There are a few reasons why this problem may occur. Dust and debris may enter your condensate line near your air handler over time and eventually plug up the line, blocking the flow of water that needs to drain as your A/C creates condensation on the evaporator coil. In addition, if your condensate line was improperly installed (not at a steep enough angle), debris may also build up and create a blockage throughout the line. The main thing is to keep your condensate drain line free of debris and mold. If you can stay on top of this issue with regular maintenance, a full A/C repair need not occur.
There are a few options when it comes to cleaning your condensate drain that should work. Simply removing debris manually or with a small plumbing snake may be all you need to do. However, remember that since the pipe is likely plastic, you should attempt to do this gently to avoid unnecessary leaking or breakage. Some models even have cleanout ports that are easily cleaned with soap and water. If your drain has a heavy clog that has been building up for some time, you may need to resort to blowing out the clog either with compressed air or a vacuum pump. If this is necessary, you may want to contact an HVAC professional.
