Krohn Refrigeration, located in Manalapan, NJ, does some air conditioning work, but only for its refrigeration customers. Founded in 1951 by Hans Krohn, CM, the Krohns are members of the Refrigeration Service Engineers Society (RSES).

The plan originally called for typical rooftop heating and cooling package units, and refrigeration condensing units on the ground outside. The architect had drawn the plans out this way and Krohn Refrigeration was ready to begin the work.

However, Sickles Farm Market, located in Little Silver, NJ, was having trouble getting final approval from the zoning board. The reason? Several residents living nearby raised concerns about noise from the air conditioning and refrigeration condensing units. That’s when the job got interesting.
