Roof Air Conditioner Vibrations Through Walls

I must say the furnace so far has been so quiet that we don t know when it is on.

Roof air conditioner vibrations through walls.

This installation required running pipes through the roof because the air conditioner was located in a large living room that had cathedral ceilings. Metal a c wall bracket mount. It is present anytime a ac unit on the roof turns on. I live in an apartment building and they recently installed a new motor on the roof for the hvac system that now vibrates when it s running.

Vibrations caused by a roof mounted air conditioning unit can be very annoying and they may give you the impression that the entire building is about to topple over. It vibrates through my bed and has been keeping me up and waking me up the past 2 months. Previously i had just a box spring without actual springs in it with the mattress on top. It is a low background noise coming through the wall from the ac cables that come from the ac fans and course down through the condo walls.

The system is off the ground allowing additional air flow and a reduced chance of rusting. You will witness noise when the unit is off as air will be flowing through it therefore causing some sound. These cables or condensers or whatever they are are wrapped but still vibrate to the touch up on the roof as they go down through the condo. The two external walls were not able to facilitate the split system so it was positioned on the wall which backed onto the pitched roof at the back of the house.

There have been numerous complaints about vibrations through walls. Commercial chillers and cooling towers noise reduction are two of the primary sources of low frequency sound that causes internal damage from continuous shaking. There can be several reasons for these vibrations while the common problem can be overcome by fixing vibration pads to buffer the noise. Air conditioner noise reduction is easy to accomplish with sound absorbing barriers.

The vibration can be heard inside and outside. The central air conditioner is by far the nosiest i have ever heard. Add sound deadening density by installing a layer of acoustical drywall to the inside surface of the outside. The more flexure in the roof the more difficult vibration isolation becomes.

Air conditioner is more exposed to leaves grass and organic matter. An effective way to dampen noise is to add mass between you and the air conditioner. Moisture builds up easier on the top of a patio stone. The proposed fix in this instance seems rather bizarre and horrendously expensive.

The ground around the outside unit actually shakes. Because the sound is reduced vibrations never begin and the problems are eliminated at the source. Roof construction is a critical element in controlling the amount of vibration transmitted from rooftop a c equipment.
