortable year-round. The efficiency of this cycle is greatly influenced by the quality of the air handler and the regularity of maintenance.
