DIY Tips for Cleaning Your AC’s Condensate Drain

air conditioning service in Wake Forest NCIf the line that your air conditioning unit uses to get rid of all the moisture that it pulls from the air becomes clogged, your air conditioning unit could stop working. A clog in this line can cause the drain pan underneath your AC unit to fill water. Newer air conditioning units are equipped with a sensor in the drain pan which will cause your unit to shut off and keep it from overflowing. However, if your unit is older, you may not know there is a problem with a clogged drain line until the pan overflows and has caused water damage to your home. While you could call an HVAC company to come and clean the line out for you, many homeowners choose to tackle this problem themselves. Here's how to address this common problem on your own.

  1. At the breaker, turn off the power to the thermostat and air conditioning.
  2. Find the location of the drain line outside your home. The most common place for this drain is near the condenser unit. Look for visible signs of clogs around the drain line exit like mud, insect nests, and plants. In some cases, you may not have an exterior drain. Many HVAC units drain into bathroom drains or other parts of the plumbing system in your home.
  3. If the area around your exterior drain exit is clear, you'll need to look for the drain line access point in your home near the indoor air handler. Remove the plug on the drain line and attach the suction hose of a shop vac to the line. A tight connection will be needed in order for the clog to be pulled out.
  4. Should you not have a shop vac available to you, some homeowners have had success using a lint hose attachment that is intended for cleaning out dryer vents to help clear the blockages in the line.
  5. Clogs may occur closer to the exit point, so you may find it beneficial to suction at the exit end of the drain line.
  6. For stubborn clogs, pouring a cup of white vinegar into the access point and allowing it to sit for a few hours can help break up the clog and kill any mold or algae that is present in the line. After letting the vinegar sit, you can try suctioning the clog out or trying to remove it with your lint grabber. Due to the fact that vinegar may harm outdoor plants, you may need to place a bucket under the exterior drain exit to help protect your landscaping.
