29 June 2018 - Saloon Aircon Not Cooling

A couple of weeks ago, we have noticed that one of the Saloon aircon units were underperforming. We have informed Princess and requested the aircon supplier to visit onboard to check the system before air and seawater temp start to get warm. Our request has been ignored without any diagnosis with comments like doors and windows must be fully closed, the system must be allowed to cool the area etc.
Recently we have noticed that the unit's performance has further deteriorated. A quick measurement on the outlet ducts of both units revealed the difference. Princess has been reminded again about the issue.

Guest cabin aircon not working

The guest cabin aircon system previously had issues (check this post). It took Princess 47 days to fix the issue which unfortunately resurfaced recently. When we tried to turn on the aircon system of the guest cabin, we noticed that it displayed again the same "LP - Low Pressure" message.
