An air handler, also known as an air handling unit, is a device that regulates and circulates air as part of a HVAC system. It consists of a blower, furnace or A/C elements, filter racks or chambers, sound attenuators, and dampers.

An air handler works in conjunction with an air conditioner to distribute cool air throughout a home or building.

air conditioning system to circulate and regulate the air. It is an essential component that ensures proper airflow and temperature control in a heating, ventilating, and air-conditioning (HVAC) system. To understand the anatomy of an air handler, let’s delve into its different characteristics: ## Blower Unit Characteristics The blower unit is a crucial component of an air handler as it is responsible for circulating the air throughout the system. It is typically located inside the metal box and consists of a motor, fan, and blades. When the HVAC system is activated, the blower unit draws air from the surroundings and forces it through the system’s ductwork. Some key characteristics of the blower unit include: 1. Motor: The motor powers the fan blades, generating the necessary airflow for proper circulation. 2. Fan: The fan blades are designed to move a significant amount of air efficiently. 3. Blades: These blades are carefully angled to create the desired airflow pattern and airflow velocity. ## Filtration Systems Filtration systems are crucial elements in an air handler that ensure the air circulating in your home is clean and free from pollutants. They help improve indoor air quality by trapping dust, allergens, pet dander, and other airborne particles, preventing them from entering your living space. Some common filtration systems found in air handlers include: 1. Filter Racks or Chambers: These provide a designated space for installing air filters, allowing for easy maintenance and replacement. 2. Air Filters: Air filters come in various types, such as fiberglass, pleated, or HEPA filters. They capture different sizes of particles, preventing them from being distributed throughout your home and protecting your HVAC system from debris buildup. ## Heating and Cooling Elements Air handlers also include heating and cooling elements to regulate the temperature of the air being circulated. These elements work in conjunction with the blower unit to provide the desired warmth or coolness. Key heating and cooling elements in an air handler include: 1. Heating Elements: In colder climates, air handlers may contain heating elements such as electric coils or heat exchangers. These elements warm the air before it is distributed throughout your home. 2. Cooling Elements: When the air handler is part of an air conditioning system, it includes cooling elements such as an evaporator coil or refrigerant lines. These elements absorb heat from the air, creating a cooling effect. By understanding the anatomy of an air handler, including its blower unit characteristics, filtration systems, and heating/cooling elements, you gain a better understanding of how this vital component works within an HVAC system. It ensures proper airflow, ventilation, and temperature control, resulting in a comfortable and healthy indoor environment for you and your family.

Inside The Metal Box

An air handler, also known as an air handling unit, is a metal box that regulates and circulates air in a heating, ventilating, and air-conditioning system. It contains components such as a blower, furnace or A/C elements, filter racks, sound attenuators, and dampers.

This device plays a crucial role in maintaining comfort and air quality in a house or heat pump.

Inside the Metal Box An air handler, also known as an air handling unit, is a crucial component of any heating, ventilating, and air-conditioning (HVAC) system. Housed inside a large metal box, the air handler contains various elements that work together to ensure proper air regulation and circulation. Let’s take a closer look at what’s inside this metal box and the important functions they serve.

Sound Attenuators And Their Function

One of the components found inside the air handler is sound attenuators. These devices are responsible for reducing the noise generated by the HVAC system. They contain sound-absorbing materials that help minimize the sound vibrations produced by the blower and other components. By dampening the noise, sound attenuators ensure a quieter and more comfortable indoor environment for you and your family.

Understanding Dampers’ Role

Another critical component found inside the air handler is dampers. These are adjustable plates or valves that regulate the airflow within the HVAC system. Dampers control and direct the air to different areas of your home, ensuring an even and consistent temperature distribution. They play a vital role in maintaining the desired comfort levels in each room and preventing energy wastage. Dampers work by opening and closing to adjust the amount of air flowing through the system. By doing so, they enable precise control over the temperature and airflow, allowing you to create custom comfort zones within your home. This not only enhances your comfort but also helps optimize energy efficiency. In addition to controlling airflow, dampers also play a crucial role in the safety of your HVAC system. They can detect and respond to any pressure imbalances, ensuring proper ventilation and preventing potential issues. By regulating the flow of fresh air, dampers help maintain a healthy indoor environment and protect your HVAC system from damage. In conclusion, the air handler is an essential component of your HVAC system, housed inside a metal box. Sound attenuators and dampers are crucial elements found inside the air handler that contribute to a quieter, more comfortable, and energy-efficient home.

Air Handler Versus Furnace

An air handler, also known as an air handling unit, is a device used in HVAC systems to regulate and circulate air. It contains components such as a blower, furnace or A/C elements, filters, and dampers. An air handler works alongside an air conditioner to distribute cool air throughout a home.

Differences In Operation

An important distinction between an air handler and a furnace lies in their operations. A furnace is primarily responsible for generating heat, using fuel like gas or oil, and distributing warm air throughout the house via ductwork. On the other hand, an air handler works in conjunction with an air conditioner or heat pump to circulate and regulate conditioned air.

While a furnace is a standalone heating unit, an air handler is more versatile. It acts as the central component of a heating, ventilating, and air-conditioning (HVAC) system, ensuring the circulation of both warm and cool air throughout the house.

Suitability For Different Climates

The suitability of an air handler or a furnace depends on the climate in which you reside. Furnaces are commonly found in regions with cold winters, where heating is a primary concern. They efficiently generate and distribute warm air, making them an ideal choice for colder climates.

On the other hand, an air handler is well-suited for areas with both hot summers and mild winters or for individuals living in temperate climates. Since air handlers can work with both heating and cooling systems, they provide year-round comfort by distributing both warm and cool air. Additionally, air handlers often feature enhanced air filtration capabilities, which can be beneficial for those with respiratory sensitivities or allergies.
