Air Handler 101: Everything You Need to Know.

An air handlerair handler is a crucial component of an air conditioning system, responsible for circulating cooled or heated air throughout a building. It plays an essential role in maintaining a comfortable indoor environment, but many people are unfamiliar with this component. In this article, we'll provide you with a complete guide to air handlers, covering the basics as well as some more advanced concepts.

What is an Air Handler?

An air handler is a device used to regulate and distribute air throughout a building's HVAC (heating, ventilation, and air conditioning) system. It is responsible for controlling the temperature, humidity, and air quality of the indoor environment. It is typically composed of a fan, a filter, a heating or cooling coil, and a damper system. The air is drawn in through the filter where it is cleaned, then moved through the heating or cooling coil to adjust the temperature, and finally, it is distributed by the fan to the desired location.

Types of Air Handlers.

There are several types of air handlers, each designed for different applications. Here are some of the most commonly used air handlers:

- Single-speed air handler: this type of air handler only operates at one speed, which can be determined by the manufacturer or installer.

- Multi-speed air handler: this type of air handler has multiple speeds, which can be adjusted by the user or HVAC technician.

- Variable speed air handler: this type of air handler is designed to vary its fan speed according to the household temperature demands. The user gets to select the desired temperature and the device automatically adjusts the fan speed to maintain the ideal indoor temperature.

Components of an Air Handler.

Air Handler consists of the following components.

- Filter: It is used to trap and remove dust, pollen, and other airborne particles from the air circulating within the building.

- Blower: It acts as a fan and draws in the air and pushes it back out into the building.

- Heat exchange: Heat is either added to or removed from the air in the heat exchange coils, depending on the desired temperature.

- Ventilation: This component brings outdoor air into the building, possibly after it has been filtered and adjusted for temperature and humidity differences.

- Dampers: They regulate the flow of air through the system to ensure that the air circulates throughout the building efficiently.

Maintenance of Air Handlers.

Regular maintenance of your air handler is crucial to ensure that it stays in good working order and remains efficient. Here are some maintenance steps you can take to extend the life of your air handler:

- Replace filters regularly.

- Keep the air handler clean.

- Ensure that the coils are always clean and free from debris.

- Adjust dampers to ensure optimal airflow.

Conclusion.

An air handler is the central component of an HVAC system, responsible for circulating heated or cooled air throughout the building. With improved knowledge of your air handler and its components, you can increase its efficiency and improve the indoor air quality. Proper maintenance of the device can go a long way in ensuring its continued operation. If you have any questions regarding your air handler, don't hesitate to contact a qualified HVAC professional for advice and assistance.
