Locate the white plastic pipe that leads outside, then check for any blockages like debris or ice. Defrost ice with warm water, not boiling, and use a rod or wire to push through the obstruction. If that doesn't work, call a pro with specialist equipment.
Over time the drain line can become clogged and cause water to back up into your HVAC system, which can shut it down altogether. Follow these steps to check your HVAC system for clogs and remove them. Identify the Issue: When your AC malfunctions, it's crucial to diagnose the problem before considering a replacement.
Flush Condensate Drain Line
The repair cost to have the drain line flushed runs between $75 to $250.
You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit.
All right, so in summary, don't use bleach; use vinegar. That helps with any mildew growth—keeps you running clean. It's not going to actually clean your A/C drain, but it can prevent some backups.
How do I find my AC drain line? Your AC has a condensate drain line running from the indoor to the outdoor unit. You'll find the end of the drain line somewhere near the outdoor unit (usually a copper or white PVC pipe). As for the access point, look for a vertical pipe with a cap near the indoor unit.
Common condensate issues
Common ways to identify if your condensate pipe is blocked are listening for an unusual gurgling sound when the boiler attempts to start, or the boiler may repeatedly 'lock out' or stop working and display an EA code.
Turn off your AC and remove the drain line from underneath by unscrewing the screws on its base. Then attach a hose to it and run water through it for several minutes or until all of the water comes out clean. This will cause water pressure in your drains to increase and push out any debris lodged inside them.
Remember, while some maintenance tasks can be done yourself, others should be left to professionals. In conclusion, it's normal for your AC to drip water outside as it's a byproduct of the cooling and dehumidification process. However, if the unit leaking water is excessive or unusual, this could indicate a problem.
Over time, debris, mold, and algae can build up in these lines, causing clogs and potential damage to your AC unit. The good news is that you can easily tackle this task using a simple and eco-friendly solution: vinegar.
If the air conditioner is not properly draining water, it indicates that there is a leak occurring somewhere else in the system. To address this issue, it is crucial to rely on the expertise of a skilled technician who can first identify the problem among the potential causes.
You'll find a white PVC or copper pipe located near your outdoor unit—this is where the drain line ends. Near your indoor unit, you'll find a vertical PVC pipe with a cap on it, which acts as the access point for the condensate drain.
Effects on Metal and PVC Pipes
While harmless for most metal and PVC pipes, prolonged exposure to the acidic nature of vinegar might corrode certain metals, like copper. PVC pipes, on the other hand, can withstand these substances without damage.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Water and Dish Soap
Dish soap and water, of course! 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.
If the drain line gets blocked, you may experience reduced cooling efficiency, water leakage, frozen coils, Mold and mildew growth, and even a shutdown of your entire air conditioning system.
You can also try pouring a ¼ of a cup of white distilled vinegar (hydrogen peroxide or hot water and a bit of dish soap will also work) down the drain line access and let it sit for 30 minutes. That will help break down the clog and make it easier to vacuum out.
Unclogging Your Condensate Drain Line
The most popular method is using a 50/50 mixture of hot water an vinegar and pouring this down the drain line to clean it out.
