Hi! New construction - we have a Coleman heat pump system. No idea of size. Problem is the ceiling grill for the air return makes a lot of noise. Part of it is a vibration - it gets a bit quieter when I put my hand on the grill. Noise goes away completely if I remove the grill. HVAC installer suggested a grill/filter combination - would this eliminate the noise?

richman, I'd suggest asking the installation contractor to fix the problem with what ever solution he is willing to provide at his expense and that which is acceptable to you aesthetically.
