Ayam not sure whether this is normal outdoor AC unit noise.. Just bought it less than 3 weeks ago. I bought two unit, 1hp and 1.5hp. The 1.5hp is noisy. Any sifu can advice whether your outdoor AC is making noises this loud?

That sounds noisy. Even my 1990s Toshiba also just a whooooo wind noise blowing hot air.

When you press in the ODU fan cover gently (spread your palm like starfish), does it quiet down?
Also try pressing down from the top gently (sign of not fastened correctly to the bracket).
Could be poor electrical contact at the MCB (less likely, but u can cycle on and off the MCB a few times at the DB box for the aircon circuit).

i also got the 1.5hp daikin, so far don't have this sound. Better check with daikin after sales service to double make sure.

Hmm I tried but still the same, noisy af .

Time to call them tomorrow to lodge a warranty claim.

sounds like an inverter unit running higher than 100 percent capacity.

if the sound lowers down when it reaches the set temp.......or if you set a higher temp.......it might be normal behavior.

Fuiyoh, super noisy!
It's inverter ka?

My panasonic also make the same loud noise, but the sound become very quite after it reaches the set temperature. I suspect because the outdoor unit is sitting loose on the bracket as my stupid contractor never put any bolt attaching the outdoor unit to the bracket.

Can use felt pads or cut up a used belt to form washer-like feet to insulate the ODU against metal bracket so it doesn't make the metal on metal noise, before attaching bolts to secure it. Bolts also very cheap but still they cut corners.

It's more like they were lazy to put on bolts then saving money to supply bolts. My previous AC installer also so lazy only put 2 bolts on the bracket. This one even worse never put bolts at all. To make it worse, the holes on the ODU weren't aligned with the holes on the bracket, hence I have to study whether trying to align the ODU myself would have effect to the copper connection.

Else, worst case scenario - you can still make another 2 holes accordingly on the bracket if needed (when your drill arrives)

Good idea! TBH I have never used a drill before in my life. The only "power tools" I have ever use is a mini drill with screw driver attachment. I have practice first before attempting that.

Yup metal will need HSS bits. U can practise on old tin can. Mark the center dot, punch a depression using nail n hammer, then the drill bit won't runaway.

Happy DIY!
Don't end up messing things up...haha

you can use self drilling screw if you dont have a drill.

use metal washer and rubber washer accordingly. and dont overtighten.

good luck DIY..
just don't do wrongly.... ended up extra cost

Ya inverter mah so noisy useless shit

still under warranty can call their hotline, they will send technician to check.

Ya I already raised a ticket to them, maybe next week only they arrange to come

you have 2 ODU on that wall ya or ??
