I had recently relocated into a brand new apartment. It was really weird at first when I required the use of the air conditioning. The air conditioning operated completely fine. It blew out the cooling air that I needed to remain comfortable. I unquestionably never had any issue with that. However, whenever it would kick on it made a really loud banging noise. I had met up with my buddy who lived in the building and she had said that even she could tell whenever I ran it. I unquestionably had to call the service person from the HVAC company about this noise coming from the A/C every time I wanted the air conditioning to operate. The service personnel came over the same morning to examine the system. She had found that there was something amiss with the fan blade. It was causing the fan blade to smack up against the system during startup. So every time the ac turned on, the fan blade would smack something. That is where the exact noise issue was coming from. She said she was going to have to place an order for the section of fan she needed in order to fix the noise. So I was going to have to deal with that banging noise just a little bit longer. She finally got the piece in plus came right over the very same day to fix the issue. Luckily I was not at home at the time. I had some business to take care of that morning. In fact I came home but didn’t even realize she had come for awhile because the air conditioning never made a banging noise again. It was so taxing for me to be able to notice if it was even fixed. The air conditioning plan was so quiet now that I had forgotten all about it.
