In Batumi, air conditioners operate almost year-round. Due to humidity, mold, fungi, and bacteria accumulate inside the unit over time, which can cause unpleasant odors and spread through the room with the air. Even if the air conditioner "works normally," it can be very dirty inside. Cleaning includes: deep washing of the indoor unit with disassembly, antibacterial treatment, drainage cleaning, and cleaning of filters and main contaminants. It is recommended to perform cleaning 1 - 2 times a year. I work carefully with my own equipment. Write to me, and we will find a convenient time for you.
