I recorded my air conditioner sound recently. It's one of those thermostat style ones, not the window attachment one. This was recorded right on the vent taking in air as well.

My window air-conditioner on the fan setting. Fan turns on for a few secs and shuts off. Recorded on yeti usb microphone on the stereo setting. Microphone was placed about 6 inches from the unit, right below the top vents where the air comes out. Some very low frequency rumble was attenuated slightly.
Found this air vent on a location shoot. The vent was making a strange chirping noise. . . Like an alien cricket. Recorded with a tascam dr680 and sennheiser mkh-416.
