- Pour about 1 cup of distilled vinegar or a mixture of bleach and water (1:1 ratio) into the drain line. This will help eliminate mold and algae. - Let it sit for at least 30 minutes. Rinse the Line: After letting the vinegar or bleach solution sit, flush the line with water.
That is a great idea. Shut the air handler down. Pour 1-2 cups of bleach down the right side. Let it sit for 5 minutes or so. Flush with short amounts (2 cups) of warm water. The idea is to flush the bleach and slime out. Several shots of warm water will dilute the bleach and flush it.
Pour Vinegar or Cleaner: - If the vacuum method doesn't work, pour a cup of vinegar or a specialized A/C drain line cleaner into the drain line. - If using vinegar, let it sit for about 30 minutes to help dissolve any buildup. Flush with Water: - After the vinegar has sat, flush the line with water.
Before you panic, rest assured that white slime isn't uncommon. It's a biofilm composed mainly of bacteria called Zooglea. Zooglea forms a protective layer around itself, thriving in the dark, damp environment of your AC's drain pan.
Water and Dish Soap
Use a mixture of both to clean your AC drain line. The dish soap will help to break down the dirt and debris, while the water will flush it away. To use this method, mix a quart of water and a teaspoon of dish soap. Next, pour the mixture into the drain line and allow it to sit for several hours.
Ensure that the solution reaches as far as possible down the line. Let it sit for about 30 minutes to allow the vinegar to break down any buildup. Flush the Drain Line.
Vinegar or hydrogen peroxide
This can help break down the clog, making it easier to pass on its own. After the 30 minutes is up, flush the drain with water to ensure everything is flowing as it should.
Begin by pouring up to a whole box of baking soda down the drain, depending on the severity of the slime. Then pour in the vinegar, up to half a bottle. You should hear or see the fizzing. Let it react for about five minutes, then slowly pour the boiling water down the drain.
If your air conditioner has recurring drain line issues, chances are the cause is white slime. White slime buildup has become a common problem plaguing HVAC systems in recent years. This gelatinous substance lurks in air handlers, clogs drain lines, and causes AC malfunctions.
Some suggest you can clean drains using baking soda and vinegar. Pouring one cup of baking soda and a combination of one cup of water and one cup of vinegar may be beneficial.
You can use a wet/dry vacuum to remove the slime and other debris, and you can finish the job by flushing the line with a cleaning solution. Cleaning or replacing your AC filters regularly and having a pro clean your evaporator coils may stop AC drain slime from happening.
Many HVAC professionals suggest that you avoid using harsh chemicals such as Drano to unclog the block.
It will eradicate mold colonies from your air conditioning system without adversely affecting its performance, structure, or lifespan. Simply mix one cup of white vinegar with a gallon of warm water and spray the solution on the mold.
To unclog an AC drain line, turn off the power to the unit. Locate the drain line and use a wet/dry vacuum to suck out the clog. Flush the line with water using a garden hose or cup of water. Check and clean the drain pan under the indoor unit.
Cleaning AC Drain Line
We recommend using vinegar instead of a bleach solution because bleach can cause corrosion if you have copper tubing in your AC's drain line. In addition, spilling bleach can ruin your carpet or clothing, whereas vinegar does not harm; it just leaves an odor.
Due to its highly acidic nature, apple cider vinegar is self-preserving and doesn't ever really go bad. However, when you buy a bottle at the store, you'll still find an expiration date printed on the label. This is because the FDA requires manufacturers to do so.
Many times, we can clear these types of lines with cutters and cables, but due to the liquid consistency of sludge, sometimes it requires us to use a hydro-jetter (high pressure water machine) to clear.
Repeating the vinegar cleaning process once every month will keep your AC drain line in great condition. The cleaning process is exceptionally effective at removing unwanted bacteria and fungi, allowing your AC to run efficiently. Call (702) 944-8838 Today or Book Online for Heating and Cooling Service!
Drain Line Material
Chlorine bleach can quickly eat away at not only the line but the glue and cement joining the line to the fittings and the condensation pan. If your drain line is PVC, stick to white distilled vinegar for clearing clogs and debris, particularly during winter.
If you have a very stubborn clog that doesn't come out with a shop vac and water, then you can try using a drain snake. Push the drain snake down into the drain line access near the air handler. Make sure the that the drain snake does not go towards your air handler or you could potentially damage the evaporator coil.
Using Bleach in Your AC Drain
Be sure to use a minimum of 2 cups once or twice per year. Be advised, however, that some newer units no longer recommend bleach or vinegar due to oxidation/degradation concerns. In these cases, boiling water is recommended.
