We are enjoying our new Goodman heat pump and air handler which we had installed this fall.
It has always made a vibration noise that I tracked down to the lineset apparently vibrating against the house where it goes in from outside. If I press on a line while someone is listening inside, it goes away. It seems to be mostly the liquid line, but the suction line might do it too.
So I'm thinking it's a simple matter of getting some foam insulation in there to isolate them. There is some putty around them now. The contractor has not returned my phone call regarding this (he's often slow to respond), and I'm also thinking this should be a simple fix for me to do. I know DIY is not condoned here, but I feel foolish chasing down my contractor and insisting on a service call if I can easily just stuff some foam or something in there.
Any suggestions appreciated! Thanks!
