I just got a new wall split air conditioner (KFR-50GW – 18000 btu) installled and i’ve noticed that it runs much louder than it supposed to. On my iPhone it says 69DB at LOW (was supposed to be max 45 at HIGH). I know it’s a cheap brand and didn’t expect it to last 15 years, but it’s just way too loud. Is that normal behaviour with cheap brands?
Also, they installed a water drainage pipe to bring water to the ground, but i see a lot of water drops on my balcony. I will call them back, but i’m sure they’ll try to convince me it’s perfectly normal.
