Whooping Noise

I have a 2005 Acura TSX, and for the past 2 years (almost), it has made a high whoooooop noise when I slow down or am stopped. I have no idea what causes it… It’s kind of sporadic. I’ve taken it in and ask the Acura dealership if there are any updates, but they have no idea what’s going on either. Apparently it’s common with my year/model. We’ve done a revac and recharge and it still continues.

Any ideas?

a revac? You think the dirt on the floormats was making a whooping sound?

I thought that’s what they did to the A/C… I’m clearly wrong about the term used… But they basically cleaned out my A/C system and started from clean.
