Our a/c is so loud I have to turn the TV up all the way. I read on this forum last week ( couldn't find the post) about someone talking about a product from wacko products that is an a/c silencer. I went ahead and order the product despite being kinda pricy. It was very easy to install and to my surprise I would say that it does work very well. I would say that it has made at least a 50% or more less noise. Now we can watch TV without turning up the sound full blast. Just wanted to pass this on to the Heartland family.
