Understanding Air Handler Units
An air handler, also known as an air handling unit, is the unsung hero of your air conditioning and HVAC system. It is responsible for circulating cool or warm air throughout your home, ensuring that your living space remains at a comfortable temperature. If you’re experiencing issues with your current system, you might need an air handler that works in tandem with your air conditioner or heat pump to deliver conditioned air to every corner of your home.
But what are the inner workings of an air handler unit? Let’s dive deeper into its components and how they function together to keep your home cozy and comfortable.
Components of an Air Handler Unit
At the heart of every air handler unit are three essential components: the blower motor, evaporator coil, and air filter. The blower motor is responsible for circulating conditioned air, including hot air during heating mode, through the air ducts in your home. Meanwhile, the evaporator coil serves to cool or warm the air that is drawn in through the return duct, depending on the mode of operation of the HVAC system. Finally, the air filter ensures that the air circulated by air conditioners and other HVAC systems is clean, capturing dust, and other particles from the air.
A high MERV rating filter can even inhibit the reintroduction of mold spores, pet dander, or pollen into your home, contributing to a higher seasonal energy efficiency ratio (SEER) for your HVAC system.
Adding optional components like a whole-house dehumidifier or electric heat strips to an air handler provides extra comfort and air quality benefits. These additions make it easier to control indoor levels of humidity, temperature, and air circulation. With all these components working harmoniously, your air handler unit becomes an essential part of your HVAC system, ensuring a comfortable living environment for you and your family.
How Air Handlers Work
Understanding how air handlers work is key to optimizing your HVAC system’s performance. In a nutshell, an air handler circulates and conditions air through the process of pulling it in via the air filter, passing it over the evaporator coil to remove heat and moisture or add warm air, and then pushing it back out through the blower.
Synchronizing air handlers with other HVAC equipment is of great importance for optimal functioning and to guarantee that the system is backed by the manufacturer’s warranty. That’s why it’s crucial to procure an air handler within the same communication type as your condenser to ensure seamless communication between the system components.
In reference to air handlers and HVAC equipment, “rating” denotes that the configurations on the air handler ought to be consistent with the accessible settings on the air conditioner or heat pump for optimal performance.
