cooked Posted April 29, 2016 Share Posted April 29, 2016 I tried googling this but found no solution. We had a service done in January and now one unit has started to make a noise, slightly louder than usual, that sounds like a gusty wind, coming from the internal blower. The filters are clean, anything I can do before I call the A?C man? Thanks Link to comment Share on other sites More sharing options...
trd Posted April 29, 2016 Share Posted April 29, 2016 It means it's time for an internal clean. The gusty sound is a dead giveaway that there's dust inside. I get mine cleaned every three months or when the airflow starts to sound irregular as you describe. Daikin air cons seem to be very susceptible to this gusty noise.

Crossy Posted April 29, 2016 Share Posted April 29, 2016 Our bedroom Samsung whistles when the filters start getting clogged, not unique to Daikin. Link to comment Share on other sites More sharing options...
trd Posted April 29, 2016 Share Posted April 29, 2016 Our bedroom Samsung whistles when the filters start getting clogged, not unique to Daikin.That's the Samsung whistle. The Daikin gush is quite different and is not caused by clogged filters. An engineer told me that the design of Daikin's rotor fan in the evaporator of a particular series of model causes these whooshing sounds when dust gets attached to the plastic lattice framework. On the other hand my Mitsubishi could get packed with dust and it would still purr like a kitten. In the twenty years I've been buying aircons here, I would now only ever buy Mitsubishi. I was once told by another Thai engineer that the Rolls Royce of aircons was made by Fujitsu, but I haven't had a chance to verify that. Link to comment Share on other sites More sharing options...
ammagic Posted April 29, 2016 Share Posted April 29, 2016 I have a Panasonic - so quiet you wouldn't even know it's on, a bit pricey though. Just bought it so hoping for a very long life! Link to comment Share on other sites More sharing options...
passingas Posted May 1, 2016 Share Posted May 1, 2016 Glad to hear that about Mitsubishi...just bought one this week! Not an inverter model, but in the lowest fan speed, it can't be heard at all. pg Link to comment Share on other sites More sharing options...
Monkey Fish Posted May 2, 2016 Share Posted May 2, 2016 I have 10 yr. old Daikin air-cons and have also experienced the whooshing noise. Cleaning takes care of it . . . for a while. You might think of the whooshing noise as a warning that the condensation outlet is near to clogging and it will start dripping water soon. My units also got a louder and louder "whine" as the motors aged. Replacing the motor fixed it. My guy charged the price of the motor (1,800 baht two years ago, 2,100 baht two weeks ago) plus a 500 baht installation fee. Link to comment Share on other sites More sharing options...
