We spent a lot of time this week servicing all the air conditioners and fixing some of our refrigeration systems. We also had the ship’s black water pumped out. The ship has around 14 Air conditioners. For most of them we just need to check them out and clean the filters. Unfortunately we had 8 that were getting cover in mold. The mold grows in the inside of the air conditioner unit and it can get pretty thick. This can actually put extra wear on the AC and cause it to run less efficiently. This mold can also have a negative impact on the air quality of the ship. Cleaning them can be a little tricky. We have to partially disassemble the AC to get to all the parts that need cleaning this process can take up to 2 hours per unit. So it took up alot of our time this week, but we got them all cleaned and checked out.
