I just noticed a post about improving AC performance. They had a short YouTube Video showing water being sprayed on the condenser coil.
I’ve seen regular sprinklers used also. Typically, I see older compressors being treated this way. I also notice something going on inside. Typically the loads are not calculated correctly or something has changed inside. The other piece could be extremely high outdoor temperatures. I’ve seen this in homes, and businesses.
This is a restaurant, my long distance guess is a load issue. Was this originally built as a restaurant? Are the exhaust systems and economizers working and actually turned on?
