Noisy air conditioner at a church and many large window units

There were some Carrier units at a church which is unfortunately closed and one of them started up just before I started filming. I couldn't tell which one it was but it was super loud. There were also big window units with huge reciprocating compressors. I'm pretty sure they were Bristols but it was hard to tell.
