I avoided installing an A/C in my condo for a couple years because I felt there was no need to endure the noise that comes with it.
While some people find it soothing, I wouldn’t say I liked it at all. I lived in an area where temperatures were not extreme, & that my condo was fully insulated made it easy to live without heating and cooling. All I needed was a wonderful gas furnace to help keep me sizzling from December through March. I did not struggle with cooling my condo since it was generally nice to be indoors even when the sun’s heat was scorching the nearby earth. However, all these changed when a task move necessitated my move. I had to adjust to living in a new place where weather patterns are now erratic, & it could get too overheated or too arctic. Unfortunately, my condo was not well insulated since it was an old college model. My only really good way to deal with it is to get a Heating & A/C unit, which was already installed. My experience with the buzzing noises a/cs make was not good, & I knew I had to find a solution straightaway. I had heard about such adjustments & needed an expert to do to get sound reduction methods on the air conditioning system device in my house. The Heating & A/C worker said I should get lining for the interior of the air duct using melamine foam. It would serve as an absorber that would almost eliminate my ability to hear the noise & at the same time would be good insulation. I was able to sleep well again because I could hardly hear the HVAC buzzes.
