Hi all and thanks in advance for all the time and help.
I read the forum rules and stickies and I am glad to report I have been helping
support many an air conditioner repair man and engineers due to the following problem.
I, roughly 6 years ago, bought an office in Miami Beach. The unit is next to a HVAC closet and there has always been noise one way or another.
First, the noise was from the air returning through my unit coming through a return above my desk and now it seems to be from the actual air handler blowing air.
This issue has been going on for over 6+ years and the condo board has hired many a professional to check it out. I am going to use this thread to post as much information that is needed for you guys to see if everyone is missing something stupid.
The next plan of action the engineer is going to do is put the unit on some kind of vibration pad. Are some pads better than others? What would you guys suggest?
I found the manual for the unit online and I presume that pad in the diagram is what the engineer is talking about
Here are some pics that might help:
One of the pics shows what I think is a 'flex duct connector.' Is there anyway to enhance the noise dampening ability of that connector? Add another or upgrade to a better one?
As I am sure you guys can tell when it comes to air conditioning I am a neophyte but I am grateful for a site like this.
If there is any additional information you guys need please just ask. I will be adding anything else I can think of to this thread to make the picture as clear as possible.
Once again, thanks in advance!
