Starts under load makes boom sound

by sumi
(chennai)

When this unit starts, my wall shakes (wall is 24" away and brick). It makes a boom sound and then starts up. The installation was made on this unit only 3 months ago and I have had the installer come out to correct the problem twice. He has checked the refrigerant level/pressure and advised they are normal or slightly below. This unit comes with a "hard start componient". Factory representative due out in a couple days but want to find out if this is a common problem with this type of unit.

I recently had A York unit installed and when the outdoor portion of the unit starts, I have a thump sound. It seems to be on the inside wall right next to where the unit is located outside and the freon line enters the house to go to the attic portion.
