The customer had just spent a large amount of money on a new control system along with full building air balance. Which in turn only made the building comfort worse with lots of complaining tenants.
They were replacing cooling compressors every other week which was extremely costly and disturbing to the tenants.
We went through the entire building to find and system that was supposed to be balanced had disconnect duct work and mixing boxes so you could add all the controls and do all of the balancing you want and it was going to help.
We were able to get the boxes and duct work fixed. With our predictive diagnostics we were able to watch the compressors from Fargo. Which airflow and refrigerant issues which was causing the failure of the compressors.
