What are central AC drain lines?<\/span><\/h2>\n

Your central AC creates moisture while it cools your home. That moisture gathers on the evaporator coils and drips down into a drain pan below. From there, the water moves into the drain line, which usually leads outside. Drain lines can go up and down or side to side, and they usually connect to your home’s plumbing or empty outside. This setup keeps water from building up in the air handler or under your AC unit.<\/span><\/p>\n

If the drain line gets cracked, clogged, or damaged in any way, water can back up and leak around your air handler. Over time, a clogged or broken line might cause mold to grow, corrode the evaporator coils, or even make the whole system shut down. Swapping out the line keeps water flowing away from your unit properly, helping cut down on mildew and bad smells. Too much moisture in closed-off areas can encourage mold and mildew, which isn’t great for your family’s health. If you spot or sniff out mold near your AC unit, it’s a good idea to first check the drain line for blockages or standing water.\u00a0 Here are some easy signs to keep an eye out for that indicate it’s time for a new drain line:<\/span><\/p>\n
