I called them up today, excellent service. He told me to try spraying WD-40 on the fan motor which did take care of the noise, well when I spayed it the first time he was on the phone and I told him there was some grinding noise and to call him back later if it happend again. Not even 10 min later he called back and said he is shipping out a new motor over night, he didnt want to take the chance of my chiller being down. So diffentaly A+++
