These units are located at a commercial building in Cedar Rapids, Iowa. These are the first Carrier TECH2000 silencer system units I’ve ever filmed and seen in person! These units are very rare around especially here in Iowa. There were also 3 newer Rheem air conditioners which I think replaced older Carriers just like them. One of the Carrier TECH2000s also had a loud and odd shutdown noise too. I also plan to try for startups here this spring and summer! Recorded April 11, 2024.
