Naturally, your system creates condensation. Typically, this condensation leaves your house through the condensate line. If the line becomes backed up, your drip pan will catch the water and the system will shut off once the water has reached a particular level, as long as you have a float switch properly installed. If you do not have a drip pan and float switch, we highly urge you to have those items installed as soon as possible. If the pan is not there, the area that your furnace or air handler is located in, may flood if your condensate line becomes backed up.
Just like with all other things involving water, if it sits long enough you end up with algae. After a while, this algae can build up in the condensate line and block the flow of water. If this happens, there is something you can do but you must act in a timely manner. Ignoring the problem will only lead to larger, more expensive problems. Basically, as soon as you notice it backing up, start the clearing process immediately.
First, shut the power off to your system. The easiest way to do this is to shut the “light switch” off near your system. It only looks like a light switch though, it’s actually the power to your system. For extra safety, you can remove the filter door. This will trip a safety switch which will not allow the system to run. Next, find the drain line access point. They are usually T shaped with a PVC cover. Remove the cover and you’ll find the drain. Pour a mixture of half white vinegar and half warm water into the drain slowly. Let it sit for 30 minutes. Come back with warm water to flush once again.
Hopefully this will resolve your issue but it may not depending on the severity of the situation. Never force anything into your drain. By doing so, you may puncture the line which would cause a much bigger mess and more frustration. If you don’t feel comfortable with the above steps or your drain is still clogged, no problem! Just give us a call at 770-672-6963. We’ll be happy to come out and clear your drain line for you. Some clogs need to be blown out with nitrogen because they’re just that extreme.
