Elephant snot, also known as drain snot, is the nickname often given to the thick, slimy buildup of zoogloea bacteria that can form inside your air conditioner’s condensate drain line. Over time, this gunky mixture of dust, dirt, algae, and other debris collects in the drain pan and line, creating a sticky mess that resembles—you guessed it—snot.
While it might sound humorous, the problem is anything but. If left untreated, this slime can clog the condensate drain line, preventing proper water drainage. When that happens, water can back up into your system, overflow the pan, and potentially cause serious water damage to your ceilings, walls, or flooring. Even worse, standing water can encourage mold growth, creating both health risks and expensive repair bills.
That’s why REGULAR MAINTENANCE of your HVAC system—especially cleaning and clearing the condensate drain line—is so important. By staying ahead of elephant snot buildup, you can protect your system’s efficiency, avoid unexpected breakdowns, and prevent costly damage to your home.
