How to Keep AC Drain Lines Clear
You rely on your air conditioning system during the hot summer to keep your home comfortable. However, a clogged AC drain line can lead to various problems, including water damage, mold growth, and reduced AC performance. Fortunately, there are several steps you can take to keep your AC drain lines clear and functioning properly.
What is an AC drain line?
Let’s quickly go over what it is and what it does before talking about how to keep your AC drain line clear. The AC drain line is a small pipe that runs from your air conditioner’s evaporator coil to the outside of your home. Its purpose is to remove condensation that forms on the coil during the cooling process. Without a functioning drain line, this moisture would build up and eventually cause water damage or other problems.
Why do AC drain lines get clogged?
AC drain lines can become clogged for a variety of reasons, including:
- Dirt and debris buildup: Over time, dirt, dust, and other debris can accumulate in the drain line, causing clogs.
- Algae and mold growth: The dark, damp environment inside the drain line can be a breeding ground for algae and mold, which can quickly clog the line.
- Poor installation: If the drain line is not installed properly, it may be more prone to clogging.

Now that we know why AC drain lines get clogged, let’s discuss some steps you can take to prevent clogs and keep your drain line clear.
Change Your Air Filter Regularly
One of the simplest and most effective ways to prevent AC drain line clogs is to change your air filter regularly. A dirty air filter can reduce airflow and increase moisture buildup, contributing to drain line clogs. Aim to change your air filter every 1–3 months, depending on your usage and type of filter.
Clean the AC Drain Lines
Cleaning the AC drain line is another important step in preventing clogs. To do this, locate the drain line outside your home (it will be a PVC pipe near your outdoor unit) and gently flush it out with water. You can use a garden hose or a special attachment designed for this purpose. Be careful not to use too much pressure, which could damage the line. If you notice any visible clogs, you may need to use a pipe cleaner or call in a professional to clear the line.
Use Algaecide Tablets
As we mentioned earlier, algae and mold growth can quickly clog an AC drain line. To prevent this, you can use algaecide tablets, which are small tablets that dissolve slowly and release chemicals that prevent algae and mold growth. Simply drop one or two tablets into the drain pan monthly during the cooling season.
FAQs
Q: How do I know if my AC drain line is clogged?
A: Some signs of a clogged AC drain line include water leaking from your indoor unit, musty odors, and reduced AC performance. If you see any of these signs, you should check your drain line and clean it if necessary.
Q: Can I use vinegar or bleach to clean my AC drain line?
A: While vinegar or bleach can effectively kill mold and algae, they can also harm your AC drain line if used improperly. Vinegar and bleach are both acidic and using too much of either substance or leaving it in the drain line for too long can damage the PVC material of the line for use in AC drain lines. Instead, we suggest using an algaecide product that is made to be used in air conditioner drain lines.
Q: Do I need a professional to clean my AC drain line?
A: In most cases, you can clean your AC drain line yourself using the steps we outlined above. However, if you’re uncomfortable doing so or notice any major clogs or other issues, it’s best to call a professional HVAC technician to inspect and repair your system.
Q: How often should I clean my AC drain line?
A: We recommend cleaning your AC drain line at least once per year, ideally before the start of the cooling season. However, if you live in a particularly humid or dusty area, you may need to clean it more often.
Q: Can a clogged AC drain line cause other problems besides water damage?
A: Yes, a clogged AC drain line can lead to reduced AC performance, as well as increased energy bills and mold growth. It can also create an environment for insects and other pests to thrive.
In conclusion, keeping your AC drain line clear is important to maintaining your air conditioning system and preventing water damage and other issues. By following these simple steps and being mindful of signs of a clogged drain line, you can keep your home cool and comfortable all summer long.
