  • How to Unclog an AC Drain Line with an Air Compressor


    Regularly cleaning your AC drain line can increase the efficiency of your air conditioner and will also prevent the buildup of mold and algae —  which can cause not only humidity but musty odors and water damage too. But while scheduling a maintenance appointment with Energy Air will ensure that a technician unclogs your AC drain line properly, many homeowners ask us if they can use compressed air to unclog their drain pipe.

    We recommend having your air conditioning system serviced by a professional to prevent damage, but if you’re looking to do the job yourself, please be sure to follow these guidelines to unclog your AC drain pipe safely.

    Examine the Clog

    If your air conditioner’s drain line is clogged, then there is a good chance that compressed air can take care of the problem. But first, examine the extent of the clog by doing the following:

    Step 1. Turn off the HVAC system.

    Step 2. Locate the system’s cleaning port.

    Step 3. Remove cleaning port cap to access the clog.

    Once you can see the clog, there are numerous ways to take action before using an air compressor.

    Safer Methods to Consider Before Using Compressed Air

    We recommend having a licensed, professional technician service your AC system. However, if want to do the job yourself, make sure to follow these directions.

    Removing Manually: Depending on the extent of the blockage, you can try to remove the clog manually. Be cautious and avoid pushing the clog deeper into the pipe. You can use water to rinse out any debris that breaks off from the blockage.

    Cleaning Solution: If the problem persists, experts at Energy Air recommend pouring a cleaning solution down the PVC drain line to clear it out.

    Wet/Dry Vacuum: If you’re still dealing with a clogged drain after pouring solution down the PVC, try using a wet/dry vacuum to remove the solution before using an air compressor. A wet/dry vacuum is the safer option when deciding between the two, but if your AC drain pipe needs extra maintenance, an air compressor should solve the problem.

    Unclogging an AC Drain with an Air Compressor

    If none of the above methods worked, try following these steps to unclog your AC drain using compressed air:

    Step 1. Go back to the cleaning port of the air handler unit and place the air compressor at the center of the pipe, making sure to not direct air towards the sides of the PVC pipe. *CAUTION: damage may occur when forcing air through the pipe.*

    Step 2. After clearing the blockage, you can test the drain pipe by pouring cleaning solution or water down the line again to see if it runs freely.

    Step 3. Replace the port cap and turn the system back on.

    If there is still blockage after this step, schedule an appointment with a professional technician.
