What Is an Air Handler?

If you notice that your air handler is leaking water, it could be due to a few reasons. An air handler is essentially the indoor part of your HVAC system, responsible for circulating both cold and warm air throughout your living spaces. The air handler works by drawing in air, cooling or heating it, and then redistributing it back into your home.

Over time, however, the condensation created by the cooling process can cause water to collect and potentially leak from your air handler. This leaves your air conditioning system vulnerable to mold and other unwanted microorganisms, which could negatively impact indoor air quality. If you suspect your air handler is leaking water, it’s always best to consult with an HVAC professional to diagnose and fix the problem before it leads to larger issues.

A Brief Overview of Air Handlers

An air handler is an essential component of an HVAC system that moves air throughout the building. It is responsible for circulating fresh air and regulating temperature, humidity, and air quality. Think of it like the lungs of the building, taking in air and delivering it throughout the structure.

An air handler consists of a blower/fan, heating coils or a cooling coil, a filter, and a control system. The blower/fan pulls in air, which is then conditioned by the heating or cooling coils, filtered for pollutants and allergens, and distributed to individual rooms. An air handler is typically located indoors, either in a closet, attic, or basement, and is connected to the ductwork.

It is crucial to have a well-maintained air handler to ensure efficient energy usage and proper air flow throughout the building.

Why Is My Air Handler Leaking Water?

If you’ve noticed water leaking from your air handler, it’s important to cut the power and call a professional immediately. There are a few reasons why your air handler may be leaking water, including a clogged drain line, a dirty air filter, improper installation, or a malfunctioning condensate pump. Over time, dust and debris can build up in the filter and drain line, causing a blockage that prevents water from draining properly.

This can cause condensation to build up and eventually leak out of the air handler. Additionally, if the system was not installed properly, it can cause leaks and damage. A professional can diagnose the issue and provide solutions to prevent further damage.

Don’t ignore a leaky air handler, as it can lead to mold growth and other issues if left unchecked.
