AC performance tuneup times two systems. Philip did not have filters today, but he said he will change them soon. Only issue I found was the North unit needed 1 pound of 410 a refrigerant. Drains are flowing properly. There are no float switches on either unit to shut off the condenser in case of drain blockage. Phillip stated he would take care of that with a switch he could watch from his phone. Systems are cooling at manufacturers at this time.
