Forestchill Anti Vibration Rubber Pads, 4" X 4" X 3/4" Heavy Duty Waffle Vibration Isolation Pad for HVAC, Air Compressor, Washer and Dryer, Air Conditioner Units, 4 Pack

This was just what we needed to stop one of our outdoor units from making fan noise. Very good product!

We recently moved into a rental house and the HVAC sits on a concrete slab right outside the master bedroom wall. When it was on, the bedroom was so loud and the wall literally vibrated. After a week of awful sleep, I ordered these thinking they wouldn't do much but we're worth a shot. Once installed, they cut down on the overall noise in our room by nearly 100%, and the wall doesn't vibrate anymore!

Seems expensive for 4 rubber pads but they worked! We mounted our water pressure pump on these pads and replaced rigid tube connections with flex lunes and the combined noise reduction was something like 90%. Should have done the changes months ago.

Excellent Product! These Anti Vibration Pads helped to reduce the loud vibration sound from my neighbor's Lennox AC compressor.

It keeps the couch from sliding . Very sticky to wooden floors . Plus primarily I got this to prevent my bass shaker vibrations from going to the floor and the wall . So did a great job .

Used them to reduce the heat pump vibrations. Also used them under the washer and dryer. Easy to trim and work very well.

smells pretty bad..

I bought both these and the "blue striped" units of another manufacture and after squeezing both these were an immediate yes as they were much softer, compressable, compliant but still firm. In fairness I haven't tested the blue strip units and they may have the same effect. The reduction of vibration and noise with these was amazing. This was a 5 minute install and I'm stunned that HVAC installers do not use these as SOP.
