What Is an Air Handler & How Does It Work?

While some may assume that an air handler is just another word for an air conditioner, they are two very different systems. Instead, an air handler is a critical component of your home comfort system that helps maintain the overall temperature in your home through even air distribution.

In this blog post, the HVAC experts at Penguin Air, Plumbing, and Electrical discuss what an air handler does, along with signs that it’s malfunctioning and impacting your overall comfort.

The Purpose of Air Handlers

The purpose of an air handler is to distribute heated or cooled air throughout your home. They traditionally work in tandem with either a heat pump or an AC system to regulate the circulation of indoor air.

Unlike an air conditioner, an air handler doesn’t directly cool air. Instead, it ensures that your HVAC system provides proper ventilation and temperature control.

How Air Handlers Work

Air handlers have several critical parts, including an evaporator coil, blower motor, and filters, to help distribute air evenly. The evaporator coil removes humidity in the summer and adds heat to your air in the winter, while the blower motor circulates air through your ductwork and filtration system.

By working alongside your heat pump or AC, an air handler can help maintain your desired temperature and improve your indoor air quality.

Signs Your Air Handler Is Malfunctioning

If your air handler isn’t working properly, it’s important to call a professional. Signs you may need repairs include:

  • Inconsistent temperatures: Hot and cold spots in your home indicate that your air handler isn’t distributing air evenly, possibly due to issues with the blower or evaporator coil.
  • Weak airflow: If you don’t feel air coming out of your vents, it may be because your air filters are clogged with dirt and dust.
  • Leaks: Moisture or water in your condensate pan indicates a leak, which can lead to clogs, mold, and water damage.
  • Strange noises: If you hear strange noises, you may have an issue with an internal component, such as the blower motor.
  • Unpleasant odors: If you smell mold, mildew, or a burning smell, you may need to replace the filters or have a professional check for electrical issues.
