How do you unstop your evaporator drain line?

To unclog your evaporator drain line, first, turn off your air conditioning unit for safety. Locate the drain line, usually a PVC pipe, and use a wet/dry vacuum to suck out any blockage from the exterior opening. Alternatively, you can gently flush the line with a mixture of vinegar and water to dissolve any buildup. If the clog persists, consider using a plumber's snake or calling a professional for assistance.
