A drain clog caused my a/c to shut off

Recently, I came home to quite a surprise.

It seemed that my heating and cooling system was not working at all, as it must have shut off at one point while I was at labor during the day. I could not figure out for the life of me what the problem was. The control unit seemed to be in wonderful working order, it’s just that the Heating and Air Conditioning system refused to turn on. I checked the air filter and it wasn’t particularly all that dirty yet, as I had changed it just a couple weeks prior. What sort of problem can my cooling system be dealing with? I particularly hoped that it wasn’t a huge deal. When I realized that I wasn’t going to be able to figure it out on my own, I went ahead and called out a heating and Air Conditioning professional. Thankfully, the professional came that same day and he managed to find the problem quickly. He discovered that the drain line was all plugged up and it was causing the system to just automatically shut off and not function. I never encountered this problem before and he explained that every now and then I need to pour a cleaning solution such as colorless vinegar down through the drain line to help keep it free of clogs. This would stop the problem from occurring in the future. He went ahead and worked on all the issues with the cooling system and I promised him that I would do this in the future to prevent the system from shutting down.
