booksntoys 0 Report post Posted January 14, 2011 Actually Panasonic technicians also say same thing, their machine are like that one. If u explain the sound to them, everytime they came say don't hv but Gain City supervisor can hear leh. But Gain City supervisor finally manage to persuade them to change a new condenser unit for us because the supervisor say can hear the noise very clearly in the morning not to mention the quiet night. And our case already dragged on for 4 months plus and we as customer got no choice to abandon masterbedroom & sleep in common room. The supervisor say it is compressor faulty. If after change still same problems, then Gain City will find other ways to help solve our problems. They changed a new compressor for you? WOW! How nice! Now, I just need ppl with inverters to tell me that their compressors are SILENT. Sharp ppl said that all inverters have noise (accelarating audible humming noise even windows closed in the afternoon). If no noise = not inverters!! So far, our main problem is when all 3 air-con are switched on....wah... humming noise really audible & obvious. Share this post Link to post Share on other sites

So far, our main problem is when all 3 air-con are switched on....wah... humming noise really audible & obvious. Yes, panasonic had agreed to change a brand new condenser unit for us. Now still under processing & waiting for Gain City to make the necessary arrangements to install it. According to Gain City supervisor, he say the sound come from the compressor so it will transmit thru pipe and it is classified as second grade of noise. There is 1st grade of noise whereby like bees busy humming sound. Also i want to ask if you did re-use your old pipings or newly installed pipings? One for the forumers mention for inverter is quiet & no humming sound at all after closing the window. He mention for non-inverter one will got sound problems. Or maybe is it only Sharp inverter are noisy? Edited January 15, 2011 by whitefantasy Share this post Link to post Share on other sites
