Your calculations for the load with all the humidity we are pumping into the room was dead on and it’s working like a champ. Again, thanks, we will be in touch if we need anything else. Best Regard

The installation of our new freezer/cooler was smooth and trouble free.  We are happy with the finished product and were well informed through the installation process of any changes in the time line due to unexpected conditions.  The crew was efficient, polite, and did not interfere with our daily processes.  We were very pleased with the process from start to finish.
