Jul 9, 2020 at 16:18 comment added Krupal Patel I have check with my neighbors. they have little bit of noise but not loud as mine. I was searching online and someone wrote all compressor are not same, even though it is from same manufacturer, some may be louder than other? is it true? sorry I don't know anything about compressor.
Jul 6, 2020 at 22:55 comment added Ed Beal The mounting method really goes back to the type of system in my experience. I normally pad mount straight single speed compressors because there old time technology is a bit noisy, but with gell pads , neoprene isolators or other forms of isolation I have seen these compressors mounted on walls. When it comes to VFD or inverter driven compressors these are usually so quiet it doesn’t matter. A 2-1/2 ton unit on the factory rubber pads I can barely hear right outside my window with the window open.
Jul 6, 2020 at 14:52 comment added Krupal Patel Thank you so much for your answer. it is greatly appreciated. in my previous house which I also bought from the same builder, brand new AC was not making such sound. I am just wondering if this humming noise is normal?? and what could be the definition of normal humming noise vs loud humming noise which is not normal? I am confused because the builder's HVAC technician came and checked it and said this humming noise is normal but I am not completely satisfied with it. please advise me on this humming noise if it is normal or not.
