What is an Air Handler?

An air handler is a device used in heating, ventilation, and air conditioning (HVAC) systems to regulate and circulate air. It is typically located inside a building and works in conjunction with other HVAC components to provide a comfortable indoor environment.

How does an Air Handler work?

The air handler pulls in air from the outside or from within the building, passes it through filters to remove dust and debris, and then heats or cools the air as needed. The conditioned air is then distributed throughout the building via ductwork.

Components of an Air Handler

An air handler consists of a blower, heating and cooling elements, filters, dampers, and controls. The blower is responsible for moving the air through the system, while the heating and cooling elements adjust the temperature. Filters help to keep the air clean, dampers control the flow of air, and controls regulate the overall operation of the unit.

Types of Air Handlers

There are different types of air handlers, including single-speed, multi-speed, and variable-speed models. Single-speed air handlers operate at a constant speed, while multi-speed models have multiple settings for different airflow rates. Variable-speed air handlers can adjust their speed based on the heating or cooling needs of the building.

Benefits of an Air Handler

Air handlers help to improve indoor air quality by filtering out pollutants and allergens. They also help to maintain a consistent temperature throughout the building, leading to increased comfort for occupants. Additionally, air handlers can be energy-efficient, saving on utility costs in the long run.

Common Issues with Air Handlers

Some common issues with air handlers include clogged filters, motor problems, and ductwork leaks. Regular maintenance and inspections can help prevent these issues and ensure the air handler operates efficiently.

Conclusion

In conclusion, an air handler is a crucial component of an HVAC system that helps to regulate and circulate air for a comfortable indoor environment. By understanding how air handlers work and the benefits they provide, building owners can ensure their HVAC system operates effectively.
