Why does my AC drain line keep clogging?
Because of warm air that blows over the cold coil of the HVAC, the drain pipe can get pretty humid; and along with the condensate traveling through the pipe, these can lead to clogged pipes. If your air conditioner has a built-in filter, you can remove the filter and clean the air conditioning system.
However, if you don’t have a filter on your AC system, then you will need to use a vacuum cleaner to clean it. Vacuum cleaners can be purchased at any home improvement store. You can also use an air purifier, but be sure to follow the manufacturer’s instructions for proper use.
Is bleach or vinegar better for 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. It is safe to use vinegar on carpets and clothing, but spilling bleach can ruin your carpet or clothing.
If you do not have access to a vinegar solution, you can also use a drain cleaner to clean your drain lines. You can find a variety of drain cleaners at your local hardware or home improvement store.
Should AC drain line have water in it?
