I had a new Coleman Mach AC recently installed into my 1987 Toyota Dolphin.

 

It is super loud.  Is this inevitable due to the small coach size?  It seems like most of the noise is from air rushing out of the vents.  Can I adjust the blower speed to just deliver less air?

I tried running the A/C again after getting the vehicle out of storage.  I'm starting to think most of the noise is from the fan motor itself because when the unit runs in "low heat" mode the air really isn't that noisy.  Perhaps some sound-proofing material would help?
