Since I didn't have much work to do, I decided to check my air conditioner for mold formations, which I began to suspect about after I smelled an unpleasant smell during the operation of the system. It turned out that there really is mold on the filter that needs to be serviced every six months.

Mold growth in air conditioning systems can be a common problem, but I took it seriously. I decided to get into cleaning, but I needed a guide that I found on the blog https://www.fortador-usa.com/blog/how-to-get-rid-of-mould-in-air-co.... Professionals share their experience in removing mold in ac unit using various means, and I, following the instructions, solved this problem step by step. First, he took off the lid, took out the filter, cleaned it with the liquid that he prepared about the recipe from the article and treated the surfaces with a steam cleaner, which would surely not only clean but also kill all microorganisms. Everything turned out to be done in less than 1 hour - the result is super. Now I will do checks every few months - I recommend.
