A puddle of water on the ground near your air conditioner is one of the first and most obvious signs that your drain line is stopped up. A clogged AC drain line is no joke because it can cause extensive water damage to your home, including mold and weakening your structural foundation.
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.
If you hear sloshing water sounds from behind your car's dashboard, chances are your AC drain line/pipe is clogged with debris. The sloshing noise may be especially noticeable when making turns as well as having a damp floorboard.
Average Unclog AC Drain Line Cost
Typical unclog ac drain line costs can range anywhere from $75-$250.
If the drain line is clogged, your AC won't be able to cool your home effectively. Ineffective cooling increases humidity levels, and you'll experience warmer temperatures. There's water pooling around your indoor AC unit. As warm air passes over your AC's evaporator coils, condensation naturally occurs.
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.
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.
AC is Producing Warm Air
One of the surefire signs of a clogged refrigerant line is if you notice the AC producing warm air when you expect cold air. The warm air is caused by a problem with the proper circulation of the refrigerant fluid, which is instrumental in cooling the air.
The repair cost to have the drain line flushed runs between $75 to $250.
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.
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.
All you have to do is pour 1 cup or baking soda down your drain and then follow it with 1 cup of vinegar. After your mixture is in the drain, seal the top of the drain and wait for about an hour so your concoction can start breaking down any clogs. After about an hour, rinse your drain a few times with boiling water.
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.
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.
How Often Do I Need to Change Out My Air Filter? Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
A clogged condensate drain line will trap water in your air conditioner. As a result, the evaporator coil will eventually turn to ice. The moisture in the drain line can also freeze, which will cause your air conditioner to turn off. But before it does, it'll likely suffer some damage.
You Hear a Gurgling Sound When Water is Flowing
The most prominent sign that your pipes are clogged is a reduced flow rate. Whether it is your shower pipe, faucet, or drain if you see that the water does not flow as fast as it should then you're most probably dealing with some sort of blockage in the pipes.
It's always recommended that you get your boiler serviced on an annual basis to identify any potential issues before they become more serious. Vaillant's annual boiler service includes a rigorous 12-point inspection, including checking and cleaning the condensate trap.
The easiest way to tell that your drain line is clogged is if you see water dripping out of the air handler, or you have standing water on the floor near the unit. If your air conditioner won't turn on, you should also open up the access door on the air handler to see if there is standing water in the drain pan.
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.
It is normal to find water on the drip pan, provided that water is able to smoothly flow out of it through the line. A problem arises if water accumulates in the drip pan, and overflows. That signals your drain is plugged up. If you don't remedy this problem, the water will overflow uncontrollably.
