Signs Your A/C Drain Line is Clogged

clogged A/C drain lineYour air conditioner pulls moisture from the indoor air as it cools your home. The moisture cools and drips into a condensate pan. It then travels through the drain line, which is a pipe that runs from the indoor evaporator coil to the outside of your home. Without proper maintenance, the drain line can clog with dust or mold and even make your unit shut down.

Here are the clues that indicate you may have a clogged A/C drain pipe.

Standing Water

This is the most obvious symptom of a clogged drain line. A problem with the pipe can make water back up, resulting in standing water around your air conditioner. If there’s water dripping from your unit, be sure to contact an HVAC professional.

Moldy Odor

A moldy smell could also indicate a drain pipe issue. If you can smell a moldy scent, check your A/C unit’s drip pan. If it has a musty odor or visible mold, then that’s a clear sign of a problem that you should address quickly. Otherwise, the mold may spread and cause massive damage.

Full Condensate Pan

It’s important for you to check your condensate pan periodically. If it’s always full, this could be a sign of a problem with your drain line. You should have the issue fixed immediately to prevent mold growth.

Water Damage

Excess backup of water due to a clogged drain line can make your house exhibit signs of water damage, such as:

  • soggy walls, ceilings, or floors
  • dark streaks on ceilings and walls
  • musty smells
  • buckling walls and floors

If you experience an issue with your drain pipe, you need to act fast to prevent the spread of mold growth or water damage. Remember, getting a maintenance plan with a reputable HVAC contractor will go a long way to helping you avoid having a clogged A/C drain pipe or any other air conditioning problems.
