What is the proper way to maintain the drain line on my AC

What is the proper way to maintain the drain line on my ACOne of the most common issues that a homeowner will face with their air conditioning system is a clogged drain line. Although a technician can certainly help you with this issue, it is something that you can do easily without any special tools. Furthermore, if you properly maintain your system the drain line will not get clogged up in the first place. Simple maintenance is only needed about two times each year and will virtually prevent this problem from even happening.

Over time a sludge can form in the bottom of the drain line. As tiny particles move through the system they will sometimes settle and begin to form a clog. As more and more particles build up eventually it will clog the system and cause water to back up into the drain pan of the air conditioner. If this problem goes unresolved the pan will fill with water and eventually overflow into the house. As you can imagine, this is usually when the problem is first noticed.

Once you realize that you have water overflowing into the drain pan you should use your thermostat to shut off your system. You then will need to remove the panel off the inside unit that covers the evaporator coil. Now you should be able to see the drain pan and notice if it is full of water. If the pan is full then you know you have a clog in your drain line. Now empty the water in the pan and place a towel in it to absorb any additional water.

Locate Your Drain Line Is Easy Using The Following Steps

Locate where the condensate pipe exits your home. This will normally be near the copper lines that connect to the outdoor unit. Nearby you should see a plastic pipe that is about an inch in diameter. If you are unable to find it you may need to dig a small hole to locate it. If the pipe is underground then you should clean out the pipe and add an elbow so that it no longer ends beneath the surface of the dirt.

There should be a ninety-degree elbow on the end of the condensate pipe. Remove the elbow as this is generally where the clog will be. If you own a wet/dry vacuum you can use it to suck out any debris from the pipe and you should see the water moving freely. If this still does not free the clog you can use the pressure from a hose to help dislodge it. Make sure you only put about a seconds worth of water down because the water will flow back into the drain pan.

If you want to keep your drain completely free of clogs all you need to do is pour about a half gallon of water down the drain line once or twice a year. The water will flow into the drain and will remove any particles from the system.
