Have a chiller noisier than expected.

The discharge piping makes the casing and the oil separator resonate at a high pitch. Trane sells a sound deadening kit. It is not cheap, basically insulation to wrap the copressor, discharge piping, oil seperator.

Anyone ever try this kit? Did it work?

Take the "V" out of HVAC and you are left with a HAC(k) job.

Just an observation

With fire alarms, a rule of thumb is as you double the distance from a horn, the sound drops by 6 dB. The RTAA seemed to follow this pattern.

ended up building a block wall.

RTAAs were running louder than the spec

Have to measure the sound in the subdivision sometimes, but the neighbours seem appeased.
