What's an AC Air Handler?

You know the air in your home feels nice, but do you know exactly how it got that way? It was the doing of your HVAC unit, of course, but a lot more goes into conditioning your home’s air to an ideal temperature than you may have thought.

Your HVAC unit is made up of several components that work together to keep you comfortable in your home. One of these components, which play a quite significant role, is the AC air handler. Knowing how your air handler works in conjunction with the other parts of your HVAC unit can help you maintain a more efficient system and avoid costly repairs. Here’s everything you need to know about your AC air handler.

What Does an Air Handler Do?

An air handler regulates and circulates air within an HVAC system. Air handlers are usually composed of a blower, heating and cooling elements, filter racks, dampers and other components. They are connected to a system of ducts that distribute conditioned air throughout a building, and then return it to the handler. The air handler is also responsible for determining whether the air cycling through your HVAC unit is warmer or cooler than the outside air.

What Problems Can Occur With Air Handlers?

As with any appliance, you HVAC unit may encounter the occasional problem that keeps it from running efficiently. Here some of the most common issues air handlers tend to experience.

  • Leaks – The Florida heat can put added stress on your HVAC unit, meaning your air handler may experience problems resulting from overexertion. When it’s especially hot outside, condensation may build up in your air handler, causing a leak. The water that leaks out accumulates in a drain pan located directly below the air handler. Excessive water pooling around your drain pan is an issue not to be overlooked, because it could cause algae to build up and clog your drain lines.
  • Fan Unit Issues – The air handler works in unison with a fan unit to condition the air that circulates throughout your home. While the air handler regulates and circulates air, the fan unit helps to blow the air through ducts that reach into the different areas of your home. As with the rest of your system, fan units have to work harder to help deliver cool air when it’s hot outside. This extra workload can sometimes cause the fan to break. If you notice your home isn’t as cool as it should be, check the air handler and the fan unit to see if that’s the source, or call a technician to diagnose the issue.
