Hey there, I am not sure that I am in the correct forum but I will start here.
I live on the top floor of a 3 story apartment and the air conditioning units are on the roof top. When my neighbors below air conditioners come on, I get this loud roar, like an airplane sound in my apartment. As soon as their units shut off, my unit jolts and there is a rumbling sound in my apartment.
I thought that the noise was coming from my hot water heater room and maintenance came cover and said that the noise was coming from the units on the roof top. Also, they discovered that there is a pipe coming down from the roof top to vent the hot water room and you can look up and see daylight. Of course, the top is made in such a way that birds or such can not come in.
The noise is just so loud from the units and I'd like to know what can be done to help alleviate it. Can they adjust anything on the unit to lessen the noise? It is really loud at night and is not a nice noise; rather, a rough one.
Any advice will be appreciated.
