When it comes to HVAC systems, many homeowners are familiar with the major components such as the furnace, air conditioner, or heat pump. However, one crucial part that often goes unnoticed is the air handler. Understanding what an air handler is and how it functions can help you maintain your HVAC system and know when it’s time for repairs or maintenance.
What Is an Air Handler?
An air handler is a key component of your HVAC system for circulating conditioned air throughout your home. It works alongside your air conditioner or heat pump to deliver heated or cooled air via a network of ducts. Essentially, it’s the indoor part of the system that moves air to ensure your home stays comfortable year-round.
Typically located in the attic, basement, or a dedicated closet, an air handler consists of several internal parts, including the blower, air filter, evaporator coil, and sometimes heating elements. Each of these components plays an important role in delivering consistent and efficient airflow.
How Does the Air Handler Work?
The air handler works in conjunction with your outdoor HVAC unit. When your thermostat signals a need for heating or cooling, the outdoor unit gets to work either absorbing or releasing heat. The air handler blower motor then draws in air from your home, passes it through the evaporator coil where it is cooled (or heated, in the case of a heat pump), and pushes the conditioned air back into the ducts, where it’s distributed throughout your living spaces.
In some cases, air handlers are equipped with auxiliary heating strips, which can provide supplemental heat in colder climates or on particularly chilly days.
Signs Your Air Handler Needs Repair
Like any other HVAC component, the air handler can experience wear and tear over time. Some common signs that your air handler might need attention include:
- Weak airflow: If the air from your vents feels weak or inconsistent, it could indicate a problem with the blower motor or evaporator coil.
- Unusual noises: The air handlers’ banging, clanging, or whirring sounds may point to loose or damaged parts that need to be repaired.
- Inconsistent temperatures: If some rooms in your home feel hotter or colder than others, there may be an issue with the air handlers’ ability to distribute air evenly.
- Increased energy bills: A malfunctioning air handler can cause your system to work harder, leading to higher energy costs.
