How to soundproof a very loud combination TRANE heat/ac unit?
« on: February 04, 2010, 12:10:59 AM »
Hi everyone:

Any suggestions for how to best soundproof a very noisy- vibrating combination Trane heating/ac unit?

The unit is a Trane Brand
Watersource Comfort System
http://www.trane.com/download/equipmentpdfs/wshpprc4.pdf

I was told by a Trane rep. that the unit is considered a  'Commercial' grade unit. Why a commercial grade unit was installed in a small scale residential application remains to be answered.

The unit is so loud the tv cannot be heard or one cannot use the telephone while it is operating.

If anyone has any suggestions on how to dampen the sound/vibration from this unit, your suggestions would be most appreciated.

Thank You

midnight

Hi.  My husband and I lived in a one bedroom apartment (just a rental) in NYC that had a very loud Trane, heating/air conditioning unit.  It was exceptionally noisy when it ran, and it clicked on/off very loudly.  When we moved in, it was a brand new, luxury, "green" building, and we were devastated with this unit.  We could never sleep with it on.  We had a Trane representative come to check it out, but there was nothing that he could do.  We purchased the best soundproofing material available (super thick MLV with super thick foam) and built a wooden box around it with the soundproofing material.  It did not help much and probably wasn't worth the effort.

I'm sorry!

When it comes to A/C units the most important principle is to decouple everything that you can from the structure. Not just the unit but the pipes that come from the unit into the structure, this is the real problem due to the fact that most pipes are hard mounted some where in the structure. Therfore allowing a faster than airborne path of sound transmission.

This is a very large problem that we visit quite often, adding barrier and foam will control airborne sound coming from the unit but if the unit is still hard mounted your results will be minimun at best.
