Use A Shop Vac And Water

Next, connect your shop vac hose to the end of your drain line . If the hose connects loosely, you can use a cloth or duct tape to create an airtight seal. Turn the vacuum on.

At the same time, get a gallon jug of water and a funnel. Slowly pour water into the drain line access point near your air handler. The shop vac should suck the water out of your drain line and into your vacuum.

Be careful because if the clog does not loosen, water will back up into your drain line and potentially leak onto the floor.

Pour warm water into the AC drain line access hole near your indoor air handler.

Some newer HVAC systems are actually designed with sensors that warn you that your drain line has a clog letting you fix the problem before it gets any worse.

However, older systems wont have these sensors, so youll need to know what to look for. Signs of clogged AC drain lines are:

  • If the drain pan is full of water, it means that the excess condensation isnt dripping into the pipe. Check the condensate pan when you change your air filters.
  • If your air conditioner wont turn on , it can mean that the drain line is clogged, overflowing, and tripping the float switch. This will turn off your AC and keep it from turning back on.
  • If there is standing water near the air conditioning system, it means that the drain line or drain pan has probably overflowed and is causing water to collect. This can lead to costly repairs, water damage, and mold growth.

None of this sounds good, right? Well, dont worry. Luckily, you can clean your AC drain line with bleach or vinegar to dissolve the clog and remove any bacterial buildup.

    Ac Drain Line Clogged Dont Use Bleach Or Vinegar Until You Read This

    So your AC drain line is clogged and you are trying to figure out what to do next. You’ve come to the right place.

    Being an air conditioning company located in the heart of Central Florida, we are well acquainted with clogged AC drain lines. Our year round high temperatures and high humidity make us prone to higher rates of clogged AC drain lines than just about anywhere else in the country. And our technicians collectively unclog and clean thousands of AC drain lines each year.

    So please trust us when we tell you to put away your bleach and your vinegar.

    Despite it being common for people to recommend using a vinegar or bleach solution to clean your AC drain lines, we’re going to tell you why it’s not a good idea.

    Bleach and Vinegar are Corrosive to metals

    The reason you shouldn’t use bleach or vinegar to clean your AC drain line all boils down to the fact that these chemicals are corrosive to metals. In other words, they literally eat away at metal.

    Why is that a problem you ask?

    They Can Damage Your Evaporator Coil

    The evaporator coil is inside of your indoor air handler. It is normally just inches away from your AC drain line.

    The job of an evaporator coil is to cool your air by removing moisture. The moisture from the evaporator coil then collects in the drain pain and is directed into the drain line and out of your home.

    So if using bleach or vinegar can damage your evaporator coil, what should you do instead?

    Use Water And A Shop Vac

    Once you have checked and cleaned the blockages with your fingers, it is time for some heavy-duty cleaning. Shop vacs and water is a good combo if you are concerned about the condition of your evaporator coils.

    Connect a shop vac hose to the outward drain line. If it doesnt fit tightly, simply attach a duct tape or cloth to make the seal airtight. Next, turn the vacuum on.

    Keep a gallon jug of water and the funnel nearby. Now, pour the water into the access point near the air handler very gently. This way, the shop vac can suck the water, along with any residue, out of the drain line.

    Signs That Your Ac Drain Line Could Be Clogged

    So, youve found your AC drain line, but how do you know if its clogged? Its not always obvious, but weve given a quick breakdown of the common issues that mean theres an issue with the drain line:

    The AC Stops Working

    Most AC units can take over 30 gallons of water from the air inside your home, and this all needs to go somewhere. It can be hazardous to have that much moisture remain within your machine, and most modern AC units have a sensor that detects excess liquid and shuts the conditioner down.

    If your AC stops working, you should check the condenser pan to see if its full, and then see if the water is flowing out of your drain line as it should. You may need to clean it out before you can restart the AC unit.

    Water Dripping Around The Inside Unit

    Most AC units have an interior and exterior unit. If you start to notice moisture around the base of the interior unit, it can mean that theres too much liquid in the machine. The most common cause of this is a blocked drain line, and youll need to clean it immediately.

    The AC Drip Pan Is Full

    The condensation and moisture from your AC first fills a drain pan and then drips down the drain line. If you notice that your drain pan is constantly full or taking longer to empty, it may mean your drain line is clogged. Youll need to clean it to get the water flowing again.

    What Is A Condensate Drain Line

    While your AC unit cools your home, the evaporator coil produces tiny water droplets called condensation. The water drippings fall into the drip pan, and then the water leaves the unit through the condensate drain pipe.


    Do not use diluted bleach to clean your system because the AC unit might expel bleach vapor, which is harmful in high amounts.

    Is Bleach Or Vinegar Better For Your Ac Drain Line

    Most of us hate the odor, but vinegar is safer to use as it is less reactive.

    On the other hand, bleach can eat away at the drain line and damage the cement and glue connecting the cable to the condensation pan and fittings.

    You will also notice that most HVAC professionals favor distilled vinegar over other types of vinegar. Thats because it contains around 95% water and 5% acetic acid. Hence, it can clear up the blockage effectively without causing damage.

    Do not attempt to mix bleach and vinegar if your AC units drain line is still clogged despite pouring vinegar.

    While we all use bleach and vinegar to clean various surfaces, this article on Health Line recommends against it. When combined, these two substances release a chlorine gas that is harmful to your health.
